VANCOUVER, British Columbia – Polaris Materials Corporation (TSX:PLS) (the “Company”, “Polaris” or “we”) is pleased to announce the receipt of a NI 43-101 maiden Mineral Resource estimate for its Black Bear Project (“Black Bear” or the “Project”) located approximately 5km from the company’s Orca Quarry on Vancouver Island in British Columbia. The resource estimate includes Measured and Indicated Resources of 70 million tonnes and Inferred Resources of 330 million tonnes of basalt material suitable to be processed for use in construction aggregates.

HIGHLIGHTS

• Measured and Indicated Mineral Resource of 70 million tonnes of basalt in a preliminary pit shell with favourable topography for crusher and site infrastructure
• Drilling and surface sampling confirmed geological consistency and continuity of the deposit
• Large Inferred Mineral Resource of basalt supports potential for a multi-decade project that could complement the existing Orca Quarry and has the potential to provide for new product lines
• Existing infrastructure at the Orca Sand and Gravel site may reduce investment requirement versus a standalone quarry operation

The Mineral Resource estimate for Black Bear is constrained within three conceptual pit shells, identified as Phase I, Phase II and Phase III. The Phase I pit shell represents the initial area targeted for development work and is situated on the west part of the Black Bear license. Pit shells for Phase II and Phase III are located east of the Phase I pit and were based on similar considerations to the Phase I conceptual pit.

1. Analyses of samples indicate the basalt material is of suitable quality to permit the production of various construction aggregates.
2. The Mineral Resources in this news release were estimated using current Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves.
3. Resources are constrained within three conceptual pit shells based on preliminary estimates of technical and economic parameters which include a 45° pit slope and that all basalt within the pit shell meets reasonable prospects of eventual economic extraction.

“The maiden resource estimate at Black Bear, based on our initial exploratory drilling and surface sampling, contains 70 million tonnes of basalt M&I Resources that may be suitable for blending with our Orca Sand & Gravel products and could potentially be attractive to additional markets in the future. The additional 330 million tonnes of basalt Inferred Resources suggest that Black Bear could be a multi-generational project that could provide long-term employment and economic benefits to northern Vancouver Island. We are very pleased with the Black Bear discovery and continue to focus on fast-tracking the project rapidly through the permitting and evaluation process. The Black Bear deposit is located at surface and is expected to support a low strip quarrying operation that can produce material similar to the high quality concrete aggregates produced by the Orca Quarry. With additional work, we anticipate that Black Bear could set the stage for the next phase of Polaris’ growth,” stated Ken Palko, President and CEO.

ABOUT THE MINERAL RESOURCE

Initial site investigation, database validation, and construction of the geological model was carried out by Gary Nordin, P. Geo. This geological model formed the basis for resource estimation that was carried out by Wm. (John) Beck, P. Eng. of Beck and Associates GeoConsultants Inc. Gary Nordin and John Beck are both Qualified Persons as defined by NI 43-101.

The Mineral Resource is based on the results from 366.4 metres of core drilling in 5 holes, as well as 7 surface rock samples and detailed geological mapping covering the entire Black Bear resource area. Initial analyses of the tested samples have demonstrated the material to be of a suitable quality to permit the production of various aggregate products to serve a variety of market specifications. Core drill results were used to develop the Measured and Indicated Resources, while the Inferred Resources are derived from outcrop sampling and geological stratigraphy.

Tonnage estimates are based on 15 density measurements recovered from the drill core and taken on twenty (20) metre intervals and applied to a preliminary block model. Blocks classified as Measured Mineral Resources are within 160 metres of 4 closely grouped boreholes towards the southern end of the conceptual Phase I pit outline. Indicated Mineral Resource blocks have a maximum distance to at least 1 hole of 290 m, also being constrained by topography and surface sampling, while Inferred Mineral Resources are derived from geological outcrop mapping in the Phase II and Phase III pit areas and are supported by construction aggregate analytical testing of 5 representative rock samples.

In order to establish reasonable prospects for eventual economic extraction, the Mineral Resources were constrained within an optimized pit shell using Rockworks 17 software. The pit boundary was designed to best represent the identified environmental, social, and engineering parameters. This included identifying setbacks from existing roads, watercourses, and the maintenance of existing tree visual barriers.

The basalt deposit is expected to require only the stripping of a thin layer of overburden and is otherwise continuous throughout the extent of the modelled pit. The project is not currently the subject of a preliminary economic assessment, pre-feasibility study, or feasibility study and additional work will be required to determine the potential economic viability of the project.

The Black Bear tenure is situated in whole or in part within the traditional territories of the Kwakiutl Band and the ‘Namgis First Nation. Polaris intends to work with them as well as with the BC Government and local stakeholders and to apply the same collaborative approach and uncompromising environmental standards that have been a central feature of the development and operation of the Orca Quarry since 2001.
