Infrastructure pivot frees up $1.3 billion USD for shareholders

Frontera Energy Corporation (TSX: FEC) (OTCQX: FECCF) reported first-quarter 2026 net income from continuing operations of $13.1 million USD and adjusted EBITDA of $28.5 million USD, as the Calgary-based company moves to close the sale of its Colombian exploration and production portfolio to Parex Resources Inc. (TSX: PXT) and reposition itself as a standalone Colombian infrastructure company anchored by its pipeline and port assets.

Total revenues from continuing operations were $26.8 million USD in the first quarter, compared with $26.9 million USD in the fourth quarter of 2025 and $25.1 million USD in the first quarter of 2025. Net loss for the period, including discontinued operations, was $15.4 million USD, reflecting a $28.5 million USD net loss from the Colombian E&P assets now classified as held for sale.

“In total, this strategy will have unlocked approximately $1.3 billion of capital for investors.” — Gabriel de Alba, Chairman of the Board, Frontera Energy Corporation

The Parex transaction

On April 30, 2026, Frontera shareholders approved a plan of arrangement under which Parex Resources, through a wholly-owned subsidiary, will acquire all of Frontera’s Colombian upstream business — including its oil and gas exploration and production assets, a reverse-osmosis water-treatment facility, and a palm-oil plantation. The transaction carries an enterprise value of $750 million USD. The cash purchase price consists of $500 million USD payable at closing, subject to customary adjustments, plus an additional $25 million USD contingent payment tied to specified development milestones to be achieved within 12 months of closing.

At the same shareholder meeting, investors approved a reduction of Frontera’s capital account of up to $647 million CAD (approximately $470 million USD) to fund a return of capital to shareholders from the net proceeds of the transaction. The Supreme Court of British Columbia issued its final order approving the arrangement on May 4, 2026. Closing remains subject to the satisfaction of remaining conditions and is expected in May 2026.

Chairman Gabriel de Alba said the company would retain roughly $50 million USD of cash to support growth opportunities at the remaining infrastructure business, including an LNG regasification project being developed in partnership with Ecopetrol (NYSE: EC) (BVC: ECOPETROL). “In total, this strategy will have unlocked approximately $1.3 billion of capital for investors,” de Alba said.

ODL pipeline drives cash flow

Frontera holds a 35 percent equity interest in the Oleoducto de los Llanos (ODL) crude oil pipeline, which connects the Rubiales, Quifa, Caño Sur, Llanos-34, and other production blocks to the Monterrey and Cusiana stations in the department of Casanare. ODL’s share of income contributed $14.2 million USD to Frontera in the first quarter, compared with $15.1 million USD a year earlier, with the year-over-year decline reflecting higher depreciation, amortization, and operating costs.

ODL transported 233,875 barrels per day in the first quarter of 2026 at an average tariff of $4.70 USD per barrel, compared with 236,387 barrels per day at $4.73 USD per barrel in the first quarter of 2025. The pipeline declared $185 million USD in total dividends, of which $64.7 million USD is net to Frontera. The company expects to receive those distributions during 2026 in installments of approximately 40 percent in the second quarter, 35 percent in the third quarter, and 25 percent in the fourth quarter.

Long-term debt at Frontera totaled $167.8 million USD at the end of the first quarter and is expected to decline to approximately $131 million USD by year-end 2026, primarily through scheduled amortizations and cash-sweep mechanisms tied to ODL cash flows. From May 2025 through December 2026, long-term debt is expected to fall by more than $100 million USD.

Puerto Bahía expands cargo mix

Puerto Bahía, the multipurpose maritime terminal located in Cartagena adjacent to the Bocachica access channel and near the Reficar refinery, generated $12.7 million USD in revenue in the first quarter of 2026, compared with $10.0 million USD in the same period a year earlier. The 150-hectare facility comprises a hydrocarbons terminal with nominal capacity of 2,672,000 barrels and a general cargo terminal. Frontera holds a 99.97 percent equity interest in the port.

