Mercado Minerals Ltd. (MERC:CSE; MRMNF:OTCQB; M2R:FSE) announced that it has signed two letters of intent (LOIs) to acquire the adjacent San Rafael and La California silver-gold projects in the San Dimas mining district of Durango, Mexico. According to the company, the acquisitions would create a district-scale land package covering 4,617 hectares with more than 6.5 kilometers of cumulative strike potential in the Sierra Madre Occidental.
The company said the two projects are located in the San Dimas mining district, where past production through December 2024 was estimated at more than 766 million ounces of silver and more than 11.1 million ounces of gold. Mercado stated that the properties span a northwestern-trending structural corridor along the Sierra Madre Occidental silver-gold belt.
Under the terms of the LOIs, Mercado may acquire a 100% interest in both projects through five-year option agreements requiring total cash payments of approximately US$5.6 million. The company stated that larger payments are weighted toward the later years of the agreements and that no royalties or net smelter return royalty payments are associated with the transactions.
"This is exactly the type of opportunity Mercado is looking for," Chief Executive Officer Daniel Rodriguez said in the company news release. "We are now working towards building a truly district-scale presence with kilometers of cumulative vein strike length and numerous highly compelling targets."
The San Rafael project comprises five concessions totaling 1,004 hectares located approximately 154 kilometers west-northwest of Durango. Mercado said the property contains a structurally controlled low-sulphidation epithermal gold-silver system, with the San Rafael fault structure identified along 4.5 kilometers of strike within the concession boundaries. The company reported that historical underground workings include four levels totaling about 400 meters of development. Historical surface work conducted in 2005 and 2008 included 161 samples, with a highlighted channel sample returning 2.15 meters grading 241 grams per tonne silver and 10.1 grams per tonne gold. Mercado also noted that a 2014 drill program completed by Servicio Geologico Mexicano intersected 0.46 meter grading 180 grams per tonne silver.
The company stated that its qualified person has not independently verified the historical sampling or drill results from San Rafael and that the information is being treated as historical in nature until verification work is completed.
The La California project comprises five concessions totaling 3,613 hectares and is located adjacent to San Rafael. Mercado said the property hosts a low-sulphidation epithermal gold-silver system traced along more than two kilometers of outcrop, with vein widths ranging from two meters to 10 meters. The company reported that the historical underground mine operated from 1912 to 1922 and included an on-site mill that reportedly processed between 20 and 40 tons of material per day.
According to Mercado, the most recent exploration work at La California was conducted in 2000 and included 15 grab samples. A highlighted channel sample returned 2.50 meters grading 380 grams per tonne silver and 1.28 grams per tonne gold. The company stated that La California has not received systematic modern exploration.
Mercado noted that its qualified person has not independently verified the historical sampling results from La California and is treating the information as historical pending future verification work.
Advancing Multiple Exploration Programs Across Mexico
In addition to the proposed acquisitions, Mercado stated in its April 2026 corporate presentation that it is fully funded for its current drill program and upcoming exploration activities in 2026.
At the Copalito project in Sinaloa, the company reported that an inaugural 3,000-meter diamond drill program is underway. Mercado said the program is designed to test extensions of known veins, conduct infill drilling, evaluate targets at depth, and drill newly identified targets. The company noted that previous operators completed 81 diamond drill holes between 2020 and 2021 and that drilling has tested approximately 60% of the known strike length of the veins to an average depth of 100 meters.
Mercado stated that the 2026 drill campaign is planned to test four high-priority targets at 5 Señores, El Agua, and La Chivas. The company also reported that ongoing structural interpretation is being used to refine drill targeting with the objective of testing thicker and higher-grade vein segments. In addition, Mercado identified potential exploration targets along northwesterly vein extensions supported by completed drone magnetic and LiDAR surveys.
