The 2021 exploration program at Herbert Gold included 8,150 meters of drilling in 19 step out and infill holes.

Grande Portage Resources Ltd. March 29 announced the remaining drill results from its summer and fall 2021 drill program at the Herbert Gold project in Southeast Alaska. These results will be added to the company's NI 43-101 mineral resource estimate.

According to a calculation completed in May of last year, Herbert Gold hosts 3.64 million metric tons of indicated resource averaging 10.23 grams per metric ton (1.2 million oz) gold and 5.87 g/t (686,700 oz) silver; plus 1.14 million metric tons of inferred resource averaging 8.91 g/t (325,900 oz) gold and 4.63 g/t (169,300 oz) silver.

The exploration program was completed in late October 2021, with the drill holes announced from infill and expansion drilling at Herbert.

"These results have continued to expand our high-grade zones in the Goat, Main and Deep Trench veins into previously undrilled areas," said Grande Portage Resources President and CEO Ian Klassen. "Additionally, infill drilling shows potential for the Sleeping Giant to expand to the west as well as to depth, and for the higher-grade zones within the Main vein to expand to the west."

Highlights from these results include:

2.13 meters averaging 15.42 g/t gold in hole 21Q-4 at Sleeping Giant. This intersection has significant quartz, shearing, and hydrothermal alteration and demonstrates strong potential for the development of additional high-grade shoots.

0.92 meters averaging 20.9 g/t gold in hole 21Q-4 on the Main vein. This intersection is at the deepest limits of drilling to date on the Main vein and is open to depth and eastward. This intercept is 600 meters below the surface and is 125 meters east of a high-grade intersection in 20T-7.

1.07 meters averaging 85.74 g/t gold in hole 21Q-6. This intersection is approximately 20 meters into the hanging wall of the Goat vein and contains visible gold.

According to Grande Portage, the three major veins are quite pervasive and predictable with strong surface expressions due to erosion of fractured and hydrothermally altered quartz diorite associated with the major East-West striking mineralized faults.

Furthermore, the company added that in addition to these major structures, a complex system of splits, transverse veins, and satellite veins exist which often attain significant size and grade in themselves and will be major contributors to the overall gold resources in the Herbert system.

Finally, the Sleeping Giant and North Strand of the Main vein are prime examples of this fact, says Grand Portage. Very high-grade zones are often encountered due to structural complications introduced during tectonism and mineralization.

"We look forward to increasing these zones during our upcoming, fully funded 2022 drill season," finished Klassen.
