Grande Portage drills 9.87 g/t gold over 3.39 metres at Herbert, Alaska

Grande Portage Resources Ltd. [TSXV-GPG; OTCQB-GPTRF; FSE-GPB] reported results from three more diamond drill holes drilled at the Herbert gold project, southeast Alaska.

Highlights: After drilling four holes from Pad M, the rig was moved 285 meters eastward where four more holes were drilled from Pad P. The company confirms that all Pad P holes successfully targeted the eastern extensions of the Goat vein between 200 and 300 metres below surface. These holes tested an area of the eastern Goat vein which previously had indications of strong gold mineralization but only had sparse drilling. The three holes for which assay results have been returned substantiate that this is a significant gold-bearing region of the Goat and is expected to have a positive impact on the company’s future mineral resource calculation.

The Goat vein structure was the target and was intersected in all four holes from this pad. DDH23P-3 also extended southward past the Goat vein where it intersected a well mineralized section of the Sleeping Giant vein. Sample analyses from 23P-3 are pending and will be announced in due course.

DDH23P-1 intersected 1.10 metres of 7.66 g/t gold in the Goat vein. This hole was approximately 36 metres below DDH20T-11 (24.0 g/t gold over 2.1 metres) and 56 metres west of DDH21P-4.

DDH23P-2 intersected 2.83 metres of 7.753 g/t gold in the Goat vein. This hole was approximately 86 metres below DDH23P-1. This intercept was approximately 15 metres east of DDH21P-1 and 27 metres above DDH20P-1 (9.79 g/t gold over 0.8 metres). This intersect occurs in a 10-metre shear zone and contains a 1.08-metre section which assayed 15.8 g/t gold in a silicified and micro-brecciated vein riddled with thin sulfide-rich seams in a hydrothermally altered quartz diorite.

DDH23P-4 intersected 3.39 metres of 9.871 g/t gold including a 1.08-metre interval of quartz vein assaying 30.8 g/t gold. This hole was approximately 47 metres below DDH21P-3 (3.8 g/t gold over 0.9 metres). At the elevation of this intercept the Goat vein now has approximately 900 metres of strike length from west to east.

The success of the 2023 drilling from the P Pad is highly encouraging because it demonstrates that strong gold mineralization can be found in the east-west Herbert vein structures the full distance between the western and eastern boundary faults which effectively terminate the veins. The depth of the veins remains open, but strong gold values have been intersected in DDH21Q-4 (0.92 meters of 18.93 g/t gold) at 600 metres below the surface in the company’s deepest drilling, which indicates that the company’s resource is only constrained by the major east and western boundary faults.

After completing drilling at the Pad P, the company moved the rig to Pad BB, which is the easternmost drill pad on the property, and completed one hole targeting the Goat vein and the Sleeping Giant vein. Drilling results are still pending.

Past drilling over many years has confirmed that the Herbert gold project is a high-grade deposit. The chief primary gold-bearing veins at the Herbert gold project are strong, persistent and extend from the Western boundary fault to the Eastern fault, a distance averaging nearly 1 km. Strong gold mineralization has been identified almost everywhere along these structures, both laterally and to the deepest limits of drilling over the last number of years. Much of the shallower portions of the veins have been tested with good to superb results.

Ian Klassen, President and CEO, reports that, “Drilling this season certainly assists to fill in certain gaps within the established resource and adds to the confidence leading into a new resource estimate that will include the added drilling completed over the recent three-year period. Extending the higher-grade Goat vein to the east with these three more material intersections is great news.”

The Herbert Gold discovery is situated approximately 25 km north of Juneau, Alaska. The company holds a 100% interest in the Herbert property. The Herbert Gold property system is open to length and depth and is host to at least six main composite vein-fault structures that contain ribbon structure quartz-sulfide veins. The project lies prominently within the 160km long Juneau Gold Belt, which has produced over seven million ounces of gold. The company’s updated NI#43-101 Mineral Resource estimate reported at a base case mineral resources cut-off grade of 3.0 g/t Au and consists of an indicated resource of 1,196,800 ounces of gold averaging 10.23 g/t Au (3,637,000 tonnes); and an inferred resource of 325,900 ounces of gold averaging 8.91 g/t Au (1,138,000 tonnes), as well as an Indicated resource of 686,700 ounces of silver averaging 5.87 g/t Ag (3,637,000 tonnes); and an inferred resource of 169,300 ounces of silver averaging 4.63 g/t silver (1,138,000 tonnes).
