TORONTO, June 10, 2014 /CNW/ - Probe Mines Limited (TSX-V: PRB) ("Probe" or the "Company") is pleased to provide a progress update for its metallurgical program on the Borden Gold project. The metallurgical program will be included as part of Probe's anticipated Preliminary Economic Assessment ("PEA").
Probe's metallurgical program has been on-going for the last 3 years and has generated sufficient input data to perform a series of process route trade-off studies, in particular to compare the two main process options: 1) gravity + whole ore leach ("WOL"); and 2) gravity + flotation + leach of flotation residues and reground flotation concentrate ("FLOT") (irrespective of the downstream flowsheet, gold gravity recovery is included in each option). The metallurgical work is based on drill core samples taken from representative drill holes in the Borden Gold project.
The results of the trade-off studies indicate that the WOL option may be superior, subject to further analysis and the PEA. The tests also established that the optimum grind objective for the WOL option was 75 μm.
The resulting metallurgical recovery curve (WOL at 75 μm) is presented in Figure 1. This updated grade recovery curve shows an overall improvement over the curve released in April 2013.
Completed work for the anticipated PEA includes metallurgical and comminution testing on the lower-grade zone (open pit) and the higher-grade zone (underground). Metallurgical tests include gold extraction from gravity, flotation and leach from different geo-domain composites, fine regrind, settling, and In-Line Reactor (ILR) test work. The comminution test program includes: Drop-Weight Test (DWT), SAG Mill Comminution Test (SMC), Bond Ball Mill Work Index (BWi), Rod Mill Work Index (RWi), Abrasion Index (Ai), Unconfined Compression Test (UCS) and Low Energy Impact Test.
Metallurgical testwork is continuing in 2014 in order to continue strengthening the bases for the definition of the process design criteria.
Mr. Yves Dessureault, Chief Operating Officer of Probe, states: "These metallurgical results are very encouraging and continue to improve. There is probably some further upside for gold extraction at higher gold grades and this will be the focus of the 2014 metallurgical program".
A new 3-D model of the Borden Gold deposit is now available on the website, http://www.probemines.com/s/Borden_Lake.asp?ReportID=657509&_Type=Borden-Gold, with interactive analytical tools that will enable investors to better visualize drill results.
The metallurgical testing was carried out under the supervision of BBA Inc. and was conducted by SGS Mineral Services (Lakefield) and Process Research Ortech Inc. (Mississauga). The contents of the above have been approved by Mr. Jacques McMullen, P.Eng, Qualified Person of BBA Inc., independent consultants to Probe.

Forward looking information in this news release includes, but is not limited to, the Company's objectives, goals or future plans, statements regarding exploration results, potential mineralization, the estimation of mineral resources, exploration and mine development plans, timing of the commencement of operations and estimates of market conditions. Factors that could cause actual results to differ materially from such forward-looking information include, but are not limited to, failure to identify mineral resources, failure to convert estimated mineral resources to reserves, the inability to complete a feasibility study which recommends a production decision, the preliminary nature of metallurgical test results, delays in obtaining or failures to obtain required governmental, environmental or other project approvals, political risks, inability to fulfill the duty to accommodate First Nations and other indigenous peoples, uncertainties relating to the availability and costs of financing needed in the future, changes in equity markets, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects, capital and operating costs varying significantly from estimates and the other risks involved in the mineral exploration and development industry, and those risks set out in the Company's public documents filed on SEDAR.
