NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

IDM Mining Ltd. (TSX VENTURE:IDM) (“IDM” or the “Company”) is pleased to announce that is has increased the size of its previously announced private placement to $10,000,000.

Pursuant to an amended agreement, the syndicate of agents co-led by Haywood Securities Inc., Red Cloud Klondike Strike Inc. and Medalist Capital Ltd. (the “Agents”) will sell, on a best-efforts basis, the brokered portion of the private placement.

The private placement has been increased to up to 66,666,667 non-flow-through units (“Common Units”) and up to 36,363,636 flow-through units (“Flow-Through Units” and together with the Common Units, “Units”) at a price of $0.09 per Common Unit and $0.11 per Flow-Through Unit, for aggregate gross proceeds of up to $10.0 million. The Agents will also have the option (the “Agents’ Option”) to sell up to an additional 15.0 million Common Units.

Each Common Unit will consist of one common share of the Company (a “Common Share”) and one-half of one transferable share purchase warrant (each whole share purchase warrant, a “Warrant”), with each Warrant entitling the holder thereof to acquire one Common Share at a price of $0.15 per Common Share for a period of twenty-four (24) months following the date of issuance. Each Flow-Through Unit will consist of one flow-through Common Share and one-half of one Warrant.

The Company will pay to the Agents and certain finders a cash fee equal to up to 7% of the gross proceeds raised from the sale of applicable Units and warrants equal to up to 7% of the number of applicable Units. Each such warrant will entitle the holder to purchase one Common Share at a price of $0.15 for a period of twelve months following the date of issuance.

The offering will take place by way of brokered and non-brokered private placement. The number of Common Units and Flow-Through Units sold in the offering may be reallocated by the Company. A maximum of 126,111,111 Units are issuable under the offering, which assumes that the maximum gross proceeds are raised through the issuance of Common Units only and the Agent’s Option is exercised in full.

Closing of the offering is subject to receipt of applicable regulatory approvals including approval of the TSX Venture Exchange. The securities issued will be subject to the standard four month hold period under Canadian securities laws and the policies of the TSX Venture Exchange.

The Company intends to use the net proceeds of the Offering for the following:

• a 5,000 meter underground core drilling program to expand and upgrade the high grade underground gold resource at the Red Mountain Project (the “Project”), located near Stewart, BC.
• advance the permitting, field studies and environmental assessment of the Project with the goal of submitting a Project Application report to the BC Environmental Assessment Office (BCEAO) and the Canadian Environmental Assessment Agency (CEAA) in Q4 of 2016. This would potentially allow for a project approval to be secured in 2017.
• completion of engineering, field studies and a Feasibility Study on the Project, and
• general working capital purposes.

The objective of these programs is for the Company to be in a position to make a Final Investment Decision on the Project in 2017.

This press release does not constitute an offer to sell or the solicitation of an offer to buy nor shall there be sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful, including in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the “1933 Act”) or any applicable securities laws of any state of the United States and may not be offered or sold in the United States, or to, or for the account or benefit of a U.S. person (as defined in Regulation S 2 under the 1933 Act) unless registered or pursuant to an available exemption from such registration requirements.
