ASX Announcement & Media Release
9 October 2007
METALLURGICAL UPGRADE POTENTIAL CONFIRMED
Highlights
• Metallurgical testing results of Canegrass Nickel Cobalt Project
• Confirms expected upgrade potential and nickel recovery from wet screening
• Similar beneficiation characteristics to Norilsk Nickel’s Cawse deposit
Halcyon Group Ltd (ASX:HCY) is pleased to announce results of metallurgical testing of its Canegrass Nickel Cobalt Project,
(tenements M24/290 and M24/39) covering an area of 15.4 km2 of the highly prospective Walter Williams Formation, located 70
kilometres north west of Kalgoorlie.
Metallurgical bulk samples of “upgradeable ore” were extracted using a Caldwell rig in the Patch-Gulch area in June 2007. The
samples were tested for beneficiation potential (wet & dry screening), grindability, abrasion index, and sizings by AMTEC.
Comparing dry and wet screening, samples from Patch-Gulch area provide expected upgrades to Ni % and Ni metal recovery. The
results confirm that wet screening is more effective than dry screening, with the grade doubling and a 50% recovery of Ni metal.
For example, a head grade sample as low as 0.45% Ni was beneficiating up to 0.9% Ni with a 50% recovery.
Managing Director, Iggy Tan said that the positive results confirm exactly what the Company expects of the Canegrass ore body.
The project is roughly 25 km along strike to the Cawse Nickel Operations owned by Norilsk Nickel.
“As we expected the beneficiation potential of our ore is very similar to the Cawse deposit. The Cawse operation utilises a
crushing and wet screening beneficiation plant at the front end of their process and obtain very similar upgrade performances”, said
Mr Tan.