General cargo growth offset weaker liquids volumes. The general cargo terminal handled 38,067 roll-on/roll-off (RORO) units in the first quarter, more than double the 18,223 units handled a year earlier, alongside 3,851 twenty-foot equivalent units (TEUs) of containerized cargo, up from 1,256 TEUs in the first quarter of 2025. Break-bulk volumes declined to 25,216 tons/m³ from 41,198 tons/m³. RORO dwell times shortened from 40 days to 31 days year over year.

The liquids terminal handled 36,937 barrels per day in the first quarter of 2026, down from 51,579 barrels per day a year earlier. Ecopetrol volumes accounted for 26,273 barrels per day, Frontera-related volumes for 7,389 barrels per day, and other third-party volumes for 3,275 barrels per day. The company attributed the decline mainly to lower third-party throughput and the absence of certain trading flows.

Operating costs at the port rose to $7.6 million USD in the first quarter from $5.0 million USD a year earlier, driven by increased infrastructure maintenance in the liquids terminal and higher cargo volumes in the general cargo facility.

LPG and LNG projects advance

Puerto Bahía’s liquefied petroleum gas (LPG) project began initial operations in March 2026, providing capacity to handle up to 10,000 tons per month. The terminal is targeted to become fully operational during the first quarter of 2028. Capital expenditures during the first quarter totaled $1.0 million USD, including $0.4 million USD for major tank maintenance and $0.3 million USD for the LPG project.

The company is also advancing an LNG regasification project at Puerto Bahía in partnership with Ecopetrol, intended to support Colombia’s domestic gas supply as domestic production declines. Frontera is also pursuing expansion of containerized cargo operations.

Discontinued operations

Following the execution of the arrangement agreement, the Colombian E&P assets are now classified as discontinued operations under IFRS 5. Colombian production averaged 36,700 barrels of oil equivalent per day in the first quarter of 2026, comprising 25,394 barrels per day of heavy crude, 8,653 barrels per day of light and medium crude combined, 5,706 thousand cubic feet per day of conventional natural gas, and 1,652 barrels of oil equivalent per day of natural gas liquids. That compares with 39,010 barrels of oil equivalent per day a year earlier.

The operating netback from the discontinued Colombian operations was $41.79 USD per barrel of oil equivalent in the first quarter of 2026, compared with $34.22 USD per barrel of oil equivalent in the first quarter of 2025, supported by a higher Brent reference price of $78.38 USD per barrel against $74.98 USD per barrel a year earlier.

Frontera retains exploration and development interests in Guyana through subsidiaries that include CGX Energy Inc. (TSXV: OYL), which is not part of the Parex transaction. The company’s go-forward portfolio will be anchored by the ODL pipeline stake and Puerto Bahía, with the infrastructure business generating approximately $77 million USD of distributable cash flow in 2025, according to the management information circular dated March 30, 2026.

GEB-La Caisse JV to rank among Brazil’s top five power transmitters

Grupo Energía Bogotá (BVC: GEB) and La Caisse, the investment arm of Caisse de dépôt et placement du Québec, have signed a final agreement to merge their respective Brazilian power transmission assets into a single 50/50 jointly controlled platform operating under the name Verene Energia S.A. The transaction was announced May 15, 2026, from Montréal and Bogotá.

The combined entity will consolidate 26 electric transmission concession agreements, more than 9,000 km of transmission lines, and a workforce of over 400 employees across 17 Brazilian states. At that scale, Verene will rank among the five largest power transmission operators in Brazil, a market that has drawn sustained interest from international infrastructure investors as the country advances grid modernization programs.

Verene, which had previously operated as La Caisse’s dedicated transmission platform in Brazil, will continue as the reference vehicle for the combined portfolio. The partners have indicated that the platform will be positioned to pursue acquisitions and network expansions in Brazil’s transmission concession market, with grid modernization and decarbonization cited as the broader policy context driving new investment opportunities.

“By bringing together highly complementary assets under one banner, the partnership establishes Verene as a scaled, business-driven platform with strong financial backing.” — Emmanuel Jaclot, Executive Vice-President and Head of Infrastructure and Sustainability, La Caisse

Grupo Energía Bogotá, headquartered in Bogotá and listed on the Bolsa de Valores de Colombia (BVC: GEB), has operated in Latin America’s energy sector for more than 130 years. The company holds assets in electricity generation, transmission, distribution, and gas transportation and distribution across Colombia, Peru, Brazil, and Guatemala. Its entry into the joint venture contributes its existing Brazilian transmission concessions to the merged platform alongside La Caisse’s Verene assets.

