Re: News Releases - Monday, November 28, 2011 Title: Probe Mines Announces Positive Preliminary Metallurgical Results for its Borden Lake Gold Project
Toronto, November 28, 2011 -- PROBE MINES LIMITED (TSX-V: PRB) ("Probe" or the "Company") is pleased to announce that it has received positive preliminary gold metallurgical results from its Initial Scoping Metallurgical Study for the Borden Lake Gold Project near Chapleau, Ontario. The testwork was carried out on two composite samples, one higher-grade and one lower-grade, Composite 1 and Composite 2, respectively, taken from drill core samples through the discovery section of the Borden Lake Deposit. Metallurgical test results for gold ("Au") indicate recoveries of up to 90.4% Au for Composite 1 and 92.6% Au for Composite 2 using standard gravity, flotation and leach methods.
Core samples from BL11-MET were sent to SGS Laboratories in Vancouver where they were combined into the two composite samples, 1 and 2, with average grades of approximately 1.6 g/t Au and 4.2 g/t Au, respectively. As part of the Initial Scoping Metallurgical study, the metallurgical test program results reported here for gold in the two composites consists of: 1) gravity separation of whole ore; 2) flotation testing of whole ore and gravity tailings; and 3) cyanide leaching of whole ore, gravity tailings, flotation tailings and flotation concentrate.
Flotation with and without gravity pre-concentration showed minor differences in gold recovery, indicating that any free gold present in the ore is relatively fine and recoverable by flotation. A combination of flotation and leaching produced the highest Au recoveries in the test work.
Cyanide leaching of whole ore at grind sizes ranging from K80 100 to 144 microns returned gold extractions ranging from 86.4 to 87.7% for the low grade composite and 90.1 to 91.8% for the high grade composite. Finer grinds have yet to be evaluated.
Full results are not yet in hand, but available data from cyanidation tests on gravity tailings suggest that gravity recoverable gold is relatively fine and recoverable by conventional cyanidation.
The metallurgical testwork is ongoing and results for silver recoveries, environmental testing of tailings and mineralogical studies are expected shortly.
For each composite, a total of 2 gravity separation tests, 5 whole ore rougher kinetics flotation tests, 4 whole ore open circuit cleaner flotation tests, 4 gravity tails flotation (2 rougher, 1 cleaner, 1 leaching feed) and 6 leaching tests (3 whole ore, 1 gravity tails, 1 flotation tails, 1 flotation concentrate) have been conducted to date. Highlights from these tests are presented in the following tables:

David Palmer, President and CEO, stated "We are very encouraged with the preliminary results from this initial metallurgical program, which has demonstrated that we can obtain good recoveries with standard, cost-effective methods. As with the drilling and resource estimates, these preliminary metallurgical results continue to validate the Borden Lake project's economic potential. We are now focusing on the next phase of test work in order to optimize recoveries and the process flow sheet."
