Solaris Copper Options the Tamarugo Property from Minera Freeport-McMoRan South America Limitada

All amounts are in United States dollars unless otherwise indicated

July 3, 2019 – Vancouver, BC – Solaris Copper Inc. (“Solaris” or the “Company”) is pleased to announce that

its wholly-owned subsidiary, Solaris Copper Chile SpA (“Solaris Chile”), has entered into a definitive earn-in

option agreement (the “ Option Agreement”) with Minera Freeport-McMoRan South America Limitada

(“Freeport”) with respect to Freeport’s Tamarugo property (“Tamarugo”) in Chile.

Tamarugo is a grass -roots copper porphyry target consisting of approximately 5,100 hectares strategically

located in northern Chile approximately 85 kilometres northeast of Copiapo and approximately 65 kilometres

southwest of Codelco’s El Salvador Copper Mine.

Greg Smith, CEO of Solaris, commented, “We are pleased to build on our existing relationship with Freeport

in Chile as they advance our Ricardo property and we commence exploration at Tamarugo. Tamarugo was

selected for Solaris by J. David Lowell, the leading expert on copper porphyry exploration. Tamarugo is in a

jurisdiction hosting many large-scale gold and copper mines, several of which were discovered by Mr. Lowell,

and both he and Jorge Fiero, the Company’s Vice President of Exploration, will manage the exploration

program at Tamarugo.”

Option Agreement Overview

Pursuant to t he Option Agreement , Solaris Chile can earn up to a 75 % interest in Tamarugo for gross

expenditures of $5.5 million plus the delivery of a pre -feasibility study for a mine at Tamarugo, subject to a

back-in right in favour of Freeport.

A summary of the key terms is as follows:

• To ea rn an initial 51% interest in Tamarugo, Solaris Chile will spend $4. 0 million in exploration

expenditures over four years with $250,000 spent in year one, $350,000 in year two, $1.9 million in

year three and $1.5 million in year four.

• Within 60 days of Solaris Chile earning the initial 51% interest in Tamarugo, Freeport may exercise a

back-in right to reacquire 11% of Tamarugo by paying to Solaris Chile $12 million (the “Back- in

Right”). Freeport will then sole fund all exploration expe nditures until either completing a pre -

feasibility study for a mine at Tamarugo or spending a total of $50 million within 10 years of exercise

of the Back-in Right. Should Freeport not either complete the pre-feasibility study or spend a total of

$50 million within 10 years of exercise of the Back-in Right, Freeport will pay to Solaris Chile $1 million

annually until complete.

• Should Freeport elect not to exercise the Back -in Right, Solaris Chile can elect to earn an additional

24% interest in Tamarugo by spending an additional $1.5 million in exploration expenditures in year

five and delivering a pre-feasibility study for a mine at Tamarugo by the end of year seven.

warrants exercisable for three years into common shares of Solaris at an exercise price of C$0.35 per share

and an additional 1,000,000 common shares of Solaris upon making a discovery of potentially economic

mineralization at Tamarugo.

Private Placement Financing

(the “Private Placement”). Pursuant to the Private Placement, Solaris issued 2,452,000 common shares of the

Company at a price of C$0.25 per common share for gross proceeds to the Company of C$613,000. No fees
