RETRANSMISSION: Rhyolite Resources to Acquire Brothers Project in Suriname

Vancouver, October 14, 2020 - Rhyolite Resources Ltd. (TSXV: RYE) (the "Company" or "Rhyolite") is pleased to announce that it has entered into a definitive share purchase agreement, dated October 13, 2020, with each of the shareholders (collectively, the "Vendors") of 2777662 Ontario Corp ("ONCorp") to acquire all of the outstanding share capital of ONCorp. ONCorp is a privately-held arms-length company which holds an option to acquire an 80% interest in the Brothers Project in Suriname.

Under the terms of the purchase agreement, Rhyolite will issue 15,546,566 common shares to the Vendors in consideration for all of the outstanding share capital of ONCorp (the "Transaction").

Highlights:

• 96-square-kilometer Brothers Exploitation concession is located approximately 140 kilometers south of Paramaribo, the capital city of Suriname and accessible by road and within the same general mineralized lithologic and structural setting as IAMGOLD's Rosebel Gold Mine and Newmont's Merian Mine.
  

• The Brothers Project is an exploitation license, which allows mining with no additional permits. The Project is not in or near any protected areas, and no villages are located within the concession. Brothers is within the area of interest between Newmont and the government of Suriname in their Mineral Agreement.
  

• Brothers is considered one of the more prospective projects in the Guiana Shield with a number of high priority targets supported by 246 grab samples from the extensive small scale mining operations. Of these samples, 84 exceed 1 g/t Au (34%) and 22 exceed 10 g/t Au with a high assay of 105 g/t Au.

• At one mine on the property, small scale underground mining by hand reported 50 kilograms of gold production over 10 months of operation with three underground levels and a fourth being developed. Two samples of tails from the sluice collected during a site visit showed very high gold values of 21.8 g/t and 28.9 g/t, indicating high head grades and low recoveries.

• Another small-scale mine located on the property in saprolite with exposed quartz veins 8 to 10 meters in width delivered assay results from channel sampling with an average grade of 6.48 g/t Au over 10 meters and includes 17.25 g/t Au over 2 meters.

Richard Graham, President and Chief Executive Officer of Rhyolite, commented: "We are excited to expand our portfolio of projects in line with our corporate strategy to seize attractive opportunities. The country of Suriname, within the Guiana Shield, is one of the last under-explored frontiers for tier one gold mines. Suriname has become one of the fastest emerging gold jurisdictions in South America and the Brothers Concession is in the center of an established gold belt hosting large, high grade gold deposits. We look forward to advancing this project to uncover another potential Rosebel or Merian."

Brothers Project

The 96-square-kilometre Brothers Concession (the "Project" or "Brothers") is considered one of the more prospective projects on the Guiana Shield in Suriname. Mining and alluvial mining has occurred on the Concession since 2009 (see Figure 1). Brothers is accessible by road and is located approximately 45 kilometers from Newmont's Merian Mine, which produced 500,000 ounces per year, totalling 1 million ounces in the first two years of production alone (see Figure 2). Brothers is within the same general mineralized lithologic and structural setting as IAMGOLD's Rosebel Gold Mine and the Merian Mine.

Since 2014, samples collected from the Project include 100 channel samples of which 32% are greater than 1 gram per tonne (g/t) gold and 63% of which are greater than 100 parts per million. Three samples exceed 10 g/t with a high of 17.25 g/t. There is a total of 246 grab samples, including 2018 results (see Figure 3). Of these, 84 exceed 1 g/t (34%) and 194 exceed 100 parts per billion (80%). Of these, 22 exceed 10 g/t with a high assay of 105 g/t from the nearby Manse Mine. A sieve analysis demonstrated a value of 135 g/t for the 105 g/t sample.

