Carmax Mining Corp. Increases Size of Eaglehead Project

Highlights of the proposed transaction are:

• Approximately 2,400 ha in 3 mineral tenures located contiguous to the northern boundary of the Eaglehead project
• Purchase price of $15,000 and 3.9 million common shares of Carmax Mining Corp.
• Vendor will retain a 2% Net Smelter Return (“NSR”) on production from the project
• Carmax retains the right to re-purchase up to 1.5% of the 2% NSR for a purchase price of $1.0 million.

“We are very pleased to have secured these mineral tenures that are strategically located in an area whose exploration significance was identified in late 2017,” Jevin Werbes, President & CEO of Carmax commented. “On closing this transaction, our company will acquire the balance of a large magnetic and potassic signature that is interpreted to have potential to host porphyry copper style mineralization. A preliminary mapping and prospecting program is planned for 2018, to assess the porphyry potential of these properties.”

Basis for Acquisition:

Compilation work, completed on the Eaglehead project in late 2017, indicates that a large portion of the Eaglehead intrusive exhibits distinct magnetic and potassic signatures (12 km by 5 km and 8 km by 2 km, respectively). These signatures are interpreted to represent magnetite destructive and potassic alteration - features typically associated with a porphyry copper system. The compilation work further shows that parts of these signatures are located outside the Eaglehead project in the area underlain by the acquired mineral tenures and that the magnetic and potassic signatures underlying the acquired tenures are similar to those on Eaglehead. Together, these characterize a large, untested exploration target located immediately north of the Pass and Camp zones (magnetic and potassic signatures coincident with positive chargeability, copper and molybdenum in soil anomalies, and copper mineralization in outcrop and subcrop, over a 3 km by 2 km area).

About the Eaglehead Project

The property is located in northwestern British Columba and hosts an NI 43-101 Inferred Mineral Resource estimated to total 102.5 million tonnes at an average grade of 0.29% Cu, 0.010% Mo and 0.08 g/t Au. The Technical Report, filed on Sedar at www.sedar.com was prepared by RPA Inc. (see news release dated May 16, 2012). The resource was estimated at a cut-off grade of 0.16% CuEq, to contain approximately 662 million pounds copper, 22 million pounds molybdenum, and 265,000 ounces gold. The Inferred Mineral Resource is contained within two conceptual open pits covering the East and Bornite zones.
