Higher grades at Segovia drive output and revenue gains

Vancouver-based Aris Mining Corporation (TSX: ARIS; NYSE: ARIS) reported preliminary first-quarter 2026 gold production of 74,300 ounces from its two underground mines in Colombia, representing a 6% increase over the fourth quarter of 2025 and a 36% increase compared to the same period a year earlier.

The company said it sold 74,800 ounces of gold during the quarter at an average realized price exceeding $4,860 USD per ounce, generating gold revenue of more than $360 million USD. That figure marks a 20% increase from Q4 2025 revenue of $301 million USD and more than double the $154 million USD reported in Q1 2025. The company reported a cash balance exceeding $470 million USD as of March 31, 2026, an increase of approximately $80 million USD from the end of the previous quarter.

“We expect Q1 2026 gold revenue to exceed $360 million, a significant increase from $154 million in Q1 2025 and $301 million in Q4 2025, driven by higher gold prices and increased ounces sold.” — Neil Woodyer, Chair and CEO, Aris Mining Corporation

The production gains were concentrated at Aris Mining’s Segovia operation in the department of Antioquia, which produced 66,600 ounces during the quarter, up from 63,100 ounces in Q4 2025 and 47,500 ounces in Q1 2025. The year-over-year increase of 40% at Segovia was driven primarily by a notable improvement in ore grade. The average gold grade processed rose to 12.41 grams per ton from 9.37 grams per ton a year earlier, a 32% increase, while the volume of ore processed increased 5% to 175,000 tons. Recovery rates held at 95.3%, compared to 96.1% in both the prior quarter and Q1 2025.

The higher grades offset a decline in throughput compared to Q4 2025, when the mine processed 201,000 tons at an average grade of 10.10 grams per ton. Aris Mining completed installation of a second mill at Segovia in June 2025, increasing processing capacity by 50% to 3,000 tons per day, and the company has indicated that the ramp-up at the operation is continuing.

At the Marmato mine in the department of Caldas, production totaled 7,800 ounces in Q1 2026, an increase from 6,700 ounces in Q4 2025 and 7,200 ounces in Q1 2025. Marmato processed 77,000 tons of ore at an average grade of 3.53 grams per ton during the quarter, compared to 75,000 tons at 3.12 grams per ton in Q4 2025. Recovery rates at Marmato declined slightly to 89.6% from 90.8% in the prior quarter.

Consolidated Production Summary

Growth Outlook

Neil Woodyer, the company’s chair and CEO, said production growth in 2026 is expected to be weighted toward the second half of the year. The company is building a new bulk mine and carbon-in-pulp (CIP) processing plant at Marmato, with first gold expected in Q4 2026. At steady state, the expanded Marmato operation is expected to produce approximately 200,000 ounces per year.

Together, the Segovia and Marmato expansions are expected to increase Aris Mining’s annual gold production to approximately 500,000 ounces. The two mines produced a combined 257,000 ounces in 2025.

Beyond its operating mines, Aris Mining is advancing the Soto Norte gold project in the department of Santander, Colombia, where environmental studies are being finalized for submission in Q2 2026 to initiate the licensing process. The company also holds the Toroparu gold project in Guyana, where a prefeasibility study is underway and a construction decision is expected in early 2027. These projects form part of Aris Mining’s longer-term objective of reaching approximately 1 million ounces of annual gold production, though that target includes estimates from a preliminary economic assessment for Toroparu that the company has cautioned are based on inferred mineral resources and are speculative in nature.

The company expects to report full Q1 2026 financial and operating results on or about May 6, 2026. The quarterly results contained in the April 7 announcement are preliminary and may differ from final figures.

Aris Mining is listed on the Toronto Stock Exchange and the New York Stock Exchange under the ticker symbol ARIS. Company filings are available through SEDAR+ and the US Securities and Exchange Commission.

Berlin has historically reported indications of Rare Earth Elements, Vanadium, Phosphate and Uranium — Positioned as Potential Non-Chinese Critical Minerals Project in the Western Hemisphere

TORONTO — Jaguar Uranium Corp. (NYSE American: JAGU) has commenced an initial rare earth element assessment program at its flagship Berlin Project in Caldas, Colombia. The site is a polymetallic sedimentary deposit containing uranium mineralization alongside associated rare earth elements (REE) and battery-related commodities such as vanadium, phosphate, nickel, molybdenum, rhenium, and yttrium.

The company plans to utilize approximately 20,000 meters of preserved historic drill core for selective re-sampling and assaying. This approach is intended to advance early-stage REE characterization without the immediate requirement for new drilling. The program represents the first dedicated effort by the company to evaluate the rare earth potential of the 9,053-hectare concession area.

“The results could be a step-change in how this project is understood and technically evaluated.” — Steven Gold, Chief Executive Officer, Jaguar Uranium Corp.

