GR Silver Mining Ltd. (?GR?Silver Mining? or the ?Company?)?to report drill results that extend the high-grade silver mineralization 100 m to the north along strike in the San Juan Vein. Additionally, a wide, up to 65 m continuous silver mineralized zone, is delineated on the footwall of the Yecora Vein, defining shallow wide mineralized zones to be included in the upcoming maiden resource estimate at San Juan. Both veins are part of the vein system of the San Juan Area of the Plomosas Silver Project (?Plomosas Project?) in Sinaloa, Mexico. The results contained within this news release integrate drill holes obtained from the Company's current drill program with the existing historic drilling data to support the upcoming maiden resource estimates on the Plomosas Project. They represent intersections in two of the six veins already delineated in the San Juan Area. The high-grade silver mineralization encountered in the San Juan Vein confirms continuity of the mineralization close to surface, 100 m to the north along strike, and also correlates with previously identified high-grade mineralization at depth. The broad interval of silver mineralization on the footwall of the Yecora Vein represents the discovery of a much larger footprint than initially interpreted for this epithermal vein system, supporting potential open pit-amenable zones. This type of wide mineralization, hosted in a hydrothermal breccia at Yecora, has geological similarities with high-grade silver-gold mineralization drilled 100 m along strike and previously reported. Ground geophysical data indicates the presence of large bodies at depth, possibly related to the wide-spread silver mineralized zones at San Juan. Surface diamond core drilling is ongoing at the other veins within the San Juan Area, particularly in the La Colorada Vein. GR Silver continues to delineate high-grade, shallow silver-gold mineralization at the La Colorada Vein. The La Colorada Vein represents a NW continuation of the Yecora Vein, in an area with a series of shallow old workings, and where the vein system has the potential to be extended at least another 1 km along strike. The shallow core drilling program underway at the San Juan Area will integrate three vein zones; San Juan, Yecora and La Colorada, with a combined total strike length of 2 km into an initial maiden resource estimate. Additional veins located in the San Juan Area, which include San Francisco, Loma Dorada and La Odisea, will be the subject of additional diamond drilling in 2021, following the completion of the maiden resource estimation, intending to continue the Company's identification of new resources in the Plomosas Project. Based on the results to date, the Company intends the following: To complete the remaining 1,600 m of surface drilling at the San Juan Area by May 2021, covering the San Juan, Yecora and La Colorada Veins; To complete a maiden NI 43-101 mineral resource for the San Juan Area and a maiden NI 43-101 resource for the Plomosas Mine Area by the end of second quarter of 2021; and Surface drilling on three additional veins; San Francisco, La Odisea and Loma Dorada, to further delineate extensions to the known mineralization. The Plomosas Mine Area and San Juan Area represent two independent areas at resource estimation stage. The Plomosas Mine Area has a current strike length of 600 m and the San Juan Area is 2 km in length. The Company is completing two separate resource estimates which will be part of the combined maiden NI 43-101 report for the Plomosas Project. Both areas have a geological footprint similar to the San Marcial Project, 5 km to the south. At the San Marcial Project the company has estimated an initial NI 43-101 resource of 29 Moz Ag (Indicated) and 10 Moz Ag (Inferred)2, on the initial 500 m strike length. The San Marcial NI 43-101 resource is part of a larger 6 km trend under exploration, including a current ground geophysics survey and diamond drilling planned for later in 2021. The integration of the Plomosas Project and the San Marcial Project, together with the recent acquisition of the Trinidad Project, provides the Company with full control of three major structural corridors on the eastern half of the Rosario Mining District, representing a total of 75 km of strike length. During 2021, GR Silver Mining will continue to explore new mineralized zones, close to surface, within these projects, providing potential for additional resource growth.
