A Primer on High Purity Quartz (HPQ)
The U.S., Canada, and EU have classified silicon as a critical mineral
High-purity quartz (HPQ) is a rare, ultra-refined form of quartz with extremely low impurity levels, making it critical for high-tech applications like semiconductors, and solar panels. Quartz, composed of silicon dioxide (SiO₂), is one of the most abundant minerals on Earth, but only a small fraction of deposits meets the stringent purity requirements for HPQ. HPQ production relies on raw materials with naturally low impurities, as the purification process is both expensive and involves multiple chemical and thermal stages. Even with advanced methods, only select silica deposits can be economically upgraded to HPQ.
Major global sources of high-purity silica include the U.S., Russia, Australia, and Brazil.
Global HPQ production exceeds 220 Kt annually, with Spruce Pine (U.S.), accounting for 90% of supply
HPQ is a highly purified form of quartz, with SiO2 concentrations exceeding 99.997%, produced through rigorous filtration, and purification processes
The features of high-purity quartz, such as exceptional thermal stability, chemical inertness, and high transparency, make it applicable in a wide range of uses, such as semiconductors, solar panels, and optical fibers.
The semiconductor industry, accounting for 55% of market share, is the leading end-user of HPQ, followed by the solar industry
Due to the specialized nature and varying purity requirements of HPQ, it is traded through privately negotiated contracts, rather than on a public exchange.
Asia Pacific dominates global HPQ demand, with a 62% share. While China is a net exporter of silicon and many critical minerals, and metals, it is a net importer of HPQ
Prices are primarily driven by purity, ranging from US$25/t to over US$6k/t
It is estimated that the global HPQ market will grow 7% p.a., from US$1B in 2025, to US$1.7B by 2032, driven by rising demand from the semiconductor, and solar energy sectors
Company Overview
HMR’s business plan is to establish a fully integrated HPQ industrial vertical, managing the entire process from raw material extraction to the final product in solar and energy storage solutions. Solar and energy storage are vital for a clean and reliable energy future, with solar offering renewable power, and storage ensuring consistent availability. We believe this combination is critical in meeting the world's growing demand for electricity.
Formed in 2023. HMR aims to be a leading HPQ materials company through a three-phase business plan
Three Verticals: From Mine to Market
Phase One HPQ Silica Supply
Phase Two Infrastructure & Logistics
Phase Three Revenue & Vertical Integration
Belmonte Silica District Project, Brazil
HMR gained control of its flagship project through a 40-year exclusive lease with CBPM (a government-owned entity in Bahia, Brazil) for silica extraction; royalties are R$50/ton (US$9/t), plus 5% on international sales
Brazil is the third-largest producer of silicon, trailing only China and Russia, and holds one of the world's largest quartz reserves. HMR’s projects in the Belmonte silica district in Bahia are outlined below. A key advantage of the district is its potential for HPQ silica, which has minimal impurities and contaminants, making it ideal for advanced applications. We believe the recent maiden resource estimate on its flagship project is a testament to this potential.
HMR’s Flagship Project: Santa Maria Eterna Silica Sand Lease
Location, Accessibility and Infrastructure
HMR gained control of the project in 2023. Approximately 600 km from Bahia’s capital city, Salvador
Excellent infrastructure in place, including access to electricity, ports, and railway. Proximity to ports is key, as future production will likely be distributed domestically and exported to global markets
Located adjacent to the Jundu silica project, in a region known for hosting long-life mines
Mineralization and Resources
In the 1990s, CBPM drilled 15 holes. HMR followed up with a 254-hole, 2,565 m program from May to September 2024, leading to a recently completed maiden resource estimate
A medium-sized, open-pit resource totaling 64 Mt of high-purity silica sand, grading 99.67% Si02. We believe there is significant resource expansion potential as the deposit remains open at depth, and a new lease remains untested
The project has already received an environmental permit, and HMR expects to receive a mining permit in the coming months.
Development Plans
The company has a near-term path to revenue through a simple quarry operation, including excavation, screening, and washing. The CAPEX for this operation is essentially zero, as the company has formed a partnership (MOU) with a local partner for the extraction, washing, and sorting of silica sand.
Management is evaluating the potential to develop a 120 ktpa silica sand processing plant on-site, aimed at producing HPQ with <100 ppm impurities. Management's preliminary initial CAPEX estimate is <US$20M, with the final estimate to be determined shortly by the company's engineering contractors. At 120 ktpa, we believe the 64 Mt resource could sustain production for over 500 years. Construction is projected to take 6-12 months, with production targeted to commence in H1-2026.
