Company Overview

Sio has approximately 15.2 billion tonnes of in situ high-purity silica including an estimated ~146 million tonne measured and indicated resource and an estimated ~345 million tonne inferred resource and intends to initiate a mining plan that ensures a comprehensive and active environmental stewardship over the years to come. Once the processing facility becomes operational, Sio expects to become a leading environmentally friendly producer of high-purity quartz silica, a unique natural resource and critical mineral. Sio plans to leverage its patent-pending extraction process using proven technology to extract and process silica that exceeds 99.9% purity, providing a significant cost advantage within its industry. Sio's extraction method will not require truck traffic, surface mining, tunneling, dust generation, or chemical cleansing. In combination with its extraction and processing facility using renewable electricity, natural gas, and efficient processing, Sio expects to make considerable inroads to contribute to a low carbon future. Anticipated applications for Sio's high-purity quartz silica include photovoltaics, solar panels, semiconductors, electronics and batteries.

Global decarbonization drivers, regulatory changes, energy transition, and major anticipated semiconductor investments in North America are all expected to be significant catalysts driving demand and creating a robust long-term growth outlook for Sio's high-purity quartz silica products. Sio intends to use proceeds from the transaction to complete the construction of Phase 1 of its facility in Winnipeg, Manitoba, which it expects to complete less than 18 months after Closing. Based on signed and pending customer agreements, all production at Phase 1 is expected to be fully contracted.

Sio Investment Highlights:

• Expects to become a leader in the rapidly expanding high-purity quartz silica industry with no current plans to rely on government subsidies.
• High-purity quartz silica currently represents a $30 billion total addressable market by 2030 for photovoltaics, solar panels, semiconductors and batteries.
• With 146 million tonne measured and indicated resource and 345 million tonne inferred resource, Sio's development plan has a multi-generational resource life.
• Net Present Value of ~$3.9 billion according to engineering estimates from Stantec, based on sustainable mining practices and only a portion of available resources being mined over a 25-year mine life.
• With approximately $150 million of gross capital and additional $10 million expected flow-through equity, Sio anticipates to be fully funded and fully permitted by government authorities at Closing to complete Phase 1 of its production facility.
• Strong demand for high-purity quartz silica with 100% of Phase 1 of its production facility fully allocated under signed and pending offtake agreements/MOUs and marketing agreements.
• Significant cost advantage through efficient mining, extraction, processing and energy utilization to achieve quartz silica purity that exceeds 99.9%.
• Location of production facility creates logistical and rail advantages with easy access to ports on both coasts and closer than competitors to several important markets within North America.
• Low capital intensity and robust operating economics are expected to deliver attractive returns to all stakeholders.
• As published in its annual sustainability reports, Sio strives to be an ESG leader in the industry with what is expected to be one of the world's most environmentally friendly silica mining operations, given no harmful chemical wash process, no tailings pond, no open pit and no silica dust concerns from mining operations.
• Highly experienced leadership team and a board of directors with a proven record of creating shareholder value.

Commentary

"We are excited to partner with Pyrophyte to become a leading producer of high-purity quartz silica," said Feisal Somji, Chief Executive Officer of Sio. "Our streamlined approach to creating environmentally responsible solutions has attracted high profile strategic alliances, which puts us at an important inflection point in our growth trajectory. These solutions follow the Manitoba Clean Environment Commission's recommendations, and the Company is working with the Province of Manitoba to finalize an extraction license that will exemplify the commitment and practices of the Company to be a leader in environmental protection. We will continue to work with the Province of Manitoba and its stakeholders to put the Province on the global stage as a major contributor to achieving global net zero targets through decarbonization initiatives that require high-purity silica. The combination of being fully funded and fully permitted is expected to fuel the next phase of our expansion in high-purity quartz silica extraction and processing. We believe that our combination with Pyrophyte will allow us to scale our production to meet strong customer demand and expand our high-purity quartz silica products to a wide range of applications, such as solar panels, semiconductors, and lithium-silicon batteries, with a long runway for profitable growth in the years ahead. We believe that this Business Combination will put Sio in a position to execute further on our strategic priorities and to support our growth over the long-term."

Chairman of Pyrophyte, Dr. Bernard J. Duroc-Danner, said, "Sio's extensive high-purity quartz silica deposit just south of Winnipeg Manitoba is a remarkable gift of nature. Based on Stantec's report, the deposit is very large and exceptionally consistent throughout. The silica ore comes out at naturally occurring high-purity levels with very low levels of contaminants. The deposit is very shallow allowing for a production process which is exceptionally simple, very low cost and environmentally low impact. The beneficiation needs are minimal, consisting of just a magnetic separation process and washing. No chemicals are required in the entire extraction and beneficiation processes while reclamation postproduction is immediate. We believe that Sio's supply of high-purity quartz silica will benefit from very strong secular demand growth trends in North America and worldwide. Located next to extensive railroad infrastructure, the deposit is ideally located for ease of railway transportation to the West, South and East. Once operational, we expect Sio's facility to combine an ideal transportation location, very low ore production costs, strong secular growth trends in demand and low-impact environmental footprint. We searched long and hard for the right candidate to combine with Pyrophyte and its energy transition mission. Sio fulfilled all our criteria. We are proud to join Sio on its journey to supply what is becoming in many countries around the world one of the most important strategic minerals for the world's energy transition."

Christopher Abbate, Co-Head of Riverstone Credit Partners, noted, "We are excited to support Sio in its mission to deliver this critical mineral that is required by a number of key growth areas, from semiconductors to several key industries driving decarbonization, among others. As we evaluated the opportunity, we were particularly drawn to its vast, high-quality resource, with its low-cost development, guided by a high-quality management team that can draw upon the considerable experience from the Pyrophyte team in growing companies. We look forward to the bright future ahead."

Transaction Summary

The terms of the Business Combination imply an enterprise value of $708 million and equity value of $758 million for the combined company. Approximately $150 million of gross capital, comprised of equity, debt, royalties and Sio's cash on hand, has been secured from a variety of institutional and individual accredited investors, including a credit facility provided by Riverstone Credit Partners, and other financing from HITE Hedge Asset Management and a large Canadian pension fund, and an additional $10 million is expected to be secured from flow-through equity from a variety of individual accredited investors, to support the construction of the first phase of its extraction and processing facility. Availability under the credit facility with Riverstone Credit Partners is subject to certain conditions. In an effort to further strengthen its capital base and reduce debt levels, Sio and Pyrophyte may raise additional equity capital through incremental PIPE investments along with the potential contribution of up to approximately $97 million of cash currently held in Pyrophyte's trust account, subject to redemptions by Pyrophyte shareholders that have not entered into non-redemption agreements.