At the Manse Mine, underground mining by hand of a significant quartz vein, first discovered by alluvial mining, reported 50 kilograms of gold production over 10 months of operation utilizing a small shaft. There are currently three underground levels at Manse with a fourth currently in development. The operator reported grades of 30 to 40 g/t on levels one and two, and approximately 20 g/t on the third. However, these results have not been independently verified (see Figure 4). Two samples of tails from the sluice collected during a site visit showed very high gold values of 21.8 and 28.9 g/t, indicating current processing techniques are highly inefficient.

The Savero Project has been a primary target at the Brothers Concession, with the intent of conducting small-scale mining in the saprolite. In March 2015, the southwestern wall showed a zone of parallel to sub parallel, asymmetric quartz reefs that can be classified as tension gashes. These veins have been the main target and are 8 to 10 meters in width. Quartz veins intercepted on the southern wall are white, oxidized and include spots, banded and massive tourmaline, especially near the selvages. Assay results from channel sampling across quartz veins on the northeastern wall of the pit show an average grade of 6.476 g/t over 10 meters and include a high grade sample of 17.25 g/t over 2 meters. Assay results from tailings shows a value of 8.18 g/t (see Figure 5).

The greenstone belt of the Guiana Shield is estimated to host approximately 110 million ounces of gold from Venezuela to Brazil.^* The greenstone belt is part of the Trans-Amazonian orogenic cycle which represents a major deformational event centered around two billion years ago. The rocks of the Trans-Amazonian orogenic cycle and equivalent are a major source of gold production and resources in both South America and Africa, which were linked together prior to the opening of the Atlantic Ocean.

At Brothers, gold is associated with quartz veins that contain tourmaline and iron sulfides. Surrounding rocks are bleached or altered granitic rocks or felsic dikes or both. The vein sets appear to be brittle deformation with minimal shearing or ductile deformation. In the sedimentary rocks within a major shear zone are a second geologic setting that appears to contain potential gold deposits on the Brothers Concession. A simple interpretation of the magnetic survey flown by Terraquest in 2012 is provided in Figure 6.

Highlights of the Transaction

Upon closing of the Transaction, Rhyolite shall assume ONCorp's right to earn up to an 80% interest in the Brothers Project, which right is exercisable by completing the following:

• US$200,000 cash payment within six months of the closing of the Transaction, for a 20% interest in the Project.

• Drill 3,000 meters with minimum committed work capital of US$1 million within 18 months of the closing of the Transaction and make a US$300,000 cash payment for a 40% interest.

• Drill an additional 10,000 meters with minimum committed work capital of US$3.5 million within 42 months of the closing of the Transaction, and make a US$400,000 cash payment for a 60% interest. If the Company does not earn a 60% interest in the Project, it will return the shares earned to date.

• Deliver a preliminary economic assessment ("PEA") within 66 months of closing of the Transaction and payment of US$500,000 for a 70% interest.

• Deliver a feasibility study and payment of US$1.25 million, for an 80% interest.

• Upon commencement of commercial production at Brothers, make a US$2.5 million cash payment.

• Upon closing of the Transaction, the Company is entitled to purchase a 0.5% net smelter return royalty for US$2 million.

The Company is at arm's length from each of ONCorp and each of the Vendors. In consideration for all of the outstanding share capital of ONCorp, the Company has agreed to issue 15,546,566 common shares to the Vendors. In connection with completion of the Transaction, the Company does not expect to assume any material liabilities other than in connection with the acquisition of an interest in the Brothers Project, nor does it expect to devote the majority of its working capital or resources to the development of ONCorp or the Brothers Project. As a result, the Transaction does not constitute a fundamental acquisition for the Company, within the policies of the TSX Venture Exchange. The Transaction will not result in the creation of a new insider or a change of control of the Company, within the meaning of applicable securities laws.

Completion of the Transaction remains subject to the approval of the TSX Venture Exchange, and other conditions customary for a transaction of this nature, and cannot be completed until such conditions have been satisfied. The Transaction is expected to close by October 30, 2020. No finders' fees or commissions are payable in connection with the Transaction.
