Sierra Madre Gold and Silver Ltd. announce the results of four additional drill holes from the Phase I drill program at its La Tigra Gold/Silver Project in the State of Nayarit, Mexico.
- Length-weighted averages from uncut assays
- Intervals reported are hole lengths with true width estimated to be 90% or greater
- *Gold silver ratio used to calculate AuEq is 75 g/t Ag to 1 g/t Au
- 0.4 g/t AuEq external cut off
Gregory K. Liller, Executive Chairman and Chief Operating Officer commented “The drilling program at La Tigra continues to deliver strong results with some intercepts being wider than initially expected. These results continue to expand on the positive results to date at La Tigra.”
The Phase I drilling program at La Tigra was designed using the data acquired from extensive surface mapping, sampling and trenching programs. This work has defined a 3.5 km long structural corridor with stacked northwest striking structures. Results for the first three holes from this Phase 1 program were released on May 24, 2022.
The structures at La Tigra dip at 40⁰ to 45⁰ and holes 1 and 2 were drilled at -45⁰ and hole 3, -53⁰. As such the true width of the intersections are approximately +90% of the intersected length.
The following map shows the locations of the holes.
About Sierra Madre
Sierra Madre Gold & Silver (TSX.V:SM) is a precious metals development and exploration company, focused on evaluating the potential of restarting the La Guitarra Mine in the Temascaltepec mining district, Mexico, and the exploration and development of its Tepic and La Tigra properties in Nayarit, Mexico. The La Guitarra Mine is a permitted, past-producing underground mine which includes a 550 t/d processing facility that operated until mid-2018.
The +2,600 ha Tepic Project hosts low-sulphidation epithermal gold and silver mineralization with an existing historic resource. La Tigra, located 148 km north of Tepic, has been mined historically; Sierra Madre´s maiden 2022 drill program at the site intercepted shallow mineralization.
Sierra Madre´s management has played key roles for managing exploration and development of more than 22Moz gold and 600Moz silver in combined reserves and resources. Sierra Madre´s team of professionals has collectively raised over $1B for mining companies.
