Silica Sand Mining Groundwater Study: Alberta Company Partners with U of Manitoba on Experimental Research

Alberta Company and University of Manitoba Launch Groundwater Monitoring Research

In a significant development for environmental research in Canada, Calgary-based Sio Silica has announced a partnership with the University of Manitoba to develop an experimental groundwater monitoring system. This collaboration focuses on the companys proposed SiMBA silica sand extraction project near Vivian in southeastern Manitoba. The initiative aims to create a scientifically rigorous, non-invasive network to track aquifer health in real time, addressing longstanding community concerns about potential impacts on local drinking water sources.

The partnership, revealed on February 11, 2026, involves a feasibility study led by University of Manitoba Associate Professor Ricardo Mantilla. It represents a proactive step toward data-driven resource management, potentially benefiting not just this project but broader water stewardship efforts across the province. Sio Silica President Carla Devlin emphasized that the effort goes beyond their operations, positioning it as a tool for responsible development informed by transparent science.

This move comes amid renewed scrutiny of the project, which was previously denied an environmental licence in 2024 due to risks associated with groundwater quality and subsurface stability. By integrating academic expertise, the partners hope to demonstrate how innovative technologies can mitigate extraction risks while advancing hydrological knowledge.

Silica Sand: A Critical Mineral Driving Green Technologies

Silica sand, or high-purity quartz sand, is a foundational material in modern industry. Composed primarily of silicon dioxide (SiO2), it exceeds 99.9% purity in premium grades like those targeted in Manitoba. Its low iron content makes it ideal for producing photovoltaic solar panels, fiber optic cables, lithium-ion batteries, medical glass, and semiconductors—key components in the global shift to renewable energy and digital infrastructure.

Canada sits on vast deposits, particularly in Manitoba's Winnipeg Formation, a sandstone aquifer holding an estimated 15 billion tonnes of recoverable silica. Extracting it via traditional open-pit methods disrupts landscapes, but Sio Silicas approach uses in-situ airlift extraction: drilling vertical wells into the aquifer, injecting compressed air to lift a sand-water slurry to the surface, separating the sand, treating the water, and reinjecting it. This method promises lower surface disturbance but raises questions about aquifer integrity.

The demand surge, fueled by Canadas critical minerals strategy, underscores the economic stakes. Manitoba could supply domestic needs and exports, creating jobs in processing and manufacturing. Yet, balancing extraction with environmental protection remains paramount, especially where aquifers double as drinking water reservoirs for over 120,000 households in the region.

Project History: From Controversy to Revision

The SiMBA project, formerly Vivian Silica Sands, traces back over a decade. Initially proposed by Sio Silica (previously CanWhite Sands), it faced immediate pushback. In 2023, a political scandal erupted when outgoing Progressive Conservative officials attempted to fast-track approval, violating ethics rules and drawing fines. The incoming NDP government rejected the licence in February 2024, citing insufficient data on groundwater risks and subsidence.

Undeterred, Sio Silica submitted a revamped application in October 2025 under the SiMBA banner. Key changes include:

• Reducing initial annual extraction from 1.36 million tonnes to 100,000 tonnes, scaling to 500,000 by year four.
• Starting with 25 wells (in clusters of five), increasing to 167 annually.
• Shrinking the first-four-year footprint by 45% to 350 hectares and lifetime by 66% to 2,764 hectares.
• Adding advanced water filtration, compliance testing, and resident complaint protocols.

Groundwater Concerns at the Heart of the Debate

The Sandilands aquifer, part of the Winnipeg Formation, acts as a natural filter—often likened to the kidneys and liver of the regional ecosystem. Pumping slurry could alter water flow, introduce contaminants during reinjection, or cause voids leading to subsidence. Critics, including residents and groups like Manitoba Eco-Network, warn of irreversible harm to drinking water serving southeastern Manitoba.

Sio Silica counters with four years of baseline monitoring showing no adverse effects. Theyve partnered with Aquatic Life Ltd., a Pinawa-based firm, for real-time data dashboards accessible to communities and regulators. The new U of M collaboration builds on this, promising independent validation through academic rigor.

Hydrogeologist Landon Halloran notes groundwaters invisibility amplifies fears: its vital yet hard to monitor traditionally via costly wells. Non-invasive alternatives like the proposed system could bridge this gap, fostering trust.

Quantum Gravimetry: Revolutionizing Aquifer Monitoring

Central to the research is quantum gravimetry, a technology measuring minute gravity variations to infer groundwater volumes. Gravity accelerates faster over waterless ground (lighter) and slower over saturated areas (heavier). Portable quantum gravimeters detect changes at the microgal level—far surpassing satellite tools like NASAs GRACE-FO, which lack local resolution.

The step-by-step process includes:

1. Deploying sensors across the site for baseline gravity mapping.
2. Monitoring fluctuations tied to extraction cycles.
3. Integrating with models to predict drawdown and recharge.
4. Sharing open data for public verification.

University of Manitobas Pivotal Role in Hydrological Innovation

The University of Manitoba, Canadas oldest and largest in the province, brings world-class expertise through its Faculty of Engineering. Assoc. Prof. Ricardo Mantilla, specializing in hydrology and water resources, leads the study. His work on coupled surface-subsurface flows positions U of M ideally to pioneer this tech locally.

This partnership exemplifies industry-academia synergy, funding PhD research and creating datasets for future studies. It aligns with national priorities in critical minerals while prioritizing sustainability. For aspiring researchers, such collaborations open doors in environmental engineering—explore opportunities at higher-ed research jobs or faculty positions.

Manitobas aquifers demand such innovation; U of Ms involvement ensures peer-reviewed methods, bolstering credibility amid skepticism.

Stakeholder Views: Balancing Economic Promise and Environmental Caution

Supporters highlight jobs, royalties, and green tech supply chains. Devlin envisions SiMBA as national interest, with solar manufacturing tie-ins via RCT Solutions. Long Plain First Nation signed an MOU for review oversight, signaling Indigenous involvement.

Opponents, including Brokenhead Ojibway Nation and residents like Cheryl Sinclair, decry greenwashing and demand independent assessments. Premier Wab Kinew vowed transparency post-scandal. The partnership is praised for openness but scrutinized for industry funding.

Implications for Manitobas Water Management and Beyond

If successful, the monitoring network could model the entire southern Manitoba aquifer, a resource governments might replicate at tens of millions in cost. It sets precedents for in-situ mining nationwide, where silica sands fuel EVs and renewables.

Challenges persist: gravimetry misses quality metrics, requiring hybrid approaches. Broader cases, like Albertas expanding silica leases, echo Manitobas debates. Success here could inform policy, emphasizing real-time data over assumptions.