La Caisse manages net assets of 517 billion CAD as of December 31, 2025, on behalf of 48 depositors representing more than six million Quebecers. The fund is active across major financial markets, private equity, infrastructure, real estate, and private credit, and has built a significant infrastructure portfolio in Latin America through investments including the Verene platform.

Juan Ricardo Ortega, president of Grupo Energía Bogotá, described the rationale for the transaction in terms of combining complementary strengths. “By combining our operational expertise and regional market knowledge with the financial strength and global perspective of our partner, we are creating a platform positioned to accelerate growth, expand transmission energy infrastructure, and support Brazil’s energy transition,” he said. “We believe this alliance will generate sustainable value for our stakeholders and contribute to Brazil’s economic and energy development.”

Emmanuel Jaclot, executive vice-president and head of infrastructure and sustainability at La Caisse, framed the deal as a consolidation play. “By bringing together highly complementary assets under one banner, the partnership establishes Verene as a scaled, business-driven platform with strong financial backing,” Jaclot said. “GEB brings more than 130 years of operating heritage and ranks among Latin America’s leading energy infrastructure groups, with deep expertise across the region’s transmission sector. Together, we share a vision to strengthen Verene’s footprint in Brazil through value-creating acquisitions and continued support for the country’s energy transition.”

Financial close is expected by the fourth quarter of 2026, subject to customary closing conditions, regulatory consents, and approvals. BTG Pactual (BVMF: BPAC11) acted as financial advisor to La Caisse, with Pinheiro Neto Advogados serving as legal counsel. Citibank (NYSE: C) advised Grupo Energía Bogotá on the financial side, while Mayer Brown provided legal advice to GEB.

Infrastructure Progress Advances Marmato 2026 Gold Production Goals

Aris Mining (TSX: ARIS; NYSE: ARIS) confirmed the completion of an underground infrastructure connection at its Marmato gold mine in Colombia. The development involved connecting a new surface decline to the existing underground mining workings.

This cross-cut connection serves as a technical step for the ongoing expansion project, which includes the construction of a 5,000 tons-per-day carbon-in-pulp (CIP) plant. The company stated that the infrastructure is currently on schedule to support the initiation of gold production in the fourth quarter of 2026.

Neil Woodyer, Chair and CEO of Aris Mining, stated: “The on-schedule connection of the new surface decline to the existing underground development is a major milestone for Marmato and an important step in delivering our expansion plans.”

The Marmato expansion is part of a broader strategy intended to increase the company’s annual gold production. Aris Mining aims to achieve a combined output of approximately 500,000 ounces per year from its Segovia and Marmato operations. The Segovia mine previously expanded its operational capacity following the installation of a second mill in June 2025.

The company maintains a long-term production objective of approximately 1 million ounces of gold annually. This target incorporates potential production from the Toroparu gold project in Guyana, where a prefeasibility study is currently underway. Aris Mining expects a construction decision regarding the Toroparu project in early 2027.

Regarding its portfolio in Colombia, the company is finalizing environmental studies for the Soto Norte gold project. Aris Mining plans to submit these documents for the licensing process during the second quarter of 2026.

Sector adapts to investment decline through secondary asset markets.

The mining industry in Colombia is undergoing a structural transformation as companies prioritize operational efficiency to navigate a challenging economic environment. Recent industry data shows the mining Producto Interno Bruto (GDP) contracted by approximately 8%, while foreign direct investment has experienced a notable downturn. This trend has prompted firms to seek innovative financial strategies to maintain sustainability and competitiveness.

A primary strategy gaining traction is the rotation of underutilized industrial assets. By leveraging industrial auctions, companies are liquidating idle machinery—such as excavators, drilling rigs, and heavy-duty power equipment—to recover capital without the necessity of maintaining internal commercial structures. Superbid, a multinational industrial auction platform, has emerged as a key facilitator for these transactions within the region.

