The Cluff Lake Exploration Project adjoins the former Cluff Lake Mine. The Cluff Lake Mine was operated by Orano (formerly Areva), the French multinational nuclear fuel company, from 1980 to 2002 producing 64.2mlbs of U3O8 @ 0.92% U3O8. The Cluff Lake Exploration Project comprises three claims totalling 4,833 hectares and borders the Cluff Lake Mine property on two sides.

The Cluff Lake Exploration Asset is also located 10km north of Orano-UEX’s Shea Creek deposit (Resources of 96mlbs @ 1.3% U3O8), 75km north of NextGen’s Arrow Deposit (Resources of 337.4mlbs @ 1.8% U3O8) and 75km from Fission Uranium Corp’s Triple R Deposit (Resources of 135.1mlbs @ 1.8% U3O8).

Boulder-trains with grades of up to 16.9% U
3O8 have been discovered in the northern portion of the Cluff Lake Exploration Project. In the southern area there are 6 sandstone boulders together that assayed between 0.32% and 3.7% U3O8 with adjacent basement boulder assaying 8.95% and 1.72% U3O8

The Cluff Lake Exploration Project has had very limited historical exploration despite its close proximity to a number of world class uranium projects. Limited historical drilling has intersected anomalous radioactivity and strong pale green alteration associated with the Cluff Lake breccia, at the Donna Zone this alteration and brecciation is 40 metres thick and sits on a 3km long VTEM anomaly and is coincident with a boulder train with samples up to 16.9% U3O8. Further historical drilling to the south encountered 10 metre wide pyritic-graphitic shear to breccia zones which are an ideal reductant for the precipitation of uranium.  These host rocks and alteration zones are similar to those that hosted significant uranium mineralisation at Orano’s former Cluff Lake Mine.

A number of walk-up drill targets have been identified at the Cluff Lake Exploration Project. The Donna zone has only received 12 holes all drilled between 2014-15 and requires further work due to zones of anomalous radioactivity coincident with a large gravity low, with high grade boulders and conductors, there is ample room for discovery at the Donna Zone.

Conductor 1B is north of Skull Lake, initially drilled in 2014 with a single hole and 3 further holes in 2015. The initial holes intersected wide intervals of graphitic ultra-myolonite along the contact with Earl River Complex granitic gneiss, a similar setting to the past producing Dominique—Peter zone at Cluff Lake. Conductor 1B is the initial stand out target. Further targets are being assessed based on revisiting all of the older datasets.
