Vancouver, British Columbia, August 1, 2017 – Silverstone Resources Corp. (“Silverstone” or the
“Company”), is pleased to announce that it has entered into an option agreement dated as of August 1,
2017 (the “Option Agreement”) with Magnus Minerals Ltd. (“Magnus”), a company incorporated under
the laws of Finland, whereby Magnus has granted Silverstone an exclusive right and option to earn and
acquire a 100% interest in each of the Riikonkoski (East and West), Jeesiö (including Jeesiö West) and
Ylöjӓrvi (including Oks) projects (the “Projects”), which are located in Finland and currently owned by
Magnus (the “Option”).

Pursuant to the Option Agreement, Silverstone is required to (among other things): (i) issue 6,000,000
common shares to, or as directed by, Magnus; (ii) incur and fund exploration expenditures on or in respect
of the Projects in the aggregate amount of $2,500,000 ($300,000 by August 31, 2018; $600,000 by August
31, 2019; and $1,600,000 by August 31, 2020); (iii) grant a 1.5% net smelter return royalty (the “NSR”) in
favour of Magnus; and (iv) make an aggregate amount of $250,000 in cash payments to Magnus ($30,000
by August 31, 2018; $60,000 by August 31, 2019; and $160,000 by August 31, 2020).

The Option Agreement also provides that if Silverstone exercises the Option, Silverstone will be obligated
to pay Magnus an additional payment equal to the value of 1,000 troy ounces of gold, within 12 months of
the commencement of commercial production. Pursuant to the Option Agreement, Magnus has agreed to
provide mineral exploration services to Silverstone.

At any time, Silverstone may elect to stop making payments under the Option Agreement, which would
result in the termination of the Option Agreement. Upon termination of the Option Agreement,
Silverstone would forego all of its rights to the Projects and any payments (including the issuance of
shares) already made to Magnus or expended on the Projects.

The NSR provides that Silverstone will pay Magnus a 1.5% NSR on minerals mined or produced from the
Projects. Silverstone will have the right within 90 days of a positive feasibility study on one (or more) of
the Projects to reduce the NSR by 0.5% to a 1% NSR on such Project. To exercise this right, Silverstone
will need to pay Magnus an amount equal to the value of 1,000 troy ounces of gold. The NSR also
provides that the NSR deductions are capped at 10% of the total revenue from the mined products
(calculated on a quarterly basis).

In connection with entering into the Option Agreement, Mr. Walter Coles has resigned as President, CEO
and a director of the Company and Ms. Barbara Broughton has resigned as a director of the Company. Carl
Löfberg, Managing Director of Magnus, has been appointed as a director and the President and CEO of the
Company and Patrick Highsmith has been appointed as a director of the Company. Joe Mullin will remain
a director of the Company.
