TORONTO, May 17 /CNW/ - Chieftain Metals Inc. ("Chieftain" or the "Company") (TSX: CFB) has initiated a metallurgical testing program to determine if
opportunities exist to improve recoveries from previous 2007
Since the previous work relating to the previous 2007 feasibility took
place, several significant advances have taken place in controlling
pulp and surface chemistry in sequential flotation of poly-metallic
ores and it is Chieftain's plan to investigate and test these.
Detailed quantitative mineralogy has been conducted on a single sample
from the main ore zone which was available from previous drilling.
This sample has exhibited encouraging indications that overall
liberation of the various ore bearing minerals is favorable to
obtaining high levels of selectivity between Gold, Copper, Lead and
Initial tests indicated that important percentages of coarse gold may be
recovered into a concentrate that can be treated for early revenue
receipts. Silver recovery was also considered to be more favorable than
Tests on this section of old core from the initial extraction area
demonstrated that the application of, closer grinding control and
recently developed and successfully applied flotation reagents, may
significantly improve the selectivity of the milling circuit.
Tests on fresh metallurgical samples will be carried out as soon as the
samples are available to verify the preliminary findings and define the
potential improvements in the quality and quantity of the concentrates
that will be produced.
In particular the most significant developments have been in creating a
more selective regime for the separation of copper and lead minerals
which had been the most difficult step in previous work.
The effective separation of gold values into a combination of a gravity
concentrate and copper concentrates is key to maximizing payable
values, and it would appear that there is no fundamental mineralogical
Chieftain intends to test the potential recovery improvements and has
obtained new samples typical of the proposed production from the
Tulsequah Chief mine in order to confirm the potential improvement.
