Preliminary metallurgical tests indicate a gold recovery of 95.7% using a standard gravity and flotation circuit, followed by cyanidation. Mineral Resource Statement (From SRK Consulting, November 13, 2014).


Within the lenses, there are a number of sub-horizontal to shallow easterly plunging, higher grade, and more continuous shoots extending for over 700 meters along strike.

The gold-bearing pyrite stockwork mainly consists of pyrite stringers with minor tourmaline needles; the stringers are typically less than 1 centimeter in thickness and are oriented in several directions (Figure 3).

The Windfall Lake property occurs within the Urban-Barry Greenstone Belt located in the eastern part of the Abitibi Subprovince.

The Urban-Barry Greenstone Belt has an east-west extent of 135 kilometres and is 4 to 20 kilometres wide.

The stockwork mineralization is hosted within volcanic rocks and various generations of porphyry dikes except for the Red Dog dikes, which postdate the emplacement of the pyrite stockwork.

Some of the fragments in porphyry dikes were altered and mineralized prior to being brecciated and porphyry dikes locally crosscut the pyrite stockwork mineralization, suggesting that emplacement of the gold mineralization was broadly coeval with the intrusion of the porphyry dikes.

The tholeiitic volcanic rocks are intruded by a series of NE- to E-trending calc-alkalic porphyry dikes that are intimately associated in space and in time with the important gold mineralization.

Alteration is principally silica-sericite-tourmaline with a peripheral chlorite-carbonate halo.

Trace amounts of chalcopyrite, sphalerite, pyrrhotite, arsenopyrite, tetrahedrite, and bismuth sulfosalts are also present around pyrite grains but also as inclusions in pyrite of the pyrite stockwork.
