The Lake Gamble Block lies to the east of the Cinderella Block. In 1984, Yorbeau drilled seven shallow holes on the Lake Gamble Block. These returned several discreet values and were interpreted as the tops of zones 3 and 4 (ZFO1 and ZFO2). No further work was done until March 2006, when Yorbeau drilled Hole 409 to test the Cadillac-Larder Lake Break at a vertical depth of between 600 to 700 meters below surface. Hole 409 is located 2,255.5 metres east of Hole 404.
The hole intersected an entirely new, well-defined quartz stockwork zone in carbonate rocks showing several specks of visible gold.

The 2008 surface core drilling program began in June and commenced on the Lake Gamble target where six holes were planned. This target was selected as the primary target due to the coincidence of a 1,500-meter-long magnetic low with chargeability and resistivity highs. The results from the first holes were so encouraging that additional holes were drilled, which identified a significant gold-bearing zone. As of December 4th, 2008, 20 holes had been drilled totalling 7,714 m.

1: true width is an approximation based on the dip of the Piché Group but could be somewhat different because of structural complexity (folding and shearing) in the CLLB.
An encouraging aspect of the Lake Gamble target is that thick zones of silicification, the strongest type of alteration associated with the gold mineralization, occur in the Piché Group. The relative sequence of alteration from the least altered komatiite rocks is: 1) talc-chlorite (±calcite) schist followed by, 2) “green carbonate” rocks (carbonatized komatiites with fuchsite, a chrome mica) which is the lower level of alteration related to gold deposition (generally low gold grades < 3g/t), which is superimposed by the most intense alteration that is, 3) silicification and quartz veining, frequently accompanied by brecciation. Higher levels of gold at Lake Gamble occur in these silicified zones with minor arsenopyrite, carbonates of calcium, iron and magnesium, and brown tourmaline.
The 2009 surface core drilling program began in June and commenced on the Lake Gamble target. Seven holes totalling 3,635 m were drilled to explore the Lake Gamble mineralized zone, which resulted in extension of the gold zone to the east and the first intercept of high grade gold in the footwall zone in this area.
