Rocky Lake Property

The 100% owned Rocky Lake property consists of 3,446 hectares in the affluent VMS region of Flin Flon and Snow Lake, Manitoba and hosts the Rocky Lake VMS deposit. 

Copper-zinc production from volcanogenic massive sulphide (VMS) deposits in Manitoba dates back to the first discovery at Flin Flon in 1914. Since then, the Paleoproterozoic Flin Flon domain has been firmly established as one of the most prolific VMS districts worldwide. Despite nearly a century of systematic exploration, new VMS deposits continue to be found, including the world-class Lalor deposit of Hudbay Minerals Inc., which saw initial production in August 2012. The total resource at Lalor stands at over 19 million tonnes grading 0.85% Cu, 3.15% Zn, 4.22 g/t Au and 27.55 g/t Ag, further demonstrating the exceptional potential of the district.

Project Highlights

  • Located in the major VMS production zone which includes the Lalor Lake mine and 10 others are located
  • Hosts the Rocky Lake VMS Deposit
  • Infrastructure in place (highways, rail and power), mining smelter to the southeast
  • Massive sulphide mineralization with visible chalcopyrite confirmed on the main Rocky Lake target
  • 2012 drill hole intersected top zone of a significant intersection of massive sulphide consisting of 0.3 metres (1ft) of 15.8ppb gold, 2,584ppm copper, 300ppm zinc and 15% iron
  • Another drill hole intersected 10m (33 ft) of 9.61ppb gold, 4,617ppm copper, 198ppm zinc and 26% iron
  • Previous work performed in the area by Hudson Bay Minerals (HBM) and Inco; airborne surveys, ground geophysics, and drilling lead to discovery of Namew Lake nickel and copper deposit
  • HBM drilled 10 holes totaling 2,292 meters over a 5 km EM conductor with all holes intersecting copper mineralization
  • Crone Geophysics completed a 23 km Pulse Time Domain Electromagnetic (PEM) survey for QMC that delineated a strong 600 m long conductor anomaly previously unidentified by HBM, suggesting that the conductor was missed by the HBM drilling

Visible Chalcopyrite

QMC Exploration

The Company has completed a helicopter airborne VTEM survey on the property. In December 2011, QMC commenced a 1,025 metre drilling program on the property which was completed in the spring of 2012 and results confirmed massive sulphide mineralization with visible chalcopyrite mineralization in the core.

Detailed re-interpretation of VTEM data by Maxwell Modelling on the main Rocky Lake massive sulphide target showed the presence of a deep-seated conductor. This conductor appears to be at least 1,000 metres long and seated at a depth of minimum 200 metres. The top of the conductor was confirmed by drill holes RL11-2 and RL12-5. Massive sulphide mineralization was intersected at the bottom of RL11-2 at a vertical depth of 193 metres. Mineralization consists of semi-massive sulphides, mostly pyrrhotite and pyrite with visible chalcopyrite, and is hosted near the contact of the hanging wall felsic rocks with the footwall mafic rocks. The drill hole was stopped in mineralization because of drilling problems.  Assays from the mineralized core at the bottom of the drill hole returned 30 cm grading 0.26% copper within a semi-massive sulphide section of approximate 20% total iron sulphides.

Drill Hole RL12-5 also intersected semi-massive sulphides at a vertical depth of 171 metres.  The intersection returned highly significant values of copper within a zone averaging 18% to 20% iron sulphides over 9 metres.

These results indicate that a more extensive drilling program to fully test the mineralized VMS system is warranted.  Seven (7) drill holes at a spacing of 100 metres are recommended to test this conductor along strike and depth.  The other holes drilled in this zone (RL11-1 and RL11-3) were much shallower and did not intersect the deep conductor; however, they returned significant values in copper.  RL11-1 also returned anomalous copper with values up to 400 ppm from 147 metres to the end of the hole at 222.50 metres. 

The two semi-massive sulphide intersections (drill holes RL11-2 and RL11-5) also confirms the geological re-interpretation of the Hudson Bay’s historical diamond drilling program and that Hudson Bay missed the deep-seated massive sulphide mineralization.
