MILLROCK COMPLETES DRILL PROGRAM ON BEHALF OF

POLARX AT STELLAR COPPER-GOLD PROJECT, ALASKA

VANCOUVER, BRITISH COLUMBIA, October 4, 2017 - Millrock Resources Inc. (TSX-V:

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.
