VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/05/13 -- Jet Gold Corp. (TSX VENTURE: JAU) (the "Company") announced today progress of exploration of its Big Hammer Gold Silver Tellurium property located 13 kilometers southeast of Terrace, BC. Canada.
Jet Gold has completed filing and reporting of allowable work expenditures for the amount of $467,637 (event 5399022), allowing the Big Hammer tenures to be carried through in good standing to December 2022. Also in 2012/13, a permit amendment was received which increases the current drill sites (12) at its Big Hammer property to a total of 47 sites (amendment letter MX-2-235 1650573). This will allow significant drilling to be undertaken without delay. In January, a small-scale gravity testing pilot commenced to determine feasibility of low cost gravity separation of potential concentrate from gangue (waste). The on-going small-scale gravity concentration test has been undertaken to determine the suitability of potential ore grade material from Big Hammer for 4 key aspects;
-- Suitability for free gold separation by a low cost gravity system;-- Crushing/grinding requirements to free sulphides and gold;-- Determination of the ratio of gangue (waste) to concentrate;-- Determine the chemical content of the gangue.
Phase one of the testing is focused on basic system design and protocol prior to running larger samples. With the positive success of the first phase of this trial, further work will include collection and processing of large samples from the 380 and 625 veins.
A summary of the initial results returned from a random composite sample of various quartz vein material from Big Hammer is provided in the following tables. To date, this testing has determined that an inexpensive gravity system can easily concentrate potential ore at a minimum of 2:1 ratio, with a milling target of approximately 80 mesh (.180 mm).
