# LUCA MINING ANNOUNCES ACQUISITION OF THE COZAMIN MINE, CREATING A LEADING POLYMETALLIC PRODUCER Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/luca-mining-announces-acquisition-of-the-cozamin-mine-creating-a-leading-polymet--fc4b68ab-34d3-437d-b097-e1edecc66257 Original source: https://orestocks.com/company/LUCA.V/press-releases/6904905135194279 Publisher: orestocks Original announcement: 2026-09-21T09:50:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-21T11:05:40.976Z Atlas analysis updated: 2026-09-21T11:05:40.976Z - Company: Luca Mining Corp. - Ticker: LUCA.V - Exchange: Unavailable - Region: Zacatecas, Mexico - Primary commodity: Copper - Secondary commodities: Silver, Zinc, Lead, Gold - Document categories: Resource update, Agreement transaction - Extracted: 2026-09-21 11:05:41 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Luca Mining Corp. has entered into a definitive agreement to acquire 100% of the Cozamin Mine in Zacatecas, Mexico, from Capstone Copper Corp. for $290 million upfront and up to $95 million in deferred/contingent consideration. The transaction is expected to more than double Luca's 2027 production and is supported by a $300 million financing package including private placements and a senior secured facility. Reasoning: The acquisition of the Cozamin mine is a transformational M&A event that significantly scales Luca's production and cash flow profile. - Positive factor: Transformational acquisition doubling near-term production - Positive factor: Highly accretive to operating cash flow per share - Positive factor: Strategic expansion into productive Mexican mining region - Positive factor: Strong financing package with strategic equity partners - Negative factor: Reliance on historical estimates requiring verification - Negative factor: Contingent consideration and copper-price linked payments Facts used in scoring: 8 ## Classification and evidence **Historical Estimate Only** Polarity: negative Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling. Why it applies: The Cozamin resource and reserve estimates are explicitly stated as historical \(2025\) and prepared by Capstone, not Luca. Evidence · text > The Project's mineral resource and reserve estimates disclosed in Figure 2 and Figure 3 below are historical \(2025\) in nature and are being treated by Luca as historical estimates under NI 43-101. **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: The technical information was reviewed and approved by Mr. Paul D. Gray, a Qualified Person. Evidence · text > The technical information contained in this news release has been reviewed and approved by Mr. Paul D. Gray, P.Geo., Vice President Exploration at Luca Mining. Mr. Gray is a Qualified Person for the Company as defined by NI 43-101. ## Extracted facts Stored fact records: 8.
