Alien Metals reports final assay results at Elizabeth Hill
Published by Jessica Casey,
Global Mining Review,
Alien Metals Ltd, a global minerals exploration and development company, has reported the final assay results from the inaugural drilling programme at the high-grade Elizabeth Hill Silver Project in the Pilbara Region of Western Australia. The drill programme consisted of diamond and reverse circulation (RC) drilling for a total of 1991 m. The company has received the final results from the 15 RC drill holes completed during the second phase of the inaugural drilling programme, which builds on the results of the initial phase announced on 27 January 2022.
- Further high grade silver assays have been returned from the Elizabeth Hill RC drilling programme, including:
- Drillhole AMEHRC009: 8 m at 4233 g/t silver (Ag) (149 oz/t Ag) from 66 m.
- Drillhole AMEHRC012: 2 m at 1550 g/t Ag (55 oz/t Ag) from 108 m, which represents a potential new mineralised zone 400 m south of the Elizabeth Hill mine along the Munni Munni Fault.
- Additionally, encouraging base metals assay results:
- Drillhole AMEHRC005: 24 m at 0.19% copper (Cu), 0.17% nickel (Ni) and 150 g/t cobalt (Co) from 78 m, including 10 m at 0.25% Cu, 0.26% Ni and 218 g/t Co.
- Drillhole AMEHRC004: 8 m at 0.83% Pb and 0.13% Zn from 48 m, including 4 m at 1.35% lead (Pb), 0.2% zince (Zn).
- Drillhole AMEHRC006: 26 m at 0.48% Pb from 8 m, including 6 m at 1.95% Pb.
- Interpretation of these RC results is ongoing but suggests a potential repeat of the Elizabeth Hill deposit along the Munni Munni Fault.
- Planning for follow-up drilling is underway to further test the potential repeat mineralisation and the larger envelope present at Elizabeth Hill.
Bill Brodie Good, CEO and Technical Director of Alien Metals, commented: “The final assay results provide further confirmation of the exceptionally high-grade tenor of the silver mineralisation at Elizabeth Hill, with additional excellent intersections within the historic orebody. The intersection within hole AMEHRC0012, which was drilled on the south of the orebody, is significant as it encountered high-grade mineralisation at a depth where we always thought there might be a possible repetition of the Elizabeth Hill silver orebody.
“It is also encouraging to see the presence of wide intersections of base metals in the eastern mafic units which run parallel to the Elizabeth Hill silver deposit in the final batch of assay results. This may present as significant base metals VMS style target. The company is currently working with our technical consultants to gain a better understanding of this target ahead of a follow-up exploration programme.”
The silver mineralisation associated with the historically defined orebody is both significant and extremely high-grade. The shallow southerly dip of this orebody is confirmed here and the company has also shown that there remains significant high grade un-mined ore in both the oxide and top of the fresher orebody to at least 76 m vertical depth. Ongoing review of these results is in progress by the company to plan the next phase of work.
A significant silver intersection in hole AMEHRC012 returned 2 m at 1550 g/t Ag (47 oz/t Ag) from 108 m depth. The hole was targeting a possible southern repeat silver mineralised system and, lying close to the Munni Munni fault, the location is highly encouraging to the company and a review will be undertaken to follow up on this potential discovery. The QA/QC of the laboratory results were all within acceptable levels however the company has requested certain samples in and around the high grade intersection in hole AMEHRC012 to be re-analysed just to add extra confidence before possible follow up drilling is carried out on this target to verify if there could be a wider intersection here or if this represents a narrow but significant off-shoot from a larger mineralised system to be targeted.
The presence of significant copper, nickel, cobalt, zinc and lead found in the mafic units associated with the Munni Munni intrusion are also highly encouraging. Highlights included: 24 m at 0.19% Cu, 0.17% Ni and 150 g/t Co from 78 m (including 10 m at 0.25% Cu, 0.26% Ni and 218 g/t Co) in drillhole AMEHRC005, 8 m at 0.83% Pb and 0.13% Zn from 48 m (including 4 m at 1.35% Pb, 0.2% Zn) in drillhole AMEHRC004, and 26 m at 0.48% Pb from 8 m (including 6 m at 1.95% Pb) in drillhole AMEHRC006.
With these encouraging results the company plans to review in more detail all historical polymetallic assays from all historic drilling across the tenement in combination with this new data to define the next stage of exploration of this target as it may represent a larger polymetallic system.
The company is now able to combine these geological and analytical results with the historic data to continue to understand the process of the mineralisation and possible areas still untested, helping to plan for a next stage of work.
The reopening of the old underground mine is ongoing and the company is looking forward to updating the market on this work and all other work as information becomes available.
