Discovery Alaska Ltd (ASX:DAF) has confirmed broad lithium mineralisation during re-sampling of historic drill core from Coal Creek Lithium Prospect within the Chulitna Project in Alaska, USA.
The company conducted a detailed work program of selected priority core, comprising core logging, core cutting, core photography, core sampling and laboratory analysis works to determine the lithium potential of the prospect.
Standout lithium intersections from the laboratory analysis work include:
- 16 metres at 0.19% lithium from 126.5 metres;
- 10.97 metres at 0.18% lithium from 84.7 metres; and
- 27.65 metres at 0.16% lithium from 169.6 metres.
Moving forward, accessibility, quality and quantity of Coal Creek drill core allow DAF to advance further exploration works, with the aim to establish a JORC lithium resource.
The Chulitna Project comprises 199 square kilometres of granted mining claims containing multiple prospect targets for varying commodities, including lithium, gold, silver, copper, tin and base metals.
“Significant broad zones”
Discovery Alaska director Jerko Zuvela said: “The company is excited with the first-stage laboratory analysis results confirming significant broad zones of lithium mineralisation at our Coal Creek prospect, with potential for strike and depth extensions.
“These initial results provide encouragement for continued exploration works.
“We look forward to realising the lithium potential and advancing works toward delineating a maiden JORC resource at our Coal Creek prospect, strategically located close to the major Parks Highway and the State-owned Alaska railroad.”
Forward plan
DAF will continue to expedite lithium exploration and test-work – including the remaining prospective drill core at Coal Creek.
Positive lithium analysis results obtained at the bottom of several drill holes indicate the potential for further lithium-bearing zones remaining open at depth into the aplite porphyry.
The company will consider the potential to expand the sampling program using the current historic drill holes and associated works conducted (ie core logging) and sampling the deeper sections of core where the aplite porphyry was observed.
Furthermore, DAF has identified additional nearby granitic intrusions prospective for lithium, with the possibility to explore whether these intrusions are connected beneath the surface material.
