Probe Mines Announces Initial Resource Estimate for its Borden Lake Gold Project:
- Borden Lake gold zone estimated to contain an Indicated Resource of 11,607,000 tonnes averaging 0.8 g/t gold for 305,000 ounces of gold and an additional Inferred Resource of 169,322,000 tonnes averaging 0.69 g/t gold for 3,755,000 ounces of gold
- Borden Lake zone also contains a resource of 323,000 ounces of silver in the indicated category, and 5,017,000 ounces of silver in the inferred category
- Three "satellite" gold zones identified which were not included in this Initial Resource Estimate
Toronto, August 23, 2011 -- PROBE MINES LIMITED (TSX-V: PRB) ("Probe" or the "Company") is pleased to announce that the Company has received the initial mineral resource estimate for its Borden Lake gold deposit from Micon International Limited ("Micon").
The resource estimate, which meets the guidelines for reporting mineral exploration programs as set out in National Instrument 43-101, was based on an initial 78 diamond drill holes that tested the gold horizon along approximately 1600 metres (m) of strike length and to a vertical depth of approximately 340 m at a spacing of between 50 m to 100 m. Mineralization at Borden Lake is comprised of a volcano-/meta-sedimentary horizon containing a thick, continuous and consistent zone of gold-bearing disseminated sulphide mineralization. As well, three additional gold zones were identified from the assay data, and will require further delineation before potentially being added to the resource. The deposit remains open in all directions.
The following two tables summarize the Borden Lake gold mineral resource estimate in the indicated and inferred resource categories, respectively, at various cut-off grades. The figures are cumulative for each successive cut-off grade. For the purpose of this press release, the Company is reporting the figures at the 0.3 g/t cut-off grade:
INDICATED MINERAL RESOURCE ESTIMATE
INFERRED MINERAL RESOURCE ESTIMATE
1. Tonnes and ounces have been rounded to the nearest thousand
2. Figures/numbers for resource tonnes and ounces may not tally due to rounding
Mineral resources do not have demonstrated economic viability. The estimate of mineral resources may also be materially affected by other relevant factors or issues. There is no guarantee that the project will be placed into production. Micon is currently in the process of completing the NI 43-101 Technical Report supporting the estimate and the Technical Report will be filed within 45 days of this press release with SEDAR.
The mineral resource estimate was calculated using both Ordinary Kriging and Inverse Distance Cubed methods, which gave similar results. The reported figures are taken from the Inverse Distance Cubed modeling, which provides better definition of the higher grade portions. The mineralized material was classified into the Indicated or Inferred mineral resource category on the basis of a combination of the following factors: (a) confidence in the geological and mineralization continuity, (b) position of blocks in relation to the range of influence as defined by the variographic analysis and (c) and the search ellipse ranges The Borden Lake gold deposit Indicated resource has been categorized taking into account the search parameters in relation to variographic results, and the observed geological and mineralization continuity based on sectional interpretation.
The reported cut-off grade of 0.3 g/t Au is based on consideration of other gold deposits that show similarity in volume and grade to Borden Lake.
The on-going drill program at Borden Lake is now on Hole BL11-108 and it is expected that the pending assay results from these holes will facilitate the upgrading of much of the resource from the inferred category. In addition to infill drilling within the area of the resource estimate, drilling is also focused on expanding the limits of the mineralization and further defining the satellite gold zones identified in the current report. The Company anticipates the commissioning of an updated resource estimate as the drilling progresses. Preliminary metallurgical investigations are already in progress and all future resource updates will be constrained within a pit shell.
David Palmer, President of Probe states "We are extremely pleased with the results of the initial resource estimate. To delineate such a significant volume of mineralization in less than nine months is a testament to the untapped potential of the Borden Lake Project. The lack of previous exploration in this area has provided us with an incredible opportunity and the Company will be focussed on adding to the successes we have seen thus far."
