Eagle Plains' Partner Rockridge Reports Final Results from 2019 Knife Lake Drilling Including 2.01% Cu and 2.45% CuEq over 15.2m Starting at 5.1m Downhole

CRANBROOK, BC / ACCESSWIRE / June 10, 2019 / Eagle Plains Resources Ltd. (TSX-V: EPL) ("Eagle Plains" or the "Company") has received notice from Rockridge Resources (TSX-V: ROCK) (Frankfurt: RR0) that it has received and interpreted final results from the 12 hole, 1053 m inaugural winter drill program completed on Eagle Plains' 100%-owned Knife Lake Project (the "Property"). Rockridge has an option to earn a 100% interest in the 85,196 ha Property by making $150,000 in cash payments, completing $3,250,000 in expenditures and issuing 5,250,000 shares to Eagle Plains. The Property is located 50km northwest of Sandy Bay, Saskatchewan and covers the majority of the historical Knife Lake Cu-Zn-Ag-Co VMS deposit.

The analytical results are summarized below and indicate high grade intercepts in six holes, including a wide intercept in hole KF19006. Drill hole KF19006 tested the up-dip extension of the Knife Lake deposit in an area that had not been previously tested. The drill hole intersected net-textured to semi-massive sulphide mineralization from 5.1m to 20.3m downhole. The 15.2m interval returned 2.01% Cu, 0.39 g/t Au, 8.16 g/t Ag, 0.17% Zn, and 0.02% Co for an estimated 2.45% CuEq**. Drill hole KF19007, which tested the down-dip extension of the deposit in the same area as KF19006, intersected interstitially-forming to net-textured sulphides between 39.1m to 42.0m. KF19007 returned 2.95m of 0.66% Cu, 0.1 g/t Au, and 2.6 g/t Ag for an estimated 0.82% CuEq**.

Drill holes KF19009, KF19010, KF19011, and KF19012 were drilled in the southern extent of the deposit in areas that had either not been drill tested and/or where historical assays had not been validated. All four drill holes intersected zones of disseminated, interstitially-forming to net-textured sulphide mineralization. Drill hole KF19011 intersected 14.2m of 0.60% Cu, 0.07 g/t Au, 2.02 g/t Ag, 0.20% Zn, and 0.01% Co for an estimated 0.77% CuEq**. Drill hole KF19012 intersected 10.6m of 0.61% Cu, 0.09 g/t Au, 2.6 g/t Ag, and 0.17% Zn for an estimated 0.76% CuEq**. Interpretation and QA/QC has now been completed on all twelve holes from the program. Highlighted intersections from the drill holes are reported in the table below.

Rockridge is now working towards completing an NI 43-101 compliant resource estimate for Knife Lake which will include results from the 2019 drill program. Rockridge also intends to complete a summer exploration program on the Knife Lake project.

Summary of Knife Lake Holes 1 - 5 (see details as reported April 30th, 2019 and May 06, 2019)

* Drill indicated intercepts (core length) are reported as drilled widths and true thickness is undetermined

** Assumptions used in USD for the copper equivalent calculation were metal prices of $2.80/lb Cu, $18.00/lb Co, $1,300/oz Au, $17.00/oz Ag, $1.20/lb Zn and a processing cost of $11.55/tonne. Copper equivalent (CuEq) was calculated using the formula CuEq = Cu% + ((Zn%*Zn Price*Zn Recovery*Zn Payable*22.0462) + (Co%*Co Price *Co Recovery*Co Payable*22.0462) + (Augpt*Au Price*Au Recovery*Au Payable/31.1035) + (Ag *Ag Price*Ag Recovery*Ag Payable/31.1035)) / (Cu price*CuRecov*Cupayable*22.0462)

Rockridge completed twelve holes consisting of 1,053m of diamond drilling in the 2019 winter drill program. This represents the first work on the property since 2001 and has two primary objectives: confirm the tenor of mineralization reported by previous operators and expand known zones of mineralization. All activities will advance the project toward the goal of completing a NI 43-101 compliant mineral resource estimate.