“Asset rotation is becoming a strategic decision to free up capital and improve operations.” — Maria Paula Villa Velez, Superbid

This operational shift toward asset-light business models will be a central topic at MINEXPO Colombia 2026, which is scheduled to take place on April 15 and 16 at Plaza Mayor Medellín. The event serves as a platform for mining producers, suppliers, and investors to discuss strategies for financial optimization and industrial reindustrialization.

The secondary market for industrial equipment has expanded significantly as mining companies divest assets no longer essential to their core operations. This machinery is being repurposed in the infrastructure, construction, and energy sectors, thereby extending the lifecycle of the assets and contributing to circular economy objectives. Market participants have observed increased competition for this equipment, with buyers consistently acquiring assets at market-determined values.

Looking toward the remainder of 2026, industry analysts expect the integration of these efficient asset management models to accelerate, particularly in regions such as Antioquia, where the nexus of mining and infrastructure projects remains a critical economic driver.

“Today the mining sector is understanding that efficiency is not only in producing, but in better managing its resources,” stated Maria Paula Villa Velez, sub-manager at Superbid Medellin. “Asset rotation is becoming a strategic decision to free up capital and improve operations.”

New luxury hospitality project strengthens Cartagena’s investment profile.

Four Seasons Hotel and Residences Cartagena officially opened on April 2, 2026, marking the third property for the hospitality brand in Colombia. The project is a joint venture with San Francisco Investments, a subsidiary of the Valorem holding company. Located in the Getsemaní neighborhood, the hotel is situated near the UNESCO World Heritage Site Walled City and the Cartagena Convention Center.

The development involved the multi-year restoration of several historic buildings, including the 1920s-era former Club Cartagena. The architectural and interior design was led by the late François Catroux, with additional technical expertise provided by WATG and Wimberly Interiors. The food and beverage concepts were developed by SBM Interior Design and AvroKO. Landscape architecture for the rooftop and grounds was managed by Enea Garden Design, led by Carolina Jaimes.

“Welcoming a third Four Seasons to Colombia, joining our Bogotá and Casa Medina Bogotá properties, marks an important milestone in the continued expansion of our global portfolio,” said Rainer Stampfer, Four Seasons President of Global Operations, Hotels and Resorts.

The hotel features 131 guest rooms, 27 of which are colonial-style suites located within the heritage wing. These units include preserved architectural elements and custom furnishings designed by Poli Mallarino. The property also contains Private Residences designed by Rodriguez Valencia Arquitectos. The primary presidential suite, known as the Catroux Suite, features a private elevator and a terrace with a Moorish-inspired fountain by María Cecilia Franco Berón.

There are eight dining and drinking venues on the property. The Grand Grill and Bar Lelarge were conceptualized by Major Food Group, focusing on steakhouse traditions and seasonal cocktails. Additional venues include Café Rialto, Pizzeria Della Chiesa, El Aljibe, El Patio del Limonar, and the rooftop sunset lounge, El Palmar. Lighting for these venues was designed by Lang Lighting Design.

Wellness facilities include the Umari Spa, which offers six treatment rooms and uses botanical ingredients derived from the umari plant. For business events and social functions, the hotel provides several spaces, including the Ballroom de la Veracruz, which can host 300 guests and features a centuries-old fresco. The Ballroom Centenario provides views of the Walled City for smaller gatherings of up to 100 people.

Four Seasons Hotels and Resorts is a global hospitality company partially owned by Kingdom Holding Company (TADAWUL: 4280). The company currently operates 136 hotels and 61 residential properties across 47 countries, with more than 60 projects currently in its development pipeline. In Cartagena, the hotel operations are led by General Manager Annie Monnier.

Renewable expansion strengthens Colombia energy matrix for investors.

The Norwegian renewable energy company Scatec ASA (OSE: SCATC) has reached financial close and initiated construction on the Barzalosa solar power plant in Colombia. The project, located in the municipio of Nariño within the department of Cundinamarca, has a planned capacity of 130 MWp. Total capital expenditure for the facility is estimated at $121 million USD.

The financing structure for the project is based on a 70% leverage model, utilizing a combination of equity and non-recourse debt. Scatec holds a 65% equity stake in the venture, while Norfund, the Norwegian investment fund for developing countries, provides the remaining 35%. The senior debt was provided by Bancolombia S.A. (NYSE: CIB; BVC: BCOLOMBIA) and the Financiera de Desarrollo Nacional (FDN).

