GR Silver Mining Ltd. announced that it has now completed the acquisition of 100% of Marlin Gold Mining Ltd. from Mako Mining Corp. Marlin owns 100% of Oro Gold de Mexico, S.A. de C.V. that owns the past-producer La Trinidad open pit Au mine, that ceased operating in 2019, and 12 highly prospective concessions totaling 107,392.5 ha located adjacent to GR Silver's existing portfolio of properties. This gives the company control of 75 km of prospective trend with known mineralization including three zones and over 24 shallow gold-silver old workings, which are all strategically located on the western edge of the prolific Sierra Madre Occidental gold-silver belt in Sinaloa, Mexico. The acquisition of Marlin is the third significant transaction completed by GR Silver Mining. In accordance with the Company's long-term strategy, GR Silver Mining now controls two past-producing mines (Plomosas and La Trinidad) that are fully permitted for future production, a current resource at San Marcial, as well as the most prospective Ag-Au exploration ground in the Rosario Mining District. This is the first time in modern history that one company has held all of these key assets under single ownership, whereas previously each had been controlled by separate companies. GR Silver Mining continues to achieve significant corporate milestones and to deliver on its stated objective to continue to add shareholder value. The main exploration focus on the 12 Marlin concessions has historically been on La Trinidad (Taunus Pit) which produced over 164,000 oz of gold until its closure in 2019. Another advanced stage project within the acquired portfolio is the Cimarron Project, located to the NW of La Trinidad. A number of targets have been identified at Cimarron including Calerita, El Prado, Huanacaxtle, Betty and Veteranos. The Calerita gold-(copper) deposit at Cimarron, is the only target to have been drilled to date, and represents an intrusive related gold deposit for which Marlin released a historical gold resource estimate in 2011. Extensive regional geochemical datasets were compiled by Oro Gold covering a large portion of the concessions with over 700 stream sediment samples, 500 rock and channel samples, as well as over 9,000 soil samples. Key exploration targets that were generated and initially drilled are aligned along one of three highly prospective NW-SE trending corridors, with this 12 km long section connecting the Taunus Pit with the San Carlos, Colinas, San Miguel, Guayabo and San Cristobal targets. A total of 40,500 m of diamond, RC and sonic drilling were completed by Oro Gold. This extensive drill database will be incorporated into GR Silver Mining's growing regional database to further advance the company's exploration model. The La Trinidad concessions together with the Cimarron concession ("core concessions") represent areas for future exploration in the Rosario Mining District. During the 2020 due diligence period for this acquisition, GR Silver Mining identified an area of the La Trinidad concession wedged between the company's two flagship projects - San Marcial and Plomosas - as a key area to investigate structural links between mineralization in the two projects. The area, known as the "GAP Area", is a 6 km2 section of the La Trinidad concession connecting the NW-SE mineralization trends at both San Marcial and Plomosas. Over 2,000 rock samples were collected on grid lines and analysed by pXRF for multi-element geochemistry. Two anomalous NW-SE trending Au-Ag mineralized zones, along with a number of shallow underground workings, were identified which connect with known mineralized vein and breccia structures in the San Marcial and the Plomosas concessions. Preliminary channel and chip sampling was completed, but the structures remain to be drill tested. GR Silver Mining is currently organizing and evaluating the data generated from the historical regional datasets, as well as specific targets that were previously drilled. The Company believes that there is significant Au and Ag exploration potential in the La Trinidad concession, with more than 24 known and under-explored mineral occurrences, as well as historic workings.
