Core Assets Corp. Jan. 9 announced that its 2022 field program discovered a new high-grade carbonate replacement silver-zinc-lead-copper target in the Silver Lime project area of the company's Blue property in British Columbia's Golden Triangle.

Located in the gold-rich Atlin Mining District, Blue is a 111,649-hectare (275,890 acres) land package covering high-grade skarn and carbonate replacement and porphyry prospects enriched with silver, gold, copper, zinc, and lead.

Core's 2022 exploration program at Blue included drilling two major project areas on the Blue property – Laverdiere, a prospect area in the southern part of the property that hosts three areas of outcropping skarn mineralization; and Silver Lime, a corridor of carbonate replacement deposit (CRD) copper-zinc-silver prospects about 10 kilometers (six miles) to the east.

In November, Core released preliminary results from two holes that tested CRD targets within the Silver Lime project area.

SLM22-001, drilled at the Jackie target, cut 17.19 meters averaging 28 grams per metric ton silver, 1.2% zinc, 1.4% lead, and 0.1% copper. This intercept included a 1.25-meter subsection averaging 215 grams per metric ton silver, 9.9% zinc, 8.9% lead, and 0.36% copper.

SLM22-011, drilled at the Grizzly target, which lies about 2,000 meters northwest of Jackie, cut 1.97 meters averaging 661 g/t silver, 13.2% zinc, 14% lead, 0.27% copper, and 0.22 g/t gold. This high-grade intercept included a 1.16-meter subsection averaging 1,145 g/t silver, 23.5% zinc, 23.2% lead, 0.52% copper, and 0.37 g/t gold.

The newly discovered Pete's CRD target, which lies about 1,000 meters northwest of Grizzly, shows similar high-grade potential.

"Pete's target is interpreted as numerous chimney-style massive sulphide bodies that are along trend with the Grizzly CRD and Amp targets; and, are located more than a kilometer away from the exposed Sulphide City Porphyry.

One grab sample collected from a one- by four-meter outcrop of massive sulfide mineralization at Pete's averaged 245 g/t silver, 19.6% zinc, 17.8% lead, and 0.32% copper.

Core says the carbonate replacement mineralization at Pete's is hosted in limestone and has been observed intermittently for more than 300 meters on surface.

This target is located along trend with the limestone units that extends northwest from Grizzly, through the Amp target, and to Pete's.

Samples collected from sulfide-bearing veins at Amp during project-wide prospecting and reconnaissance sampling carried out last year returned grades as high as 474 g/t silver, 7.6% zinc, 13.7% lead, and 0.37 g/t gold.

Combined, these three targets boast an average surficial grade of 143 g/t silver, 5.8% zinc, 3% lead, 0.28% copper, and 0.15 g/t gold over 117 surficial samples within a 1.57-square kilometer (0.61 square miles) zone of carbonate replacement mineralization located within a 6.6- by 1.8-kilometer (4.1 by 1.1 miles) mineralized area at Silver Lime.

"The Silver Lime porphyry-CRD project continues to produce exceptional metal grades along surface and at depth," said Core Assets President and CEO Nick Rodway.

Core is still waiting on assays from most of the 5,355 meters of drilling completed in 15 holes last year at Silver Lime. The beforementioned results from holes SLM22-001 and SLM22-011 were selected intervals that were tagged for rushed assays. Results for the balance of these and the other 13 holes are pending.

"We are currently integrating all geological data as it becomes available and the Core Assets team is eagerly awaiting drilling assay results as we continue to prepare for an aggressive, CRD focused diamond drilling campaign in 2023," said Rodway.
