VANCOUVER, BRITISH COLUMBIA–(Marketwired – Feb. 4, 2016) –

THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO UNITED STATES SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Macarthur Minerals Limited (TSX VENTURE:MMS) (the “Company” or “Macarthur Minerals”) is pleased to announce a non-brokered private placement and that it is assessing opportunities for acquisition of lithium and graphite projects in Australia.

Non-brokered Private Placement

The non-brokered private placement (the “Offering”) will be for up to 15,000,000 units (each, a “Unit”) at a price of CAD$0.02 per Unit (“Unit Price”) for aggregate gross proceeds of up to CAD$300,000. The Unit Price is equal to the closing price of the Company’s TSX Venture Exchange listed shares on February 3, 2016.

Each Unit shall be comprised of one common share in the capital of the Company (each, a “Common Share”) and one whole warrant to acquire a Common Share (each, a “Warrant”) at an exercise price of CAD$0.05 per Common Share for a period of twelve months from the date of issuance.

The Company has obtained approval from the TSX Venture Exchange to waive the CAD$0.05 minimum pricing requirement in accordance with TSX Venture Exchange bulletin dated April 7, 2014 “Discretionary Waivers of $0.05 Minimum Pricing Requirement“.

The closing of the Offering will occur as soon as possible after and subject to receipt of all necessary regulatory approvals including that of the TSX Venture Exchange. The net proceeds from the Offering will be used for working capital purposes, in particular rents and rates for Macarthur’s iron ore projects, salaries for project staff and other project related costs. No part of the proceeds will be used to pay management fees or to pay related parties. The securities issued pursuant to the Offering will be subject to a statutory 4 month plus one day hold period from the date of issuance.

The Company anticipates that insiders will subscribe for Units in the Offering. The issuance of Units to insiders pursuant to the Offering is considered to be a related party transaction subject to TSX Venture Exchange Policy 5.9 and Multilateral Instrument 61-101. According to MI 61-101, such a related party transaction requires a formal valuation and minority shareholder approval, unless exempted. An exemption from the formal valuation requirement is available to the Company, as the Company is not listed on any specified market (as that term is used in MI 61-101). An exemption from the minority shareholder approval requirement is available to the Company as neither the fair market value of the Units issued to, nor the fair market value of the aggregate consideration to be paid by, the Related Parties in connection with the Offering, will exceed 25% of the market capitalization of the Company as of the date hereof.

Lithium and Graphite Acquisition Opportunities

The Company is in the process of assessing opportunities for acquisition of lithium and graphite projects in Western Australia.

The funds raised from the Offering will not be used to pay for the acquisition of projects, which are currently under assessment.
