Wide Silver Hits Extend Mineralisation By 100m
GR Silver Mining Ltd.(TSXV: GRSL) has reported that drill results have extended the high-grade silver mineralisation 100 m to the north along strike in the San Juan Vein in Mexico.
Additionally, a wide, up to 65 m continuous silver mineralised zone, is delineated on the footwall of the Yecora Vein, defining shallow wide mineralised 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 in Sinaloa, Mexico.
The latest results integrate drill holes obtained from the vompany’s current drill programme 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.
President and CEO, Marcio Fonseca, said the high-grade silver mineralisation encountered in the San Juan Vein confirms continuity of the mineralisation close to surface, 100 m to the north along strike, and also correlates with previously identified high-grade mineralisation at depth.
“We are very pleased to report additional results from the Company’s 2021 drilling of the San Juan Area, which in combination with historical drill results, significantly extend shallow high-grade silver vein structures,” Mr Fonseca said.
“The results also identify wide mineralisation adjacent to existing high-grade silver veins, defining a large epithermal system to support the maiden resource delineation underway for the San Juan Area.
“These results highlight the potential of three of the six veins in the San Juan Area to host a shallow high-grade resource. The remaining veins at San Juan provide an opportunity for possible future resource estimations.”
Mr Fonseca said 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.
He said this type of wide mineralisation, 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 mineralised 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 mineralisation 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 programme 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 Q2/2021
- Surface drilling on three additional veins; San Francisco, La Odisea and Loma Dorada, to further delineate extensions to the known mineralisation.
