Executive Summary

Sierra Madre Gold and Silver Ltd. has officially closed the acquisition of the Del Toro Silver Mine from First Majestic Silver Corp.
Transaction consideration totals up to US$60M, structured as US$20M cash at closing, US$10M at 18 months, US$10M at 48 months (triggered by ≥100 Moz AgEq resource), and US$10M at 60 months (triggered by ≥4,000 tpd commercial production).
Concurrently, the company closed a brokered private placement of subscription receipts for gross proceeds of approximately $57.5M CAD at $1.30 CAD per receipt to fund the acquisition and near-term Del Toro exploration/development.
First Majestic received 10,870,000 shares at a deemed price of $1.30 CAD, bringing its post-closing ownership to ~24.77% (non-diluted). Shares are subject to a 4-month hold period followed by quarterly releases.
The deal was previously announced in December 2025, approved by shareholders in April 2026, and cleared Mexican antitrust (COFECE) in May 2026.

Material Impact

This is a Routine - Positive event. The acquisition was fully funded, shareholder-approved, and regulatory-cleared months ago. The market has already priced in the Del Toro asset, as evidenced by the stock's run to $3.09 in January 2026 followed by a steady pullback to current levels.
The closing removes execution risk on the M&A front but shifts the burden to operational execution: restarting a care-and-maintenance asset, validating historical resources, and controlling cash costs.
The $57.5M CAD financing is already in escrow; its release to Sierra Madre is now certain, strengthening the balance sheet for the upcoming restart phase.
