Red Pine Announces High Grade Intersection at The Historical Darwin-Grace Mine

Figure 1 – Overview of diamond drilling in the Nyman Shear Zone

Red Pine Exploration Inc. in 2021 and 2022, began “greenfield” exploration in the Darwin-Grace Mine area revealing a multidimensional network of mineralized shear zones that each have potential to host zones of gold mineralization.

Three major structures can now be identified in the area as:

  • the Grace Shear Zone,
  • the Nyman Shear Zone,
  • and a newly discovered, yet to be named shear zone.

Visual indicators of gold mineralization, of quartz veins containing pyrite, arsenopyrite or visible gold, have been observed in the three shear zones, and in multiple intersects in the Nyman Shear Zone (Figure 2). The intersection of 11.47 g/t gold over 2.73 meters in the Nyman Shear Zone in DG-22-317 supports the association between the positive visual indicators and gold mineralization (other intersections/holes pending).

The discovery of gold mineralization 65 meters below surface in the Nyman Shear Zone opens a large exploration target in the structure between surface and the lower levels of the former Darwin-Grace mine (Figure 1). The intersection in DG-22-317 sits at the edge of drilling in the Nyman Shear Zone area and is supporting the hypothesis that gold mined in the lower levels of the former Darwin-Grace mine could extend close to surface.

“The Darwin-Grace area has remained a target of interest for us since 2017 when 6 holes were drilled, all intersecting shallow gold mineralization of up to 57 g/t over 2.34 meters in hole DG-17-56. We have budgeted a portion of this years Phase 1 exploration program to follow up on these successes. The potential of the Darwin-Grace area to host high grade gold mineralization is well known with historical operations averaging over 11 g/t in 1934 (40 tonnes/day) with one vein averaging 571 oz/tonne from the 900 ft mark.” – Quentin Yarie, President and CEO of Red Pine Exploration.

The intersection of 11.47 g/t gold over 2.73 meters in DG-22-317 in the Nyman Shear Zone (> 3.5 km south of the Surluga deposit) is associated with the intersections of two sets of quartz veins, each vein set containing disseminated pyrite, minor chalcopyrite and spotted visible gold (Figure 2). The intersecting set of quartz veins support the multi-dimensionality of mineralization in the Darwin-Grace area. Furthermore, the lineation of intersection between the vein sets is forming an exploration target of high potential to extend the mineralization.
