Mercado Minerals (MRMNF) reported new surface sampling results and an expanded El Triunfo vein at its Zamora Project in Mexico. Mapping and sampling more than doubled the known vein strike length from 180 metres to over 370 metres. A chip sample across 1.55 metres true width returned 381 g/t silver and 0.85 g/t gold, including 0.60 metres of 815 g/t silver and 1.66 g/t gold.
A stockpile grab sample from a newly discovered second historic working returned 674 g/t silver and 1.00 g/t gold. Another chip sample returned 128 g/t silver and 0.26 g/t gold over 0.60 metres. Preparations for an inaugural 1500 metre drill program are ongoing, with drill roads and pads under construction. Mercado expects initial drill testing in the coming weeks.
Mercado Minerals (MRMNF) reported new surface silver and gold sampling results from its Zamora project in Sinaloa, Mexico.
A Campanillas - La Franca chip sample returned 0.40 metres of 1615 g/t silver and 1.77 g/t gold. The vein's reported strike length reached 800 metres. At El Triunfo, mapping delineated 180 metres of strike length; a stockpile grab sample returned 1075 g/t silver and 1.14 g/t gold, while a 0.40-metre chip sample returned 558 g/t silver and 3.52 g/t gold. Initial chip samples also returned silver and gold at Aguamitas and Periguete. Mercado expects first drill testing of these targets in the coming weeks. The La Franca concession remains under a letter of intent.
Mercado Minerals (MRMNF) signed a Letter of Intent to option 100% of the La Franca concession within its Zamora project in Mexico.
The contemplated definitive agreement grants a three-year option via staged cash payments totalling US$600,000, while the asset remains subject to a 2% Net Smelter Return royalty, fully buyable for US$500,000. Consolidating La Franca with Mercado’s surrounding Campanillas concession would create 750 metres of continuous, high-grade silver-gold vein strike that has never been drill tested. Recent 2026 chip samples from La Franca include 1.00 metre at 1,530 g/t silver and 1.39 g/t gold (1,501 g/t AgEq) and 0.80 metre at 534 g/t silver and 3.58 g/t gold (757 g/t AgEq), alongside historical grab samples up to 1,720 g/t silver and 12.96 g/t gold (2,530 g/t AgEq). Mercado plans to begin permitting for an inaugural diamond drill program at Campanillas–La Franca.
Mercado Minerals (MRMNF) reported initial surface chip sampling results from its Zamora project’s Campanillas Vein in Sinaloa, Mexico.
The 2026 program has mapped and sampled a 300 metre strike length, doubling the previously known strike. Highlight intercepts include 2.40 metres (true width) grading 528 g/t silver and 0.75 g/t gold (536 g/t AgEq), with an internal 1.00 metre interval of 828 g/t silver (760 g/t AgEq), the highest-grade surface composite yet at Campanillas. Systematic sampling shows approximate true widths between 0.60 and 2.40 metres, silver grades from 2 to 828 g/t and gold from 0.04 to 1.66 g/t. Mercado states that mineralized vein and wallrock at surface appear wider than in historic underground workings. Detailed QA/QC procedures and independent NI 43-101 review are described.
Mercado Minerals (OTCQB: MRMNF) announced that its subsidiary Concordia Silver Company has signed a community access and exploration agreement with Ejido Rincon de Ibonia covering part of the Zamora silver-gold project in Sinaloa, Mexico. The agreement enables Mercado to advance and complete the drill permit process, initially focused on the Campanillas area.
According to Mercado, the company will pay an annual fee of 100,000 MXN with a one-year renewal option, plus 3,000 MXN per drill pad to mitigate land impacts. Mercado continues discussions with other Ejido groups for broader access. Historic sampling at Zamora returned high silver-gold grades, but these results are treated as historical and will be independently verified by a Qualified Person under NI 43-101.
Mercado Minerals (OTCQB: MRMNF) reported results from its inaugural 25‑hole diamond drill program at the Copalito silver project in Sinaloa, Mexico, testing seven vein structures. Drilling expanded mineralization on the 5 Señores, El Agua and El Pilar veins and confirmed several new targets.
Key intercepts include 7.60 m of 340 g/t silver and 1.22 g/t gold at 5 Señores, 3.50 m of 30 g/t silver, 1.94 g/t gold, 9.47% lead and 14.61% zinc at El Agua, and 3.40 m of 11 g/t silver, 3.53 g/t gold, 1.45% lead and 4.41% zinc at El Pilar. Surface work increased the number of principal veins from six to eight, extending cumulative mapped strike from 8 km to 11 km.
According to the company, surface exploration outlined extensions to four veins and discovered two new ones, notably the 1,150 m long Renata Vein, which will be a priority in a planned Phase II program focused on expanding higher‑grade zones and testing new targets.
Mercado Minerals (OTCQB: MRMNF, CSE: MERC) reported inaugural 3,000 metre diamond drill results from the Copalito silver-gold project in Sinaloa, Mexico, highlighted by 0.80 metres grading 9 g/t silver, 5.37 g/t gold, 1.65% lead and 10.05% zinc, or 675 g/t silver equivalent, within 3.40 metres of 403 g/t silver equivalent at the El Pilar Vein.
Step-out drilling has outlined higher-grade sub-horizontal corridors at El Pilar (about 400 metres strike by 200 metres down dip) and El Agua (about 500 metres strike by 200 metres down dip), both open along strike and partially to depth. Additional drilling confirmed vein structures at 5 Señores, El Pilar Sur, El Medio and Chente over a combined mapped strike of more than 1,900 metres. Mercado detailed QA/QC procedures and noted silver-equivalent calculations based on assumed recoveries and metal prices, with true widths yet to be defined by further drilling.
Mercado Minerals (OTCQB: MRMNF) reported new drill results from its 3,000 m diamond program at the Copalito Project in Sinaloa, Mexico.
Key intercepts include 3.50 m of 686 g/t silver equivalent and 1.20 m of 1120 g/t silver equivalent at the El Agua vein, plus broad mineralized intervals at the 5 Señores vein, where drilling has extended strike to ~800 m and vertical extent to ~125 m. Mineralization at El Agua remains open in all directions, and drilling continues on additional veins.
Mercado Minerals (OTCQB: MRMNF) signed two LOIs to acquire the San Rafael and La California silver-gold projects in the San Dimas district, Durango, Mexico. The adjacent properties total 4,617 ha with over 6.5 km of cumulative structural/vein strike.
According to Mercado, both projects can be acquired via five-year options for about $5.6 million CAD in cash, with no royalties or NSR. Reported historical underground and channel samples show high-grade silver-gold intervals, but the company’s Qualified Person classifies these results as historical and not yet independently verified.
Mercado Minerals (OTCQB: MRMNF) reported first results from a 3,000m inaugural drill program at the Copalito Project on April 29, 2026.
Highlights include 6.50 m @ 256 g/t Ag and 1.45 g/t Au (COP-26-001) including 3.45 m of 445 g/t Ag and 1.20 m of 848 g/t Ag; additional holes returned 16.70 m @ 30 g/t Ag and 7.25 m @ 89 g/t Ag. All intervals are drilled core lengths; further drilling is required to establish true widths.