HMR has partnered with researchers at The University of California, Davis (UC Davis) to develop a single-step thermal processing method to purify HMR’s silica, producing HPQ with a purity of 99.999% SiO2. This process avoids harmful chemicals, and energy-intensive procedures, typically used in traditional HPQ production methods. HMR owns the Intellectual Property/IP developed through this partnership.

HMR’s Primary Target Markets & End-User Applications
Solar Market: Brazil
Brazil is a leader in renewable electricity within the G20, with 89% of the country’s electricity generated from renewable sources. Solar power accounts for approximately 7% of Brazil’s total electricity generation, and 22% of Brazil’s total installed electricity capacity, making it the second-largest source of generation, behind hydropower.
Brazil: a G20 leader in renewable energy
Brazil's solar electricity generation is projected to grow at an annual rate of 20.06% from 2025 to 2029 (Source: Statista). The country has seen remarkable growth in its solar PV capacity, expanding nearly sixfold in the past five years. By December 2024, installed capacity is expected to reach close to 55 GW, with projections showing a rise to 97.46 GW by 2028 (Source: Energybiz).
Its is estimated that Brazil’s solar energy market will grow at a rate of 23% during 2025 to 2030
HPQ has diverse applications across the solar industry
Solar Glass Manufacturing
HPQ is an indispensable raw material for the solar industry, playing a crucial role in various stages of solar panel production.
HPQ plays a crucial role in the production of solar glass, a key component in solar panels that enhances sunlight transmission, and protects photovoltaic cells. Currently, the solar glass market is predominantly controlled by Asian producers, particularly in China, from which Brazil imports a substantial share of its requirements.
It is estimated that the global solar glass market will grow from $13B in 2024, to US$197B by 2034, reflecting a 31% CAGR
HMR to build Latin America's first solar glass plant. Secures potential offtake agreements. Strong potential with risks ahead
HMR aims to disrupt this import dependency by establishing Latin America's first solar glass manufacturing facility near the port of Aratu, Brazil. The Brazilian government has implemented a 25% tariff on imported Chinese solar components, including glass, while offering tax incentives for domestic production, creating a favorable environment for HMR's initiative. This aligns with Brazil's expanding solar panel market, and its drive for self-sufficiency in the renewable energy sector.
The company has secured significant potential offtake agreements, including multiple Letters of Intent (LOI) with solar panel manufacturers (current and planned) in Brazil. Sengi Solar and Balfar Solar, two leading Brazilian solar panel manufacturers, have committed to a minimum of 120 kt per year at a price of US$750/t, which is in line with current market prices for imported solar glass in Brazil.
To advance the project, HMR has engaged two consultants to complete a feasibility study. A leading German turn-key glass plant provider has quoted US$165M for a 365,000-tonne per year state-of-the-art glass production plant. HMR anticipates completing the feasibility study by the end of the year, followed by project financing. Construction is projected to take 12 months, with production targeted to commence in H1-2027.
Overall, we believe HMR has a solid plan to capitalize on Brazil's growing solar market, and meet the country's demand for domestic solar glass production. However, as a new company in its early stages, it faces all the execution risks typical of such ventures. The upcoming feasibility study will provide much more clarity on the future prospects of this initiative.
The table below outlines HMR's two other major initiatives.
Homerun Energy: Formed Through Halocell Europe Acquisition (Closed in March 2025)

FRC Projections and Valuation
There are several publicly traded silica juniors with advanced-stage assets, but they are not directly comparable to HMR. Most are pure explorers/developers with no vertical integration plans, and many have higher impurity levels, making their processes more capital-intensive. As a result, we are valuing HMR based on our Discounted Cash Flow models on the two main flagship initiatives: a) HPQ silica production from a potential 120 ktpa operation at the Santa Maria Eterna silica project, and b) the proposed 365 ktpa solar glass manufacturing plant. For the sake of conservatism, we are not assigning any value to the company's other initiatives.
Based on a conservative 20-year mine life, we are valuing the company’s HPQ project at $0.89/share
Below is a summary of our valuation models, including assumptions, key inputs, and sensitivity analysis.
Based on a conservative 20-year mine life, we are valuing the company’s proposed solar glass plant at $1.59/share
Assigning a risk rating of 5 (Highly Speculative)
Based on our review of the company’s projects, and management initiatives, we are initiating coverage with a BUY rating, and a fair value estimate of $2.54/share. We believe HMR presents a notable yet complex opportunity through its ambition to establish a vertically integrated HPQ operation, capitalizing on Brazil's import reliance, and the growing solar and energy storage sectors. Monitoring upcoming milestones, particularly the mining permit, and updates on the proposed glass manufacturing plant, and other solar and energy storage end-user initiatives, will be crucial in assessing HMR's execution viability.
