Senator Minerals Enter Into Standstill Agreement with Respect to Carter Lake Uranium Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 6, 2017) - Senator Minerals Inc. (TSX VENTURE:SNR)(OTC PINK:SNRAF)(FRANKFURT:T1KA) ("Senator" or the "Company") is pleased to announce that the Company has entered into a standstill agreement with Gunnar Minerals Corp. ("Gunnar Minerals") pursuant to which Gunnar Minerals has agreed that the Company will have the exclusive right to acquire a controlling interest in the Carter Lake Uranium Project. The standstill allows the Company to continue to move forward with due diligence on the project with a view to completing the acquisition in the near term.

The Carter Lake Uranium Project is located in the southwestern corner of the Athabasca Basin, Saskatchewan. The project covers approximately 1113 hectares on the Carter Lake Corridor, an exploration zone adjacent to the prolific Patterson Lake Corridor, which hosts two of the most significant uranium deposits in the basin: Nexgen's Arrow Deposit and Fission's Patterson Lake South Deposit. The project lies near the eastern edge of the Clearwater Domain, approximately 21 kilometres northeast of the Patterson Lake property, which has a reported resource estimate of total of 2,011,000 tonnes of 1.83% U3O8 containing 81,111,000 pounds of U3O8 including the R780E High Grade Zone estimated to contain 45,079,000 pounds U3O8 at 18.22% U3O81 and inferred mineral resources are estimated to total 785,000 tonnes at 1.57% U3O8 containing 27,157,000 pounds of U3O8 including the R780E High Grade Zone estimated to contain 13,898,000 pounds U3O8 at 25.06% U3O81. (Fission Uranium Corp. PEA September 14, 2015). Nexgen Energy Ltd. has reported (March 31, 2017) that the Arrow Deposit's Mineral Resource comprises an indicated mineral resource of 179.5 M lbs of U3O8 within 1.18M tonnes grading 6.88% U3O8, and an inferred mineral resource of 122.1 M lbs of U3O8 contained within 4.25 M tonnes grading 1.30% U3O8.

The Carter Lake Uranium Project, which borders Purepoint/Cameco/AREVA's Hook Lake Project to the east, has basement depths estimated at between 400-500 metres, within the general discovery range of the McArthur River mine. The principal exploration target at Carter Lake is approximately 4.7 kilometres of subsurface conductive anomalies, identified in a 2006 MegaTEM survey and a 2008 VTEM survey, both completed by ESO Uranium Corp. The anomalies are interpreted as a conductive horizon, at or above the unconformity and which may be indicative of hydrothermal enrichment.

Completion of the acquisition remains subject to due diligence and negotiation of definitive documentation.