Compilation and initial modelling indicates potential for expansion of the historical deposit at depth. The current drilling has been focused on resource upgrade and expansion as well as infill drilling between historical holes. The program will also give the Company's technical team valuable insights into the property geology, alteration, and mineralization that will be applied to future regional exploration on the highly prospective and underexplored land package.

Knife Lake contains typical VMS mineralogy which has been significantly modified and partially remobilized during the emplacement of granitic rocks. Therefore, the known historical deposit may represent a remobilized portion of a presumably larger "primary" VMS deposit based on general observations about the mineralogy, mineral textures and metal ratios in the deposit. Most of the historical work consisted of shallow drilling at the deposit area with little regional work carried out and limited deeper drilling below the deposit. As a result, there is strong discovery potential both at depth and regionally.

Knife Lake Geology and History

The Knife Lake area saw extensive exploration from the late 1960s to the 1990s with the last documented work program completed in 2001. The most recent work was carried out by Leader Mining International Ltd. 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 0.75% Cu in addition to other metals (SMDI 0406). All disclosed historical estimates were completed prior to the passing of NI 43-101 into law and as such the Company advises that these mineral resource estimates, as disclosed, are not supported by a compliant National Instrument 43-101 technical report, contrary to NI 43-101. A qualified person has not done sufficient work to classify these historical estimates as current mineral resources or mineral reserves in accordance with NI 43-101. The above resource estimates are from the Saskatchewan Mineral Deposit Index (SMDI) 0406. The Company is not treating the historical estimates as current mineral resources or mineral reserves. These estimates do not comply to categories 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 to be a guide for additional work. The historical models and data sets used to prepare these historical estimates are not available to Eagle Plains and the Company is not aware of any more recent resource estimates or data. The 1998 historical resource was calculated using the cross-section method and used assay data from 241 Leader holes and from 6 other holes drilled prior to Leader's drilling. A cutoff grade of 0.3% copper-equivalent and a minimum composite length of 3.0 meters was used. Holes were plotted on vertical drill sections ranging from Section 20760 N to Section 24905 N, covering a strike length of 4,145 meters. The categories used for the Leader Mining 1998 historical resource estimates are stated as being "drill-indicated". This is not a resource category as defined under 43-101 CP Section 2.4 (1) and (2)6 but based on the methodologies and drill hole spacing it would likely be equivalent to an inferred resource category.

Drilling at Knife Lake 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. 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 stratabound mineralized zone is approximately 15m thick with irregular contacts and contains copper, silver, zinc and cobalt mineralization which dips 30 ? to 45 ? eastward over a strike-length of 4,500m, with an average horizontal width of approximately 300m. 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.

A 357kV powerline runs within 16 km of the Knife Lake Deposit area, greatly enhancing the project's infrastructure.

QA/QC

Samples were sent for geochemical analysis with ALS Global, Vancouver for the following analyses: 48 element four acid ICP-MS (ME-MS61) and gold (Au) 30 g Fire Assay - AA finish (Au-AA23). Over limit analysis were completed using the following analyses: Ore Grade copper (Cu), nickel (Ni) and zinc (Zn) - four acid ICP-AES (ME-OG62).

On receipt of final certificates of analysis, the QA/QC sample results were reviewed to ensure the order of samples were reported correctly, that the blanks ran clean, and that the results for each standard had minimal variance from its certified value. QA/QC for the Knife Lake drilling included certified reference material ("CRM's") and blanks that were inserted into each sample batch in order to verify the analytical from the lab. The CRM's from the first five drill holes reported passed within 2 standard deviations and the blanks returned acceptable values. All of the lab internal standards and duplicates were within acceptable values.

Complete analytical results are available on the Rockridge Resources website.