The Financiera de Desarrollo Nacional committed a total of 200,358 million COP to the project. This includes a senior debt facility of up to 164,458 million COP with a term of 18 years, representing approximately 50% of the total project debt. Additionally, the FDN provided a bank guarantee of up to 35,900 million COP to substitute reserve accounts for debt service and operation and maintenance costs. The FDN also acted as a co-structurer for the financial framework of the operation.

“The financing of the Barzalosa project reflects the capacity of the FDN to structure long-term financial solutions that make strategic energy transition projects in Colombia viable,” said Enrique Cadena, Vice President of Structured Finance at the FDN.

The law firm Holland & Knight served as legal counsel to the lenders, Bancolombia and FDN, in the COP 330 billion financing transaction. The legal team was led by partner María Juliana Saa, with support from partner Inés Elvira Vesga and associates Juan Sebastián Parra and Juan Felipe Alonso. Other legal and financial advisors involved in the transaction included Cuatrecasas, which advised the borrower; Brigard Urrutia, which advised FDN regarding the credit facility; and Astris Finance, which provided financial structuring advice.

Revenue for the plant will be supported by a 15-year Power Purchase Agreement (PPA) with BTG Pactual Comercializadora de Energía (BVMF: BPAC11). The agreement covers 85% of the estimated energy production and is denominated in Colombian pesos, with adjustments based on the Producer Price Index. The remaining 15% of production will be sold on the Colombian spot market. The project is also eligible for the Cargo por Confiabilidad (reliability charge) and may access resources from the Inter-American Development Bank and the Climate Investment Funds.

Construction includes the installation of the solar array and the development of a six-kilometer transmission line to connect the plant to the national grid. Scatec is acting as the lead developer and the designated Engineering, Procurement, and Construction (EPC) provider, covering approximately 70% of the capital expenditure. The company will also manage operations, maintenance, and asset management. The Barzalosa plant is expected to reach its commercial operation date in the first half of 2027.

Aris Mining Corporation (TSX: ARIS; NYSE: ARIS) has released its financial and operating results for the fourth quarter and full year ending December 31, 2025. The company reported 2025 gold production of 256,503 ounces, a 22% increase from the 210,955 ounces produced in 2024. This output exceeded the midpoint of the company’s annual guidance of 230,000 to 275,000 ounces.

Annual gold revenue reached $909 million USD, representing an 82% increase over the previous year. Adjusted EBITDA rose to $464 million USD, up 185% from 2024, while adjusted net earnings were reported at $241 million USD, or $1.28 USD per share. As of year-end 2025, the company’s cash balance stood at $392 million USD, with net debt reduced to $86 million USD from $241 million USD at the end of 2024.

The Marmato Mine produced 28,741 ounces of gold, a 23% increase over the 2024 production level.

Operational Performance at Segovia and Marmato

Operations at the Segovia Operations in Colombia produced 227,762 ounces of gold in 2025, a 21% increase from 2024. This performance was supported by average gold grades of 9.82 g/t and a 17% increase in tonnes milled, following the installation of a second ball mill in June 2025. All-in sustaining costs (AISC) for owner-operated mining at Segovia were $1,534 USD per ounce, while AISC for Contract Mining Partners (CMPs) was $1,973 USD per ounce, reflecting a purchase formula linked to rising gold prices.

The Marmato Mine produced 28,741 ounces of gold, a 23% increase over the 2024 production level. The result exceeded the 2025 guidance range of 20,000 to 25,000 ounces. The company is currently advancing construction of a new carbon-in-pulp (CIP) processing facility at Marmato, with first gold production expected in the fourth quarter of 2026.

2026 Outlook and Project Development

Aris Mining has set its 2026 consolidated gold production guidance between 300,000 and 350,000 ounces. Production is expected to be weighted toward the second half of the year as the Marmato CIP plant begins operations. At Segovia, production is forecast to increase to between 265,000 and 300,000 ounces.

