Overview of Hammer's Millennium cobalt project in Queensland

High grade cobalt-copper assays for Hammer

ASX listed Hammer Metals has announced some very encouraging cobalt-copper drilling results from its Millennium JV project, about 30km west-northwest of Cloncurry within the Mt Isa mining district in western Queensland.

The diamond drill program successfully tested the up-dip continuity of cobalt-copper mineralisation at the northern end of the Millennium deposit and the results were very encouraging.

The best intercept was 7 metres grading 0.15% cobalt, 0.36% copper and 0.12g/t gold from 14m down-hole, including 2m @ 0.33% cobalt, 0.57% copper and 0.11g/t gold from 19m down-hole.

Further high-grade assays included 2m @ 0.64% cobalt, 0.29% copper and 0.14g/t gold from 62m and 4m @ 0.23% cobalt and 0.18% copper from 69m down-hole within the same drill hole.

Overall, the highest single metre intersection topped out at 0.71% cobalt, 1.1% copper, 1.1g/t gold and 62g/t silver outlining the high-grade nature of the cobalt at Millennium and the solid copper, gold and silver supporting grades.

Results are pending from the final 4 holes completed during the recent program and will be announced to the market soon.

According to Hammer, all mineralisation intersected during the program contains unoxidised, primary sulphides, with a thin zone of oxidation at surface of about 10-15 metres thick.

Metallurgical studies, including sighter flotation test work of the high-grade sulphide mineralisation will begin in the near future and the company also said it will commence updating the mineral resource estimate for the Millennium JV project shortly.

The project currently holds inferred mineral resources totalling 5.9 million tonnes grading 0.32% copper, 0.11% cobalt and 0.11g/t gold. 

The deposit is less than 20km from CuDeco’s Rocklands copper project, which held a pre-mining resource of 96 million tonnes grading 0.45% copper, 0.13g/t gold and 0.03% cobalt in multiple lodes within an iron oxide copper gold ore deposit.

The company also announced the identification of a new exploration target known as the Northern Extension, approximately 1km north of the existing resource at Millennium.

Rock chip sampling at the new target returned exceptional assays up to 45.3% copper and a number of other encouraging results of up to 0.12% cobalt, 0.21g/t gold, 42.6g/t silver, 0.16% lead and 0.25% zinc.

The reconnaissance sampling program followed up highly anomalous copper and arsenic soil geochemical results and historical rock chip sampling showing elevated cobalt and copper values in the area.

The Northern Extension has similar geological rock sequences to the main Millennium mineralisation and hence is a high priority area for Hammer.

The company is finalising drill targeting at this new prospect for further exploratory testing in the future.

The Millennium cobalt project is a JV with TSX-listed Global Energy Metals Corp, where the latter company has the right to earn 75% by spending a minimum of CAD$2.7m, including CAD$250,000 in cash payments to Hammer.

Hammer will manage the project for the first two stages until GEMC earns a 65% interest, after which management will vest to GEMC.
