recent pressrelease next pressrelease

(businesspress24) - August 23, 2019: A-Cap Energy Limited (A-Cap, the Company) wishes to announce the results of recent metallurgical work at the Companys flagship Wilconi Nickel - Cobalt Project (Wilconi) in Western Australia. The Company completed metallurgical drilling in four areas along the twenty-six kilometres of strike of the mineralised system (refer A-Caps ASX announcement dated 30 April 2019) and submitted representative samples to a number of laboratories to test different processing routes. The results clearly demonstrate that the Wilconi ore reacts favourably to a variety of different leaching solutions used in the industry.

Highlights of the metallurgical work are:

- Hydrochloric Acid Leach: -99% of the Nickel and 99.7% of the Cobalt was leached
- Sulphuric Acid Leach:-90% of the Nickel and 76% of the Cobalt was leached
- Nitric Acid Leach: --89% of the Nickel and 88% of the Cobalt was leached

This initial metallurgical work is extremely encouraging, as the work clearly shows that the Company has several treatment options that can be further tested and refined.

In addition, A-Cap is currently conducting further metallurgical work in Australia, Canada and China, investigating other metallurgical methods. The early emphasis on metallurgical studies at Wilconi is aimed at producing a metallurgical flowsheet that shows reduced capital costs when compared with traditional high-pressure acid leach processes.

The Chairman of A-Cap, Mr Shen AnGang, stated: The metallurgical recoveries obtained in this round of metallurgical sampling are extremely encouraging. The simple fact that we know that the nickel and cobalt leach out under atmospheric conditions and, using a number of leaching acids, gives us a choice of flowsheets dependent on project economics. Our Company consultants are currently upgrading the JORC resource at Wilconi and our next phase of work will be more bulk metallurgical sampling and infill drilling.