The company also provided updates on its development portfolio:

• Soto Norte Project (Colombia): Aris Mining completed a Prefeasibility Study (PFS) in September 2025. The company intends to submit an environmental license application to the Autoridad Nacional de Licencias Ambientales (ANLA) in the second quarter of 2026.
• Toroparu Project (Guyana): A Preliminary Economic Assessment (PEA) was completed in October 2025, and a PFS is currently underway with a targeted completion in 2026. A construction decision is anticipated in early 2027.

In the fourth quarter of 2025, Aris Mining used $60 million USD in cash for the acquisition of the remaining 49% interest in the Soto Norte project. Subsequent to the year-end, the company received a $40 million USD installment deposit under its precious metals stream financing after reaching a 50% construction milestone at Marmato.

Aris Mining’s operations are subject to oversight by the Agencia Nacional de Minería (ANM) in Colombia and the Guyana Geology and Mines Commission (GGMC) in Guyana.

Frontera must pay a $25 million USD breakup fee to Geopark.

Frontera Energy Corporation (TSX: FEC) has entered into a definitive arrangement agreement to divest its Colombian upstream exploration and production (E&P) portfolio to Parex Resources Inc. (TSX: PXT) for a total firm value of approximately $750 million USD. The transaction follows the termination of a previous agreement with GeoPark Limited (NYSE: GPRK). Frontera opted for the Parex proposal after the Calgary-based independent producer offered $525 million USD in equity consideration, a $125 million USD increase over the prior GeoPark bid. As part of the transition, Frontera has paid a $25 million USD breakup fee to GeoPark.

The $525 million USD equity consideration includes an immediate $500 million USD cash payment upon closing and a $25 million USD contingent payment. The latter is dependent on the execution of a contractual amendment or binding agreement to extend the term of the Quifa Association Contract within 12 months.

Beyond the cash equity, Parex will assume $390 million USD in existing Frontera liabilities. This includes $310 million USD in 2028 Senior Unsecured Notes and an $80 million USD prepayment facility with Chevron Products Company, a subsidiary of Chevron Corporation (NYSE: CVX).

Following the close of the deal, Frontera intends to distribute approximately $470 million USD to its shareholders, which equates to roughly $9.18 CAD per share based on current exchange rates and outstanding share counts. This distribution is subject to shareholder approval and the successful completion of the transaction.

Frontera is retaining its exploration interests in Guyana.

Shift to Infrastructure Focus

Upon completion, Frontera will pivot its corporate strategy to focus exclusively on energy infrastructure. Its remaining portfolio will be anchored by two primary Colombian assets:

• A 35% equity interest in Oleoducto de los Llanos Orientales S.A. (ODL), a critical crude oil pipeline.
• A 99.97% equity interest in Sociedad Portuaria Puerto Bahía, a multipurpose port facility in Cartagena.

The company will also retain its exploration interests in Guyana. Frontera’s infrastructure division generated approximately $77 million USD in distributable cash flow in 2025. Post-transaction, Frontera expects to maintain $50 million USD in cash reserves to fund growth projects, including a potential Liquefied Natural Gas (LNG) regasification project in partnership with Ecopetrol S.A. (NYSE: EC; BVC: ECOPETROL).

Orlando Cabrales, CEO of Frontera, noted that Parex is currently the largest independent operator in Colombia and a pre-existing partner in the VIM-1 block, which suggests operational continuity for the assets and employees involved.

The independent members of Frontera’s Board of Directors have unanimously recommended the deal. Major shareholders The Catalyst Capital Group Inc. and Gramercy Funds Management LLC, who collectively hold approximately 53% of Frontera’s outstanding shares, have signed support agreements to vote in favor of the arrangement.

Timeline and Approvals

The transaction is structured as a plan of arrangement under the Business Corporations Act of British Columbia. It requires the approval of at least two-thirds of the votes cast by Frontera shareholders at a forthcoming special meeting.

The deal is also subject to approval by the Supreme Court of British Columbia and relevant regulatory bodies in both Canada and Colombia. Parex will fund the acquisition through existing cash, credit facilities, and an underwritten financing commitment from Scotiabank (TSX: BNS; NYSE: BNS). Closing is anticipated in the second quarter of 2026.

