Sirios signed an Option Agreement for the South and West blocks of its

Cheechoo Property

Montreal, QC – Management of Sirios Resources Inc. (TSX-V: SOI; OTCQB: SIREF)

("Sirios") is pleased to announce the signing of an option agreement on the south and west blocks

of its Cheechoo property (Figure 1) located in Eeyou Istchee James Bay in Quebec, with Electric

Elements Mining Corp. ("EEM"). EEM is new private lithium company jointly created by Osisko

Development Corp. and Osisko Mining Inc. Pursuant to the agreement, Sirios granted EEM the

option to acquire up to a 100% interest in each of the south and west blocks of its Cheechoo

property in return for an investment of $0.5 million, over a period of two years, as described below.

EEM will explore both blocks for lithium and if the option is exercised, Sirios will retain a 1.5%

NSR ("Net Smelter Return") royalty on the southern block.

In addition, if the option is exercised, Sirios will be able to recover, at no cost, 100% of the claims

on which gold mineralization in bedrock reaching a minimum metal factor of 10 g/t per metre has

been identified.

To obtain a 100% interest in the two blocks or, at its option, in one or the other of the two blocks,

EEM must, over a period not exceeding two years:

 Pay an amount of $100,000 to Sirios upon signature;

 Carry out a minimum of $50,000 in exploration work on each of the two blocks;

 Pay an amount of $150,000 in cash and/or shares, with a minimum of 50% in cash, per

block at the request of Sirios.

Sirios will retain 100% of the exploration and exploitation rights for all mineral substances in the

main block of the property, where the Cheechoo gold deposit is located.
