Located 16 miles north of Juneau, the Herbert Gold project is an exploration stage, high-grade, gold-mineralized mesothermal quartz vein system in the historic Juneau Gold Belt of Southeast Alaska.

Grande Portage Resources Ltd. March 15 announced it has signed a drilling agreement with NASCO Industrial Services and Supply for its upcoming 2023 diamond drill program at the Herbert Gold project in Southeast Alaska.

Hoping to make up for its 2022 program, Grande Portage has shifted its most prospective targets planned from the year before to this year.

"Our 2022 began late due to unforeseen contractor and supply chain delays," Grande Portage Resources President and CEO Ian Klassen said in November. "This, coupled with unseasonably poor and foggy weather, further interrupted the company's original drill plan."

Despite these setbacks, the company was able to drill with five holes from pad AB, which is farther north than any previous drill pads, targeting deeper projections of the Goat, Sleeping Giant, Ridge, and Main veins.

One hole, 22AB-4, cut all three of these veins. These intercepts include –1.21 meters averaging 3.22 grams per metric ton gold from 472.7 meters and 1.15 meters averaging 4.03 g/t gold from 473.9 meters (Goat); 0.73 meters averaging 6.08 g/t gold from 597.9 meters (Sleeping Giant); and 0.8 meters averaging 3.3 g/t gold from 740.7 meters (Main).

Past drilling over several years has confirmed that the Herbert Gold project is a high-grade deposit with the primary gold-bearing veins extending from the Western boundary fault to the Eastern fault, a distance averaging nearly 1,000 meters.

According to a 2021 calculation, 3.64 million metric tons of indicated resource averaging 10.23 g/t (1.2 million ounces) 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 has been outlined in this area.

NASCO, whose clients include Hecla Mining, First Majestic Silver, and Rio Tinto, has been engaged by Grande Portage to drill up to 20,000 feet at Herbert Gold. This program is expected to begin within 90 days and will consist of one rig utilizing up to six pads to drill approximately 15 holes.

"We are very excited to start this season's drill program. The 2023 drill program will continue to test a mix of infill and new targeted areas," said Klassen. "We have prioritized and will target many geologically promising high value targets at the Main, Goat, Deep Trench, Ridge, and Sleeping Giant veins from multiple locations. Our geologists have gone to great lengths to ensure that this upcoming program targets the type of success we have enjoyed over many years building the high-grade Herbert Gold project."
