Regulus Announces Closing of Spin-Out of Aldebaran Resources Inc.

VANCOUVER, CANADA (October 25, 2018) – Regulus Resources Inc. ("Regulus" or the "Company") (TSX-

V: REG) is pleased to announce that, further to its news releases of June 29, 2018, August 30, 2018, September 24,

2018, October 9, 2018 and October 22, 2018 , it has completed the spin-out of Aldebaran Resources Inc.

("Aldebaran"). In addition, Aldebaran has entered into the previously announced joint venture and option

agreement (the "JV Agreement") with Stillwater Canada LLC, an indirect subsidiary of Sibanye Gold Limited,

trading as Sibanye-Stillwater ("Sibanye-Stillwater"), to acquire up to an 80% interest in the Altar Copper-Gold

project in San Juan Province, Argentina ("Altar" or the "Altar Project").

John Black, CEO of Regulus and Aldebaran, commented as follows:

“We are extremely pleased to have completed this transaction, which will allow Regulus to focus on its AntaKori

project in Peru with no further funding obligations in Argentina, and provide Regulus shareholders with equity, at

no cost, in a new well-funded mineral exploration company that will focus on the Altar Project, which management

believes has considerable upside. I would also like to express our appreciation to the many people who assisted us

in this rather complicated process, including our legal counsel, Denton Canada LLP, our financial advisor Maxit

Capital LLP, and the other advisors noted below who participated in the process. I would also like to offer a special

note of gratitude to Route One Investment Company L.P. whose unwavering financial support made all of this

possible. We look forward to creating value for shareholders of both companies through the exploration and

development of these high-potential projects.”

The spin-out was completed by way of a statutory plan of arrangement under the Business Corporations Act

(Alberta) (the "Arrangement") wherein, Regulus transferred its Argentine subsidiaries to Aldebaran in exchange

for 30,331,534 common shares ("Aldebaran Shares") of Aldebaran, which have been distributed to Regulus

shareholders on the basis of one Aldebaran Share for each three Regulus common shares held as of the close of

business on September 28, 2018.

In addition, Aldebaran has completed the previously announced financing ("Financing") with certain investment

funds managed by Route One Investment Company L.P. (such funds, collectively, "Route One"), whereby Route

One subscribed in the aggregate for 31,250,000 Aldebaran Shares at a price of US$0.96 per share for total

proceeds of US$30 million.

Aldebaran has also issued an aggregate of 15,449,555 Aldebaran Shares to Sibanye-Stillwater, representing 19.9%

of the issued and outstanding Aldebaran Shares, and made an upfront cash payment of US$15 million to Sibanye-

Stillwater, all in accordance with the JV Agreement.

There are currently 77,635,959 Aldebaran shares issued and outstanding of which existing Regulus shareholders

(other than Route One) own approximately 29.8%, Route One owns approximately 49.5%, Sibanye-Stillwater owns

19.9% and other Aldebaran shareholders own approximately 0.8%. The Aldebaran Shares are expected to begin

trading on the TSX Venture Exchange under the symbol "ALDE" in approximately 5 business days.
