💪 GR Breaks Record

GR Silver Mining Ltd. (TSXV: GRSL) (OTCQX: GRSLF) (FRANKFURT: GPE) announces drill results from hole SMS26-04 in the SE Area of San Marcial.

Highlights:

  • 45.1m true width (TW) at 1,623 g/t Ag, from 267.85m down hole

    • including: 18.85m TW at 3,846 g/t Ag with 0.7% Pb and 2.5% Zn.

    • including: 8.25m TW at 8,579 g/t Ag with 1.6% Pb and 5.5% Zn.

High-grade silver mineralization in SMS26-04 consists of multi-stage hydrothermal breccias, subsequently overprinted by polymetallic silver-lead-zinc events.

These exceptionally high silver grades represent the "best ever" drill results from the San Marcial deposit, confirming the robust geological model, and the continuity of high-grade silver mineralization controlled by key structural features.

👏 Altamira Steps Out

Altamira Gold Corp. (TSXV: ALTA) (FSE: T6UP) (OTCQB: EQTRF) reports assay results from a second recent exploration diamond drill hole outside the Maria Bonita mineral resource in the Cajueiro District, Brazil.

Highlight:

  • 130m of 0.5g/t gold from 97m downhole.

The results from drill holes MBA036 and MBA037 suggest that the porphyry-hosted gold deposit at Maria Bonita remains open to the west and also to the north.

The distance between the two step-out holes is approximately 300 metres, and possible mineralized extensions of these blocks need to be tested both to the north and to the south.
