Rockridge Resources Secures Option to Acquire 100% of the Knife Lake Copper Vms Project in Saskatchewan and Announces Financing

November 1, 2018

Vancouver, BC –Rockridge Resources Ltd. (TSX-V: ROCK) (“Rockridge”) (the “Company”) has entered into an Option Agreement (the “Agreement”) with Eagle Plains Resources Ltd. (TSX-V: EPL) to acquire a 100% interest in a property that covers the majority of the historic Knife Lake Cu-Co-Zn-Ag VMS deposit. The contiguous claims total approximately 85,196 hectares and are located approximately 50 km northwest of Sandy Bay, Saskatchewan (the “Knife Lake Project” or “Property”).

Knife Lake Region


  • The Knife Lake Project area is an advanced-stage copper, silver, zinc and cobalt exploration property in Saskatchewan that has had extensive exploration from the late 1960’s to the 1990’s with the last documented work program completed in 2001.
  • Late in 1998, Leader Mining published a historical estimate of the shallow Knife Lake deposit, reporting a drill-indicated, historical resource of 20.3 million tonnes grading 0.6% Cu, 0.1 g/t Au, 3.0 g/t Ag, 0.06% Co and 0.11% Zn.
  • Higher grade zone of 11.0 million tonnes grading 0.95% Cu within this historical estimate.
  • Historical drill results include 1.37% Cu, 5.07 g/t Ag, 115 ppm Co, 1182 ppm Zn over 60.13 m beginning at a depth of 2.37 m  in hole K-96-02 as well as 0.99% Cu, 4.73 g/t Ag, 103 ppm Co over 38.83 m beginning at a depth of 6.11 m  in hole K-96-36.
  • There is strong discovery potential in and around the deposit as well as at regional targets on the Property.
  • The Company is planning for an initial diamond drill program in early 2019 with drill permits having been received; details of the drill program are forthcoming.

Rockridge’s President and CEO, Jordan Trimble commented: “This is a significant milestone for Rockridge as we look to position the Company as a go-to copper and battery metal exploration and development company. The Knife Lake Project is located in a top mining jurisdiction, has seen extensive exploration and drilling, and boasts a near-surface historical resource which is open along strike and at depth. There is robust discovery potential in and around the deposit as well as on regional targets on the property. Worth noting is that most of the historic exploration was carried out in the 90’s and ceased due to low metal prices. Rockridge is planning for a winter drill program to commence early in 2019 as we look to unlock value at the project with a new look at the exploration and drilling going forward.”

Knife Lake Geology and History

The Knife Lake Project is interpreted to be a remobilized VMS deposit. The stratabound mineralized zone is approximately 15 m thick and contains copper, silver, zinc and cobalt mineralization which dips 30° to 45° eastward over a strike-length of 4,500 m, with an average horizontal width of approximately 300 m. Over 400 diamond drill-holes have been completed in and around the current property boundaries, with much of the drill core stored under cover and in very good condition.

Knife Lake Deposit Map:

Knife Lake Location and Highlights

The deposit is hosted by felsic to intermediate volcanic and volcaniclastic rocks which have been metamorphosed to upper amphibolite facies. The deposit is typical of VMS mineralogy which has been significantly modified and partially remobilized during the emplacement of granitic rocks. The mineralization straddles the boundary between two rock units and occurs on both limbs of an overturned  fold.

The Knife Lake area saw extensive exploration from the late 1960’s to the 1990’s with the last documented work program completed in 2001. Drilling has outlined a series of stratabound mineralized lenses which are controlled by complex geological structures. In the copper mineralized zone, significant thickening of the mineralization occurs near the central portion of the deposit. Sulphides and rare native copper are visible in outcrop. Massive sulphides consist of 25% to 60% pyrrhotite and 0.2% to 10% chalcopyrite mineralization. Pyrite is present as irregular disseminations and masses. Locally, up to 8% sphalerite (zinc mineralization) is present.

The first documented work in the Knife Lake showing area occurred between 1969-1973, consisting of ground and airborne geophysical surveys and extensive soil geochemical sampling. The discovery drill-hole, collared in September, 1969, returned 2.37% Cu over 4.48 m from 19.96-24.44 m, including 3.5% Cu over 2.5 m from 20.27-22.77 m. A total of 96 diamond drill holes (8,232 m) were completed between 1969-1971 and in 1973 Straus Exploration announced a maiden resource on the Knife Lake Deposit. 

Hudson Bay Exploration and Development Company Ltd. later carried out a regional Airborne EM geophysical survey in the Knife Lake – Scimitar Lake area, followed up by geological mapping, prospecting, ground geophysics and diamond drilling. The property was subsequently optioned to Copperquest Incorporated in 1989, who carried out further geophysical and geochemical surveys and optioned the property to Leader Mining International in 1996. Between 1996 and 2001, Leader flew various airborne geophysical surveys in the area, including electromagnetic (“EM”), magnetic, and gravity surveys. This was followed up with stripping and trenching of the outcropping deposit area. Ground TEM, magnetic, ground IP/Resistivity and VLF-EM surveys were completed over and adjacent to the main deposit area. 

Between 1996 and 1998, Leader completed 315 diamond drill holes, outlining a broad zone of mineralization occurring at less than 100 meters depth (AF 63M-0006, Report 10). Late in 1998, Leader published a historical estimate for the deposit, reporting a drill-indicated resource of 20.3 million tonnes grading 0.6% Cu, 0.1 g/t Au, 3.0 g/t Ag, 0.06% Co and 0.11% Zn. Within the historical estimate there is a higher grade zone containing 11.0 million tonnes grading 0.95% Cu. (SMDI 0406). Rockridge Resources’ management considers these estimates to be historical in nature and cautions that a Qualified Person has not done sufficient work to classify the historical estimates as current mineral resources or mineral reserves in accordance with National Instrument 43-101.  These estimates do not comply with current definitions prescribed by National Instrument 43-101 or the Canadian Institute of Mining, and are disclosed only as indications of the presence of mineralization and are considered a target estimate to help guide additional work.  The historical models and data sets used to prepare these historical estimates are not available to Rockridge, nor are any more recent resource estimates or drill information on the Property.  

In 1997, Leader International shipped a 2.4 tonne bulk sample of mineralized material excavated from the surface outcrop of the Knife Lake deposit to Lakefield Research Limited for metallurgical test-work. Lakefield concluded that the copper metallurgy was straightforward. Following a simple flowsheet, greater than 90% copper recovery was achieved at a concentrate grade of 28% Cu. Gold recovery in the copper concentrate was 80%. The cobalt recovery in the copper cleaner concentrate was 13%, with 28% of the cobalt present in cleaner tailing products. Another 48% of the cobalt was present in the sulphide concentrate.

A 357kV powerline has recently been completed to within 16 km of the Knife Lake Deposit area, greatly enhancing the project’s infrastructure.
