818 g/t SILVER over 1.78 m true width intersected @Haldane Alianza Minerals intersects 818 g/t silver over 1.78 m true width at Haldane Project, Keno Hill District, Yukon - Intersection within an 8.72 m wide fault/vein zone averaging 311 g/t silver
- West Fault target open in all directions
- Step-out drilling at West Fault and Middlecoff planned for spring program
Vancouver, BC, January 28, 2021 - Alianza Minerals Ltd. (
TSX-V: ANZ, OTC: TARSF) (“
Alianza” or the
“Company”) is pleased to report results from the Phase One diamond drilling program at the Company’s wholly owned Haldane Silver Project located in the historic Keno Hill Mining District of Yukon Territory. Holes HLD20-18 and HLD20-19 targeted the West Fault, with both holes intersecting silver mineralization including a core length of
16.15 m (estimated true width 8.72 m) averaging 311 g/t silver, 0.89% lead and 1.13% zinc (390 g/t silver-equivalent*). This includes a high-grade core of
818 g/t silver, 3.47% lead and 1.03% zinc (980 g/t silver-equivalent) over 3.3 m (1.78 m estimated true width). The 8,579-hectare Haldane Project is located 25 km west of Keno City, Yukon in the western portion of the Keno Hill Mining District. Alianza completed the late season drilling program in early December 2020. Results from the remaining two holes of this program testing the Middlecoff target are pending.
The West Fault structure, as interpreted from surface geology and historical drilling, is over 1,750 m in strike length. Drilling to date has successfully intersected the West Fault over a fraction of this strike length and the target remains open in all directions. The high-grade results from HLD20-19 now allow for additional vectoring along possible high-grade ore-shoot orientations.
“
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
,” stated Jason Weber, P.Geo., President and CEO of Alianza.
“With these results, the West Fault is proving to be a robust structure with high-grade silver over substantial widths. The West Fault will be a primary target of our 2021 drilling campaign.” The 2020 program at the West Fault was designed to follow up on a 2011 intersection of 320 g/t silver, 1.12 g/t gold,0.67% lead and 0.86% zinc over 2.20 m obtained by a prior operator
. HLD20-19 intersected 16.15 metres of heavily broken and faulted mineralization in the vein structure and adjacent footwall crackle breccia. HLD20-19 intersected the target structure 39 m along strike and 55 m down dip of the 2011 intersection. Much of the structure is heavily fractured and broken, but fragments of sulphide vein (galena, sphalerite +/- sulphosalts) in an iron-manganese carbonate matrix are evident. This is most apparent in a 4.48 m (estimated true width) intersection averaging 444 g/t silver, 1.54% lead, and 1.34% zinc.
HLD20-18 tested the West Fault 18 m along strike and 27 m down dip of the 2011 hole. HLD20-18 returned 96 g/t silver, 0.15% lead and 0.73% zinc over 3.73 m (estimated true width) from a well-defined structure dominated by iron-manganese carbonate gangue.

Analytical values have been rounded.
*Silver-equivalent values are calculated assuming 100% recovery using the formula: ((20 * silver (g/t) / 31.104) + (1650 * gold (g/t) / 31.104) + (0.90 * 2204 * lead %/100) + (1.10 * 2204 * zinc %/100)) *(31.1035 / 20). Metal price assumptions are US$20/oz silver, US$1650/oz gold, US$0.90/lb lead and US$1.10/lb zinc.
