Millrock Completes Drill Program on Behalf of PolarX at Stellar Copper-Gold Project, Alaska

VANCOUVER, BC--(Marketwired - October 04, 2017) - Millrock Resources Inc. (TSX VENTURE: MRO) (OTCQX: MLRKF) ("Millrock") is pleased to announce that it has successfully completed a late-season drilling program on the Stellar copper-gold project in Alaska. The work was executed by Millrock on behalf of PolarX (ASX: PXX) ("PolarX") (previously Coventry Resources (ASX: CYY)).

Millrock sold the Stellar project to Coventry in August 2017 in a transaction announced here, and Coventry subsequently changed its name to PolarX. Millrock presently owns approximately 10.7% of the issued and outstanding shares of PolarX and is entitled to certain milestone and royalty payments.

The drilling program's primary objective was to establish a modern resource for the Zackly deposit that meets the standards of the Australian Joint Ore Reserves Committee for mineral resource reporting. A historic high-grade copper-gold resource had been previously reported by prior workers at Zackly, which is situated on the Stellar claim block and is detailed in this summary description.

The results of visual observations of drill core samples are summarized in the PolarX press release which can be viewed at this link.

Drill core recovery techniques and samples acquisition, handling and assay methods are clearly stated in the PolarX press release and it is anticipated that initial assay results will be received in October.

The technical information within this document has been reviewed and approved by Gregory A. Beischer, President, CEO and a director of Millrock Resources. Mr. Beischer is a Qualified Person as defined in NI 43-101.