Citi (NYSE: C) served as the financial advisor to Frontera, while BMO Nesbitt Burns Inc. provided a fairness opinion. Legal counsel was provided by Blake, Cassels & Graydon LLP and McMillan LLP.

Colombia’s security forces alerted late Sunday Medellín Mayor Federico Gutiérrez and Antioquia Governor Andrés Julián Rendón to cancel a planned visit to the Hidroituango hydroelectric complex for Monday, March 2, after intelligence warnings of a possible drone attack and credible terrorist threat.

The visit, which included a press conference expected to draw around 100 journalists, was intended to showcase progress at the country’s largest hydroelectric project, now reported to be 95% complete. Instead, regional officials said army security recommendations prompted an abrupt suspension after the detection of unauthorized drone activity over the area.

“The recommendation of the National Army is that the trip be postponed given the detected presence of large, unauthorized drone overflights,” the Antioquia governor’s office said in a statement, adding that the devices were believed to be operated by the 36th Front of dissident Revolutionary Armed Forces of Colombia (FARC) guerrilla.

Officials said the threat was not speculative. Security teams warned that an attack could materialise during the public event, raising concerns not only for the two high-profile politicians but also for members of the press corps and technical staff.

Rendón told Caracol Radio that the drones had been observed manoeuvring persistently over the precise location where the press conference was scheduled to take place. The activity coincided with a recent military operation in the nearby municipality of San Andrés de Cuerquia, where troops seized a drone, explosives, detonators, radios and military-style clothing from the same dissident group.

“All of this is highly coincidental,” Rendón said, adding that authorities were analyzing whether the overflights formed part of reconnaissance ahead of a planned attack.

Gutiérrez said armed groups were seeking to destabilize the country and disrupt key infrastructure. “These terrorist groups want to shut down the country, to generate damage,” he said, pointing to ongoing threats against Empresas Públicas de Medellín (EPM), the state-owned utility responsible for the project.

The cancelled visit had both symbolic and operational significance. In addition to reviewing construction progress and the installation of four turbines, officials were expected to outline new revenue flows generated by the project for Medellín and the wider Antioquia department.

Hidroituango has long been a flagship infrastructure initiative, though it has also faced years of engineering setbacks, financial strain and political scrutiny.

The press event has been rescheduled to take place in Medellín’s La Alpujarra administrative complex under heightened security.

The incident underscores growing concern over the rapid adoption of drones by illegal armed groups. Once limited to reconnaissance, commercially available drones modified to carry explosives are now being used in targeted attacks across conflict-prone regions of the country, including the southwest departments of Nariño, Cauca and Valle del Cauca.

According to military data, more than 400 drone-related attacks have been recorded in Colombia over the past two years, reflecting a sharp escalation in both frequency and sophistication. Analysts say such devices offer armed groups a low-cost, high-impact means of striking military, civilian and infrastructure targets while reducing direct exposure.

Recent attacks in Antioquia highlight the trend. In rural Segovia, a drone-delivered explosive killed three members of a family and displaced more than 100 households amid clashes between FARC dissidents and the Gulf Clan criminal group last week. In Ituango, the nearrest municiplity to the power-generating damn, another drone attack targeted a fuel station using improvised explosives.

On Saturday, in southern Bolívar, a military helicopter was struck in a drone attack attributed to the National Liberation Army (ELN) guerrilla, leaving 14 soldiers injured. Colombian military officials say some armed groups may have received external training in the use of drones for covert operations.

Colombia’s armed forces are moving to adapt to the emerging threat, announcing last October the creation of a specialized “Drone Battalion” aimed at strengthening aerial surveillance and counter-drone capabilities. However, security experts warn that defending against small, low-flying devices — some costing as little as US$600 — remains a significant challenge, particularly in mountainous terrain like that surrounding Hidroituango.

The alleged plot has also raised concerns about a possible shift in targeting strategy by armed groups, from rural security forces to high-profile political figures and critical infrastructure ahead of the May 31 presidential elections.

While no attack ultimately took place, authorities say the decision to cancel the visit reflects the seriousness of the threat.

For now, officials are treating the incident as a direct warning of how Colombia’s long-running conflict is evolving – increasingly shaped by technology, and capable of reaching beyond traditional conflict zones into strategic economic and political targets.
