Russell Lake Project Location Map

Russell Lake Property Highlights:

  • Option to acquire an initial 51% and up to 100% of Rio Tinto’s 73,294 ha Russell Lake Uranium Property strategically located in the central core of the Eastern Athabasca Basin of northern Saskatchewan
  • Both Highway 914 servicing McArthur River and a high-voltage power line connected to the provincial power grid run through the Property’s western claims. There is a fully permitted exploration camp on the Project suitable for over forty people located on the highway and within 5 kilometres of Denison’s Phoenix deposit
  • Skyharbour, as operator, can earn an initial 51% interest in the Property by paying CAD $508,200 in cash, issuing 3,584,014 common shares to RTEC, and funding CAD $5,717,250 in exploration on the Project, inclusive of a 10% management fee to Skyharbour, over a period of 3 years
  • Skyharbour has a second option to earn an additional 19% interest for a total of 70%, and a further possible option to obtain the remaining 30% interest in the Project for an undivided 100% ownership interest
  • The Property has been the subject of significant historical exploration efforts including over 95,000 metres of drilling in over 220 drill holes. This provides the Company with an excellent dataset to direct subsequent exploration on high-priority areas with the potential for near-term discovery of high-grade uranium mineralization
  • Previous exploration work has identified numerous highly prospective target areas, some of which host high-grade uranium mineralization in historical drill holes. Furthermore, there are over 35 kilometres of untested conductors on the Property in magnetic lows, which are indicative of pelitic basement rocks conducive to uranium deposition in the Athabasca Basin
  • The Property has a permitted and functional exploration camp suitable for over forty people, and conveniently located near Highway 914 and within 5 km kilometres of Denison’s Phoenix deposit. The Property’s claims are in good standing for 2-22 years from banked assessment credits
  • This transaction adds another drill-ready, advanced-stage uranium exploration asset to Skyharbour’s project portfolio and offers significant operational and exploration synergies with the adjacent Moore uranium project


Russell Lake Uranium Project:

The Russell Lake Project is a large, advanced-stage uranium exploration property totalling 73,294 hectares strategically located between Cameco’s Key Lake and McArthur River Projects and adjoining Denison’s Wheeler River Project to the west and Skyharbour’s Moore Uranium Project to the east. Highway 914, which services the McArthur River mine, runs through the western extent of the Property and greatly enhances accessibility. Similarly, a high-voltage powerline situated alongside Highway 914. Skyharbour’s acquisition of Russell Lake creates a large, nearly contiguous block of highly prospective uranium claims totalling 108,999 hectares between the Russell Lake and the Moore uranium projects.

There has been a meaningful amount of historical exploration carried out at Russell Lake, with most of it conducted prior to 2010. The Property has been the subject of over 95,000 metres of drilling in over 230 drill holes. The Property’s claims are in good standing for 2-22 years with assessment credits built-up from previous programs.

Several notable exploration targets exist on the property including the Grayling Zone, the M-Zone Extension target, the Little Man Lake target, the Christie Lake target, and the Fox Lake Trail target. More than 35 kilometres of largely untested prospective conductors in areas of low magnetic intensity exist on the Property as well.

At the Grayling Zone, drilling of the 2,200 metres long, up to 100 metres thick sub-parallel Grayling conductor intersected an 800 metres long discontinuous zone of basement-hosted uranium mineralization with localized perched and unconformity-hosted associated mineralization along a graphitic thrust fault. Drill hole RL-85-07 intersected 3.45% U3O8 over 0.3 metres at a depth of 363.2 metres and 0.1% U3O8 over 0.5m at a depth of 366.4 metres. This target is prospective for additional high-grade uranium discoveries and is open in several directions.

At the M-Zone Extension target, historical drilling at neighbouring Denison’s M-Zone along trend from the Grayling Zone intersected basement hosted uranium of 0.70% U3O over 5.8 metres at a depth of 374.0 metres. Like the Grayling Zone, the mineralization is hosted by a graphitic thrust fault. The northeast extension of the M-Zone-Grayling corridor onto the Property has seen limited drilling, but mineralization was intersected in historical drilling, returning 0.7 metres of 0.123% U­3O8 at 619.1 metres depth in hole MZE-11-03.

The Little Man Lake Zone target is 500 metres long, 10 to 15 metres thick, 25 to 35 metres wide, and is a zone of prospective geology associated with an unconformity depression. The last drilling in this area was in 1989, prior to modern uranium exploration models, with historical uranium grades ranging from 0.03% up to 0.1% U3O8 at around 300 metres depth.

At the Fox Lake Trail target area, uranium mineralization was intersected in a few historical drill holes. Significant intercepts include 0.0743% U3O8 over 1.0 metres at 525.5 metres depth in hole FLT-08-06, and 0.053% U3O8 over 0.3 metres at 516.9 metres depth in hole FLT-11-14. A prospective quartzite ridge runs through the area along with anomalous geochemistry in faulted basement metasediments. Significant sandstone-hosted sulphides are also found in this area.

The Christie Lake target area contains basement-hosted uranium mineralization with historical drill results returning 0.17% U3O8 over 0.4 metres at 436.4 metres depth in hole CL-10-03. A prospective clay altered basement fault system runs throughout this area.

In addition to the aforementioned target areas, there are more than 35 kilometres of untested conductors on the Property underlain by rocks of low magnetic intensity, suggestive of prospective graphitic meta-pelitic basement rocks. The Project has seen limited exploration in the previous twelve years, so minimal modern exploration techniques and methods have been used to expand existing zones of mineralization as well as to make new discoveries.

There is a fully permitted exploration camp on the Project suitable for over forty people located on the highway and within 5 kilometres of Denison’s Phoenix deposit. Skyharbour is planning an initial phase of exploration and drilling at the Project with details forthcoming.

Jordan Trimble, President and CEO of Skyharbour Resources, stated:

“We are very pleased to have reached an agreement with Rio Tinto to acquire up to a 100% interest in Russell Lake. This is a significant transaction for Skyharbour and involves the acquisition of a premier exploration property adjacent to our Moore project. Uranium properties with the pedigree and prospectivity of Russell Lake are few and far between given the very strategic location, notable historical exploration and findings, as well as the numerous property-wide targets with the potential to generate new discoveries.”

“Additionally, we welcome Rio Tinto as a new strategic shareholder and project partner.  We have a shared vision for the exploration of the various prospective target areas that remain to be fully tested on the Property using modern exploration methods and techniques. We look forward to working with Rio Tinto to generate a new meaningful discovery in the years to come.”
