Brian Leeners (Homerun Resources): The Silica Opportunity
Brian Leeners, CEO of Home Run Resources, discusses his company's vertically integrated high-purity silica sand mining operation in Brazil's Bahia state, explaining how their exceptionally low-iron silica (under 10 ppm) positions them uniquely for solar glass production and advanced technology markets. The conversation covers silica's underappreciated role across solar, photonics, AI, and semiconductor supply chains, and why ex-Chinese silica assets are strategically important. Leeners argues Home Run can compress the typical 15-20 year mine development timeline into 3-5 years through creative capital deployment and vertical integration.
Summary
Brian Leeners, CEO of Home Run Resources, joins the podcast to discuss the company's vertically integrated high-purity silica sand operation in Bahia, Brazil. Leeners, a Canadian entrepreneur with backgrounds in both technology and materials, explains that he identified the asset by Googling 'high purity silica in Bahia' and finding a PhD paper that led him to the district. He describes how the district had been known for 40+ years but remained undeveloped because five fragmented owners couldn't coordinate, and because the logistics hadn't previously supported economically viable extraction. Home Run solved this by bringing industry to the resource rather than moving the resource to industry, and has since assembled control of over 60 million tons within a district estimated at 500 million tons.
The silica deposit is described as globally exceptional, with iron content below 10 ppm after washing, compared to the 100-140 ppm iron content used by Chinese producers for solar glass. Leeners explains the silica quality pyramid: from sandbox-grade material at a few dollars per ton, to ultra-high-purity crucible-grade silica at $10,000 per ton produced only by Sibelco and Quartz Corp from a single source in Spruce Pine, North Carolina. Unlike copper, silica has no public futures market and prices are opaque, requiring producers to build economics from use-case cash flow models rather than spot prices.
Home Run's go-to-market strategy is vertically integrated and sequential. Their washed silica is immediately suitable for solar glass production, and they are building a 365,000-ton-per-year solar glass plant as an SPV, which Leeners says would be a billion-dollar business at full operation. The company plans to progressively purify silica from 3N (99.9%) to 4N and 5N purity, unlocking higher-value markets including photonics, quantum computing substrates, fused silica wafers, and crucibles for silicon production. Processing CapEx is described as relatively modest — the 3N plant is estimated under $50 million — with high margins due to Brazil's cost structure.
Leeners draws a parallel between silica and rare earths as a China-dominated critical material, but argues silica is actually rarer at the high-purity end than rare earths. He notes China's Five Year Plans explicitly identify high-purity silica as a key critical element across solar glass, silicon crucibles, semiconductors, and photonics/quantum computing. He highlights that Indonesia and Egypt have already restricted high-purity silica exports, signaling growing resource nationalism around the material.
On the solar market, Leeners describes China's 'pinch and swell' strategy — flooding global markets with subsidized product to eliminate competition, then rationalizing to extract margin once dominance is established. He notes the world currently produces 80,000 tons of solar glass per day, with conservative projections of 300,000 tons per day by 2036, driven by solar growth and the bifacial panel transition requiring glass on both sides. He argues Home Run's low-iron silica enables antimony-free, extra-clear solar glass that can improve module efficiency, a product no competitor can currently match.
On photonics, Leeners explains that AI's data processing demands are pushing semiconductor interconnects from electrons to light over short distances — an inversion of fiber optics' long-distance use case — and that fused silica is foundational to this transition. He argues the U.S. should be focused on securing high-purity silica for fused silica and photonics leadership rather than trying to rebuild a silicon semiconductor industry. He also discusses the lithium niobate quantum computing stack, which uses multiple silica-derived layers, as another growth vector.
On financing and dilution, Leeners states the solar glass plant will be financed through a U.S.-denominated SPV, so equity dilution will occur at the project level rather than the parent company level. He positions the current $15 million USD market cap as a significant discount to a business that could be worth multiples based on just the solar glass vertical alone, while acknowledging investors must weigh the development timeline. The company trades on the TSX Venture under HMR, the OTC QB in the U.S., and in Germany, with plans to list in Brazil and eventually move to a senior U.S. exchange.
Key Insights
- Leeners claims Home Run's silica washes to below 10 ppm iron content — compared to 100-140 ppm used by Chinese solar glass producers — which he argues makes it the best silica for solar glass in the world.
- Leeners argues that high-purity silica is rarer than rare earths at the top end of the quality spectrum, noting that currently only one geographic source — Spruce Pine, North Carolina — supplies the crucible-grade silica that underpins 95% of global silicon production.
- Leeners describes China's 'pinch and swell' strategy: flooding global markets with government-subsidized product to eliminate competitors, then switching to high-margin extraction once dominance is entrenched — and argues solar is now in the 'pinch' phase.
- Leeners states that China's latest Five Year Plan explicitly identifies high-purity silica as a key critical element across four areas: solar glass, silicon crucibles, semiconductors, and photonics/quantum computing — signaling China's own strategic awareness of silica scarcity.
- Leeners argues the U.S. government should prioritize securing high-purity silica for fused silica and photonics applications rather than attempting to rebuild a silicon semiconductor industry, claiming he told this directly to U.S. government officials.
- Leeners contends that Indonesia, Egypt, and Saudi Arabia have all restricted or are restricting high-purity silica exports, reflecting growing resource nationalism around the material globally.
- Leeners describes the solar glass market growing from 80,000 tons per day currently to a projected 300,000 tons per day by 2036, driven both by solar deployment growth and the bifacial panel transition requiring glass on both module sides.
- Leeners explains that Home Run acquired its controlling position across the Bahia silica district for $3 million USD total, which he presents as evidence of disciplined capital deployment against a strategically significant resource.
- Leeners argues that photonics — moving data via light over short distances inside AI data centers — is rapidly becoming a dominant technology, and that fused silica made from high-purity silica is foundational to this transition, citing recent NVIDIA investments as confirmation.
- Leeners describes a lithium niobate quantum computing chip stack that consists of multiple silica-derived layers (silica substrate, fused silica wafer, silicon processing layer), arguing that silica is the structural foundation of next-generation computing regardless of which technology wins.
- Leeners claims the solar glass plant will be structured as a U.S.-dollar SPV, meaning dilution for that project would occur at the subsidiary level rather than at the Home Run parent company level, protecting existing shareholders.
- Leeners argues that silica is second only to water as the world's most used industrial commodity but that investable, high-purity silica assets are extremely rare — and that almost no investors or even U.S. government officials are aware of silica's strategic importance, creating an information asymmetry opportunity.
