Rogue Announces Optimized PEA: 75% Capex Reduction, Estimated Payback within One Year for Silicon Ridge Project

TORONTO, ON--(Marketwired - May 23, 2017) -

  • Updated Resource: includes Measured & Indicated Resource of 7.7M tonnes grading 98.62% SiO2; Inferred Mineral Resource estimated at 2.1 Mt grading 98.66% SiO2
  • Updated Mine Plan: incorporating less overburden and more detailed waste delineation
  • Updated Capex Plan: shifting to Direct-Ship ("DSO") drops pre-production capital requirements to $3.5M (including $806K contingency) and models an after-tax payback of less than one year1
  • Optimized PEA: indicates a base case pre-tax IRR of 157% and NPV (10% discount rate) of $33.8M
    (after-tax NPV10% of $23.4M and IRR of 132%)2
  • Rogue continues to advance its Plan for Silicon Ridge; focused on finalizing permitting and completing ongoing negotiations, including with potential material buyers and project financiers
  • Corporate Update Conference Call scheduled for Thursday May 25th, 2017

(1) All monetary values are stated in Canadian Dollars unless otherwise noted.
(2) The PEA is preliminary in nature and includes inferred mineral resources that are too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that PEA results will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

Rogue Resources Inc. (TSX VENTURE: RRS) ("Rogue" or the "Company") is pleased to report the results of an optimized Preliminary Economic Assessment ("PEA") on its 100% owned Silicon Ridge Project (the "Project"), located approximately 42 km north of Baie-Saint Paul, Québec, and 4 km northeast of Sitec's operating silica quarry. The PEA, prepared by SNC-Lavalin ("SNC"), integrates optimization work completed over the past six months and plans for direct-shipping material from the contract operator's crushing and screening. The updated PEA uses a new DSO pit constrained Measured resource of 2.5 million tonnes ("Mt") grading 98.62% SiO2, Indicated resource of 5.3 Mt grading 98.62% SiO2 and an Inferred mineral resource of 2.1 Mt grading 98.66% SiO2 and was initially modeled with a 20-year mine life and 200,000 tonnes mined per year. The technical report supporting the PEA (the "PEA Technical Report") will be filed on SEDAR within 45 days.

"This Optimized PEA calculates the excellent potential of the Silicon Ridge project as a near term, ultra-low capex production asset," said Sean Samson, President and CEO of Rogue. "Shifting to DSO is expected to create a compelling return and with minimal dilution, the project has attractive potential economics. We are excited by these results and continue to move forward, advancing the permitting and importantly, working towards partnering with buyers. Rogue continues to execute our Plan, methodically de-risking and moving towards a Development Decision"

Resource Summary

The mineral resource estimate, upon which the PEA is based, includes a pit constrained measured resource of 2.5 Mt grading 98.62% SiO2, indicated resource of 5.3 Mt grading 98.62% SiO2 and an inferred resource of 2.1 Mt grading 98.66% SiO2. The resource estimate includes resources from three zones referred to as the South West, Centre North and North East zones. A significant portion of the estimate is derived from the South West Zone. All zones are open along strike and down dip and have potential for expansion.

Highlights of the Optimization

Between the Q3 2016 PEA and this updated PEA, Rogue has refined the in-pit resource, including improved definition of the internal waste zones, reduction of the overburden cover on the South West Zone and reduced capital expenditure requirement by over 70% reflecting the transition from full processing on site, to focusing on a DSO model.

Reduction of the overburden covering the South West pit that was inferred by the ground penetrating radar survey and verified by the identification of quartzite outcrops resulted in the removal of 222 m3 of overburden from the estimate on the South West Zone (see press release dated January 5, 2017). This reduction represents a potential savings of approximately $1.3 million over the life of the project.

The shift to a DSO model, resulted in the elimination of the onsite processing facility and power line and reduced the estimated CAPEX costs from $13.1 million to $3.5 million. This represents a reduced amount of pre-development work required and simplifies the process for generating salable products. It should be noted that if customers are developed for higher value materials that off-site processing options will be considered by the Company as markets are developed.

End use markets- Commodity and Specialized

In its analysis, released on April 25 and July 13, 2016, Dorfner ANZAPLAN identified a number of potential end uses for the product from the Silicon Ridge deposit (see summary of the April 2016 metallurgical report, available on Rogue has targeted two broad groups of markets: "Commodity" and "Specialized".

The Commodity group will be direct-shipped from Silicon Ridge as lump product, after selective quarrying (led by the on-site Rogue team), primary crushing and screening by the Contract Operator of the quarry to a size as required to meet the specification for ferrosilicon and metallurgical grade silicon producers (averages between 20mm to 120mm). Samples of this material prepared by Dorfner ANZAPLAN, after a primary crush and screen, has already been tested by both ferrosilicon and silicon metal producers.

The Specialized group will require secondary processing (now not included as part of the direct-ship model planned for Silicon Ridge), which the Company will look to arrange offsite with a partner. This material will target: quartz countertops, specialty glasses, specialty coatings, engineered stone, silicon carbide, fused silica and sodium/ potassium silicate.

It is anticipated that the Commodity group will be higher volume and lower priced than the Specialized group, which will represent less volume but garners a higher price for the material. This PEA draws on pricing for only the Commodity group, using a volume mix and target prices for both ferrosilicon and metallurgical grade silicon producers. Sales into the Specialized markets would represent upside to the Base Case and sales of material currently counted as waste.

The Company is in discussions with end use buyers from across both the Commodity and Specialized groups, partner processors with whom Rogue could further process the material with a secondary crush and screen of its material and distributors with relationships across various Specialized markets.
