SOI Sirios Resources Inc

Management of SIRIOS RESOURCES INC. (TSX-V: SOI) is pleased to announce the signing of a property option agreement with Sumitomo Metal Mining Canada Ltd, (Sumitomo), pursuant to which has agreed to grant to Sumitomo an option to acquire up to an 80% interest, following an investment totaling $14.8M on the Aquilon gold property, located in Eeyou Istchee James Bay in Quebec.

Dominique Doucet, chief executive officer of Sirios, stated: "We are honoured and very pleased to start working with Sumitomo to kick off a rigorous and systematic exploration program on the Aquilon property. We believe that this property is very prospective and remains underexplored considering the variety of favourable geological contexts in which numerous high-grade gold showings have been discovered. We rank Aquilon as a high-priority project for Sirios and we look forward to advancing the project with our partner having the financial and technical capacities to develop the numerous discoveries into an important mining project."

Summary of the Option agreement

Pursuant to the agreement, Sumitomo can earn an initial 51% interest in the project by paying a sum of $200,000 at signing to Sirios and incurring an aggregate of $4.6 million in mineral exploration expenditures, on or before the third anniversary of the option agreement. Sirios will be the operator during this earn-in period, entitled to a 10% management fee. A firm commitment of $1.6-million will be spent on the property during this earn-in period.

Sumitomo can earn an additional 29% interest in the project, for an aggregate of 80%, by incurring an additional aggregate of $10 million in mineral exploration expenditures, on or before the sixth anniversary of the option agreement.

Following the earn-in of an 80% interest, Sumitomo and Sirios will form a joint venture in respect of the project. In the event a joint venture participant's interest is diluted to below 10%, it will convert its joint venture interest to a net smelter return (“NSR”) royalty of 2%.
