LAVAL, CANADA--(Marketwire - Sept. 6, 2012) - TYPHOON EXPLORATION INC. (TSX VENTURE:TYP) is pleased to announce an updated mineral resource estimate for the Fayolle Deposit and results of the metallurgical testwork on the Fayolle Property, which is located near the town of Rouyn-Noranda in the Abitibi Region of Quebec.

The present updated mineral resources are estimated at 1,814,800 tonnes at 2.7 grams of gold per tonne, for 156,000 ounces of gold at a cut-off grade of 0.8 grams of gold per tonne. All of the updated mineral resources are in the indicated mineral resource category, the total inferred resources transferred into this category.

Different capping grades have been applied, and are referenced on the resource table on the following page.

With an average gold recovery rate of 96%, originating from a preliminary metallurgical test, the Company is very satisfied with the results. On the environmental side, testing done on two composites samples suggests that acid generation is highly unlikely to occur from these samples considering the high carbonate/low sulphur content profile of both types of mineralized rocks.

David Mc Donald, President and CEO of Typhoon Exploration Inc. said, "This resource estimate update significantly exceeds our expectations with a 332% increase of the indicated resources. It is noteworthy that all of the estimated resources in this update have been upgraded from the inferred to the indicated category. Furthermore, this new resource estimate seems to show a possible extension at depth, towards the south-east of the Fayolle Deposit Zone. This mineral resource estimate confirms the relevance of continuing the preliminary economic evaluation (PEA), which should be completed by the end of 2012.

The updated mineral resource estimate was prepared by InnovExplo Inc. of Val-d'Or, Quebec, in collaboration with Aurizon's personnel.

Metallurgical testwork was conducted by SGS Mineral Services of Lakefield, Ontario.

(1) All of the mineral resources are in the Indicated mineral resource category.
  • The Independent and Qualified Persons for the Mineral Resource Estimate, as defined by National Instrument 43-101, are Pierre-Luc Richard, M.Sc., P.Geo. and Alain Carrier, M.Sc., P.Geo. from InnovExplo Inc,
  • Results are presented undiluted and in situ. The estimate includes four (4) gold-bearing zones.
  • Resources were compiled at a range from 0.40 g/t Au to 5.00 g/t Au cut-off grades. Cut-off grades must be re-evaluated in light of prevailing market conditions (gold price, exchange rate and mining cost). Note that no pitshell was used.
  • A fixed density of 2.82 g/cm3 was used in ore zones.
  • A minimum true thickness of 2.0 m was applied, using the grade of the adjacent material when assayed, or a value of zero when not assayed.
  • High grade capping was done on the raw data and established at 40g/t Au for Zone 1 and Zone 2 and at 90g/t Au for Zone 3.
  • Compositing was done on drill hole sections falling within the mineralized zone envelopes (composite = 1 metres).
  • Resources were evaluated from drill hole using an ID2 interpolation method in a multi folders percent block model.
  • The Indicated category is defined by the drillholes spacing and established geological continuity.
  • Ounce (troy) = Metric Tons x Grade / 31.10348. Calculation used metric units (metres, tonnes and g/t).
  • Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
  • The number of metric tons was rounded to the nearest hundred; grades are expressed at 1 decimal; ounces were rounded to the nearest 1 thousand. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations in National Instrument 43-101. InnovExplo is not aware of any known environmental, permitting legal, title-related, taxation, soci-political, marketing or other relevant issue that could materially affect the Mineral Resource Estimate.
  • The Fayolle Deposit Mineral Resource technical Report will be filed on Sedar ( within 45 days.

