StrikePoint Gold's Porter project covers historic high-grade silver mines on Mount Rainey above Stewart, a mining town at the southern tip of British Columbia's Golden Triangle.

StrikePoint Gold Inc. Jan. 21 reported that 2020 sampling has discovered new high-grade silver veins and extensions of already known veins at the company's Porter silver property on Mount Rainey overlooking Stewart, a town at the southern tip of British Columbia's Golden Triangle.

"We are clearly looking at a high-grade silver vein system located within view of the mining town of Stewart, BC," said StrikePoint Gold CEO Shawn Khunkhun.

Early 20th century mining of the vein systems that run through Mount Rainey produced roughly 2.2 million ounces of silver from 27,123 metric tons of ore averaging 2,542 grams per metric ton silver.

StrikePoint believes the ore mined from Prosperity-Porter Idaho and Silverado, the historic mines on Mount Rainey, could represent opposite ends of a larger mineralized system that extends for 2,350 meters through the mountain. Recent glacial retreat has exposed more of the ground between these past producing mine sites, making it easier to explore for a connection.

During 2020, geologists completed detailed mapping and sampling in areas of steep terrain and extensive ice recession near the historic Silverado mine on the west side Mount Rainey and at the Prosperity-Porter Idaho mines area on the east side. Strikepoint says there are no records of previous mapping or sampling of veins in these areas.

This surface exploration program uncovered massive to semi-massive pyrite-galena-sphalerite-chalcopyrite polymetallic veins in a shear zone. Assays from the 2020 sampling returned grades as high as 3,840 g/t (111.9 ounces per metric ton) silver, 5.56% zinc, and 12.45% lead.

Significantly, on the Silverado Mine side of Mount Rainey, sampling identified extensions of the historically mined #2 and #4 veins.

One surface sample of vein #2, which was collected north of the historical adit, returned 1,170 g/t (37.6 oz/t) silver, 0.53% zinc, and 0.86% lead.

One sample of the new surface expression of vein #4, also collected north of the historical adit, returned 1,385 g/t (44.5 oz/t) silver, 0.43% zinc, and 4.1% lead.

Meanwhile, on the Prosperity & Porter Idaho side of Mount Rainey sampling discovered new veins.

This includes a new 250-meter mineralized trend that runs parallel to the past producing Prosperity veins. One sample of the newly discovered vein returned 240 g/t silver, 0.22% zinc, and 1.52% lead; and another sample returned 112 g/t silver, 0.9% zinc, and 0.11% lead. StrikePoint said this new vein is located 130-meters west of the historical adit and the terrain along strike to the south and west of the new trend remains open and highly prospective for additional exploration work.

A new surface expression of the Prosperity vein was also outlined about 30 meters south of the historical portal for tunnels B and C, strengthening the structural understanding of the mineralization. One sample collected from this area returned 182 g/t silver, 1.81% zinc, and 1.13% lead.

Confirmation of the historical Prosperity vein itself returned 1,525 g/t (49 oz/t) silver, 0.18% zinc, and 12.45% lead; and 3,840 g/t silver, 0.09% zinc, and 2.37% lead.

One sample of the Wake vein returned 1,275 g/t silver, 5.56% zinc, and 0.23% lead.

Sampling of a 200-meter extension of the D-vein mineralized trend to the north returned 76 g/t silver, 0.58% zinc, and 0.98% lead. This extension narrows the gap in mineralization between the past-producing Prosperity-Porter-Idaho and Silverado mines.

"Our exploration work on the Porter property continues to progress, connecting the historic high-grade, direct shipping past producing mines at Prosperity-Porter Idaho on the east side of Mount Rainey with the Silverado Mines on the west side, located over two kilometers away," said Khunkhun. "With a strong treasury, we look forward to an aggressive drill program in 2021 with the objective of connecting these two famous operations."
