# Rock Tech Advances Georgia Lake Lithium Project, Identifies Potential Pathway to Reduce Processing CAPEX by Up to 50 per cent Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/rock-tech-advances-georgia-lake-lithium-project-identifies-potential-pathway-to--9431e332-2666-4639-8147-f7f1dffc4ebc Original source: https://money.tmx.com/en/quote/RCK/news/8675066543677104/rock-tech-advances-georgia-lake-lithium-project-identifies-potential-pathway-to- Publisher: tmx Original announcement: 2026-05-19T13:45:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Rock Tech Lithium Inc. - Ticker: RCK - Exchange: TSX - Region: Northern Ontario - Primary commodity: Lithium - Secondary commodities: None reported - Document categories: Metallurgy, Economic study - Extracted: 2026-09-16 18:41:55 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Rock Tech Lithium has completed pilot-scale ore-sorting test work at its Georgia Lake Lithium Project in Ontario. The program demonstrated that ore sorting can remove 25-45% of waste and improve ore quality by 1.4x to 1.8x, potentially reducing downstream crushing and concentrator capital costs by up to 50%. Reasoning: The announcement reports successful pilot-scale ore-sorting test work that suggests significant potential for CAPEX reduction and grade improvement, though these are not yet confirmed in a formal study. - Positive factor: Ore-sorting test work demonstrated significant waste removal \(25-45%\) - Positive factor: Potential to reduce crushing and concentrator CAPEX by up to 50% - Positive factor: Improved ore quality factor of 1.4x to 1.8x - Positive factor: Government funding \(CMIF\) de-risks early-stage innovation - Negative factor: Results are preliminary and based on limited-scale pilot testing - Negative factor: Economic benefits are conceptual and require further engineering/DFS validation Facts used in scoring: 2 ## Classification and evidence **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Test work was conducted using pilot-scale equipment on limited sample sets, not full-scale production. Evidence · text > Testing was completed under controlled conditions at both ore sorting test facilities using pilot-scale equipment. **PEA-Supporting** Polarity: neutral Story-specific tag Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: The results are intended to support future technical studies, including a potential Definitive Feasibility Study. Evidence · text > The results provide a foundation to restart key Georgia Lake development activities... that support a future Definitive Feasibility Study. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("concentrator"\) **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 1.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
