VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 29, 2017) - Senator Minerals Inc. (TSX VENTURE:SNR) (OTC PINK:SNRAF) (FRANKFURT:T1KA) ("Senator" or the "Company") is pleased to announce that it has commissioned a technical report on the Carter Lake Uranium Project, located on the west side of the Athabasca Basin, Saskatchewan. The report is being prepared as part of the Company's due diligence on the Carter Lake Uranium Project, as well as to rarefy the exploration targets. The report is being prepared under the supervision of Canexplor Management Ltd., which has been actively involved in uranium exploration in Saskatchewan for over ten years.

The Carter Lake Uranium 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 @ 18.22% U3O81 and an inferred Mineral Resources are estimated to total 785,000 tonnes @ 1.57% U3O8 containing 27,157,000 pounds of U3O8 including the R780E High Grade Zone estimated to contain 13,898,000 pounds U3O8 @ 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.

Senator Minerals is a junior mineral explorer focused on uranium exploration in northern Saskatchewan. Senator has entered into an agreement with an arm's-length vendor to acquire a 100-per-cent interest in the Patterson North East (PNE) uranium project, located on the east side of the Athabasca basin in Northern Saskatchewan, the most productive uranium-producing region in the world.
