Matilde Extension
Blind discovery via gold-in-soil anomaly
In the first quarter of 2023, Lavras Gold announced assay results from the Matilde Extension Gold Discovery, 675 metres northeast of the Matilde Gold Discovery. It was a new blind discovery that was made by drill-testing a coincident gold in soil anomaly overlying the intersection of a northeast-southwest trending structure and an east-west trending structure. Multiple intervals of mineralization were intersected in all holes drilled at Matilde Extension, and high-grade gold, silver, and copper mineralization was encountered in three holes. Matilde Extension is unique in that the suite of sulphide minerals encountered in drilling included bornite, chalcopyrite and pyrite.
The best hole, 21MT020, intercepted three intervals of mineralization. The third intercept was the most important, as it was characterized by a thick interval of continuous mineralization featuring very high-grade gold, silver, and copper.
It assayed 10.00 metres grading 13.2 g/t gold, 22.9 g/t silver, and 0.22% copper from 345.00 metres, including:
- 5.00 metres grading 23.2 g/t gold, 42.8 g/t silver, and 0.41% copper from 347.00 metres
- a 1.00 metre sub-zone that yielded grades as high as 63.7 g/t gold, more than 100 g/t silver, and 0.63% copper from 347.00 metres.