“We are now attempting to advance the recognition that Berlin could represent a relevant non-China based critical mineral deposits in the western hemisphere and specifically in Latin America,” stated Steven Gold, Chief Executive Officer of Jaguar Uranium Corp. “We believe the results could be a step-change in how this project is understood and technically evaluated.”

The strategic shift toward REE evaluation follows a period of increased global policy attention regarding critical mineral supply chains. Materials required for defense systems, electric vehicles, and clean energy infrastructure have become a priority for Western governments seeking to diversify away from Chinese-dominated markets. Gracelin Baskaran, director of the Critical Minerals Security Program at the Center for Strategic and International Studies (CSIS), has indicated that the US and the European Union are working to foster independent markets for these materials.

The Berlin Project deposit is situated within a layered sedimentary sequence of phosphate-bearing limestone. The company is employing a three-phase approach for its assessment: core logging and systematic re-sampling, multi-element geological modeling, and an evaluation of by-product economics. This modeling will integrate REE assay data with existing datasets for uranium, vanadium, and phosphate to establish a technical foundation for future resource estimates.

Infrastructure at the site includes proximity to a hydroelectric power source 12 kilometers away and access to a river port approximately 65 kilometers from the project, providing a logistical route to the Caribbean coast. The company, which completed a $25 million USD initial public offering on the NYSE American (NYSE American: JAGU) in February 2026, is also managing the Laguna Salada Project in the Argentine province of Chubut and the Huemul mine in Mendoza.

Technical information regarding the program was approved by Owen D. W. Miller, a qualified person as defined by NI 43-101. The company noted that the Berlin Project remains in the exploration stage and does not currently host mineral resources or reserves as defined under SEC Regulation S-K 1300.

On December 3, 2025, Collective Mining Ltd. (NYSE: CNL, TSX: CNL) announced assay results from three orthogonal diamond drill holes designed to continue expanding the high-grade Ramp Zone (“Ramp”), a component of the company’s flagship Apollo system within the Guayabales Project in Caldas, Colombia.

The results confirm broad and continuous intervals of reduced intrusion-related gold mineralization, extending the Ramp Zone to 300 meters of strike by 270 meters vertical. The company stated that the zone remains open in all directions.

The Ramp Zone, situated at approximately 1,000 meters above sea level at the bottom of the Apollo system, is part of a large, partially Reduced Intrusion Related System (RIRS) mineralized with gold, silver, copper, and tungsten. Drilling at Apollo has outlined continuous mineralization from the surface to more than 1,370 vertical meters.

Drill Hole Results Detail

The deepest and northeastern-most hole reported to date, APC143-D1, intercepted 23.35 meters grading 8.24 g/t gold and 8 g/t silver. This intercept was contained within a broader interval of 76.10 meters grading 3.26 g/t gold and 4 g/t silver, starting from 409.60 meters downhole. This result expanded the Ramp Zone’s dimensions from the previously stated 275 meters of strike by 200 meters vertical.

A second hole, APC140-D2, locally extended the Ramp Zone by 50 meters to the northwest. This hole cut 16.40 meters grading 8.44 g/t gold and 19 g/t silver within a 55.10-meter interval grading 3.06 g/t gold and 7 g/t silver, beginning at 243.10 meters downhole.

A related wedge hole, APC140-D1, intersected two mineralized segments: 47.70 meters grading 1.98 g/t gold and 5 g/t silver from 527.40 meters downhole, including 15.15 meters grading 3.00 g/t gold and 8 g/t silver; and 14.15 meters grading 2.13 g/t gold and 4 g/t silver from 598.55 meters downhole.

Operational and Financial Status

The company has contracted a third deep-capacity diamond rig to operate at the Ramp Zone, with two additional deep-capacity rigs scheduled to arrive in mid-Q1 2026. Two additional drill holes into the Ramp Zone (APC143-D2 and APC143-D3) are pending assay results; these holes were reported to have intersected 18 sightings of visible gold, compared to none observed in the results detailed in this announcement.

To date, Collective Mining has completed 150,000 meters of diamond drilling across the Guayabales and San Antonio projects, with 105,000 meters dedicated to the Apollo system. Ten rigs are currently operating on site.

The company stated that it is fully funded for its aggressive 2026 program, which targets up to 100,000 meters of additional drilling, based on a cash position of $135 million USD as of December 1, 2025.

Executive Chairman Ari Sussman commented on the results, noting that hole APC143-D1 extended the zone along strike and at depth and demonstrated consistent mineralization over substantial widths.

The continued presence of Ramp Zone mineralization at least 270 meters beneath the initial discovery at 1,000 meters above sea level supports the view that the drilling may have only tested the top of a large intrusion-related gold system that shares mineralogical similarities with the multi-million ounce Marmato Deeps Zone.
