Metals Purchase Agreement (“PMPA”) announced on August 10, 2017, results in a total financing package

exceeding C$100 million. The expanded financing package with Wheaton provides capital towards the

acquisition, exploration and development of the high grad e Kutcho copper -zinc-silver-gold project

(“Kutcho Project”) as follows:

1. Up to C$20 million convertible term debt loan and participation of up to C$4 million in an equity

financing to fund the acquisition (the “Acquisition”) of the Kutcho Project from Capstone Mining

Corp. (“Capstone”) previously announced on June 15, 2017.

2. US$7 million advanced on an early deposit basis under the PMPA to fund completion of the

feasibility study and permitting-related expenditures on the Kutcho Project.

3. US$58 million advanced as part of the PMPA towards funding the construction of the Kutcho

Project.

“The increased proposed financing package with Wheaton represents another significant milestone towards

the completion of the Acquisition and development of the high grade Kutcho Project” stated Vince Sorace,

President and CEO of Desert Star. “Wheaton will be a strong technical and financial partner for Desert Star

as we move aggressively forward in expanding the Kutcho Project and towards a production decision.”

“The Kutcho Project is ideally suited for Wheaton’s early deposit stream structure as a source of financing,”

said Randy Smallwood, President and Chief Executive Officer of Wheaton Precious Metals. “While Desert

Star’s recent prefeasibility study shows that this project already has very good economics, we also believe

there is excellent potential for expansion and exploration.”

 Mineralization at the Kutcho Project comprises three “Kuroko -type” volcanic massive sulfide

(“VMS”) deposits aligned in a westerly plunging linear trend. The largest deposit, Main, comes to

surface at the east end of the trend, with Sumac followed by Esso down plunge to the west.

a currency exchange rate of 0.75 USD/CAD

2 A Probable Mineral Reserve is the economically mineable part of an Indicated Mineral Resource, and in

some circumstances a Measured Mineral Resource, demonstrated by at least a Preliminary Feasibility

Study. This study must include adequate information on mining, processing, metallurgical, economic and

other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.

3 Measured and Indicated Resources are inclusive of Probable Mineral Reserves. Mineral Resources are

not Mineral Reserves and do not have demonstrated economic viability.

4 The economic analysis contained in the 2017 PFS does not include inferred resources.

5 Inferred mineral resources are estimated based on limited geologic evidence and sampling, sufficient only

to imply but not verify geological and grade or quality continuity.
