Alianza Minerals Ltd. Feb. 16 announced results from the final two holes of the late 2020 drill program at its Haldane silver project about 25 kilometers (16 miles) west of Keno City, Yukon.

Located in the western portion of the historic Keno Hill Mining District, the 8,579-hectare (21,200 acres) Haldane project is the site of a historical mine that produced roughly 24.7 metric tons of hand-sorted ore averaging 3,102 grams per metric ton (99.7 ounces per metric ton) silver and 59% lead on the south side of Bighorn Creek veins. From 1926 and 1927, a vein on the north side of Bighorn Creek produced 2.1 metric tons of hand-sorted ore averaging 4,602 g/t (148 oz/t) silver and 57.9% lead.

In late October, Alianza launched a drill program that included the completion of two holes in each of the West Fault and Middlecoff targets at Haldane.

West Fault is a new zone located at the northwest end of the Mount Haldane Vein System, a complex fault and vein system about 2,500 meters southeast of Bighorn.

The West Fault discovery hole, drilled in 2011, cut 2.2 meters (roughly 1.2 meters true width) averaging 320 g/t silver.

Alianza's late 2020 drilling cut wider and higher-grade silver at West Fault.

Hole HLD20-19 cut 16.15 meters (8.7 meters estimated true-width) averaging 311 g/t silver from a depth of 246.9 meters, include 3.3 meters (1.8 meters estimated true-width) averaging 818 g/t silver.

"The breadth and grade of silver mineralization encountered at the West Fault indicates that this target, and the Haldane project as a whole, has the potential to host silver deposits comparable to others in the greater Keno District," Alianza Minerals President and CEO Jason Weber said. "The West Fault will be a primary target of our 2021 drilling campaign."

The latest batch of results are from Middlecoff, a vein about 1,500 meters south of West Fault.

Hole HLD20-21 cut 6.75 meters (three meters estimated true-width) averaging 81 g/t silver from a depth of 180.6 meters, including 0.89 meters (0.4 meters estimated true-width) averaging 342 g/t silver.

"The Middlecoff drilling has shown that the structure and mineralization is continuous to the south," said Weber. "As we learn more at the Middlecoff, it is apparent that the host structure and vein system is productive, and we will continue to explore to the south and at depth for thick, high-grade silver intercepts as we have now seen at West Fault."

Alianza is planning for a second phase of the drill program, which is expected to get underway in April.

West Fault and Middlecoff are expected to be among the targets tested during the spring drilling.