In comparison with the 2007 estimate, the indicated resources of the Fayolle Project have increased of 332% (compared with the 0.5 g/t cut-off grade). The previous resource estimation prepared for Typhoon Exploration Inc., by InnovExplo Inc. dated as of February 21, 2007, included a resource sensitivity table using different cut off grades. At a cut-off grade of 0.5 grams of gold per tonne, indicated mineral resources totalled 464,700 tonnes at 2.4 grams of gold per tonne for 36,081 ounces of gold, and inferred mineral resources totalled 2,191,100 tonnes at 1.6 grams of gold per tonne for 113,021 ounces of gold. (Ref. ¨Mineral Resources Evaluation of the Fayolle Gold Deposit, 43-101 Technical Report¨ prepared for Typhoon Exploration Inc., dated February 21, 2007 available on SEDAR)


Gold mineralization of the Fayolle Zone is mainly contained in deformed komatiitic rocks and altered intermediate intrusions near the contact with massive basalt and silicified sediments. Shear zones and fault patterns observed are generally oriented west to north-west, corresponding to a major inflexion of the La Pause Fault.

The dense and complex dykes swarm is characterized by changing orientation and perceived as a strong favourability indicator for gold mineralization.

Mineralization is part of a stacking of pluri-metric zones located inside a 50 to 100 metre wide favourable structure, plunging moderately towards the east. Visually, this mineralized structure corresponds to tectonic breccias. The grades can generally be correlated with the intensity and complexity of brecciation. Alteration is characterized by carbonates, chlorite and fuchsite in ultramafic rocks and by albite-hematite in dykes. Gold is mostly observed as free grains up to a millimetre in size in both host rocks.

The updated mineral resource estimate integrates the results of all the drill programs on the Fayolle Deposit since the mineral resource estimate prepared by InnovExplo Inc. on February 21, 2007, part of the Typhoon-Aurizon option agreement.


As the gold can be found in two different types of rock, two gold-bearing composite samples were examined by SGS Mineral Services: a Komatiite composite, containing an assay grade of 7.78 grams of gold per tonne and an intrusive composite, containing an assay grade of 4.59 grams of gold per tonne. After 48 hours, gold recoveries ranged from 94% to 97% for both composites. Finer grinding typically increased the gold recovery, at the cost of higher cyanide consumption.

Table #1 Ore cyanidation recovery results
Sample Average Size P80 (micron) Recovery 48 hours without gravity (%) Recovery 48 hours including gravity (%) Calculated Head grade (g/t Au)
Komatiite 106 94 95 7.57
Komatiite 68 94 97 6.96
Intrusive 103 95 94 4.93
Intrusive 68 96 97 4.51

Gravity separation testing on the Komatiite composite showed a 27.3% Gravity Recoverable Gold ("GRG"). Gravity separation testing on the Intrusive composite showed a 41.4% GRG. The combination of gravity recovery and cyanidation of the gravity tail did increase the overall gold recovery by 1-3%. This demonstrates that this concept would be beneficial from a plant design and financial perspective.

Table #2 Gravity recovery
Samples GRG (Gravity Recoverable Gold) (%) Gravity concentrate grade (g/t) Calculated Head grade (g/t Au)
Comp. 1 27.3 4281 6.62
Comp. 2 41.4 3793 4.93

Bond ball mill testing indicated that the two composites fell in the medium range of hardness compared to the SGS database (12.0-14.1 kWh/t).

While this test work is preliminary in nature and has only been performed on two composite samples, we are encouraged by these initial results, which suggest high gold recoveries utilizing conventional processes.


The drill programs completed to date aimed at obtaining information inside the Fayolle Zone down to a depth of about 250 metres, and laterally along 200 metres. The new updated mineral resource estimate indicates the potential to delineate mineralization at a grade above 5 grams of gold per tonne, using a tight drilling pattern and following different orientations.

Efforts have been made during the last two years to test the mineralized system influence outside the Fayolle Zone with 41 holes drilled at a 100 to 150 metre-wide spacing along a 2 kilometre long trend. Mineralized intersections, in the range of 1 to 8 grams per tonne over a thickness comprised between 3 to 10 metres, have identified different parallel gold bearing structures located a few hundred metres south of the Fayolle Zone (See Aurizon's press release dated August 9, 2011).

Future activity on the property will focus on re-evaluating the exploration potential and the drilling approach adapted to the particular geometry of the Fayolle Zone. Emphasis will be put on eventually extending the zone down to 500 metres.
