AABB’s state-of-the-art Etzatlán Processing Plant, located in Jalisco, Mexico, forms the cornerstone of the company’s ambition to scale gold and silver production, enhance extraction efficiency, and drive shareholder value. From inception to full-scale operations, the facility has been purpose-built with modular scalability, advanced automation, and integrated testing to deliver robust performance, cost control, and transparency.
1. Site Acquisition & Infrastructure Establishment
In December 2022, AABB completed the purchase of the land parcel for the mill site in Etzatlán to support its long-term ore-stockpile processing strategy. AZoMining+2TradingView+2
The property includes key water rights and logistical access to the nearby ore stockpile (approximately 5.8 miles away) in Las Jiménez. AZoMining
Early civil works established foundations, access roads, utilities, power, tailings containment, and slurry water circuits to prepare for major processing equipment installation.
AABB has sourced major processing components from Mecru Heavy Industry Technology (Zhengzhou, China). GlobeNewswire+2GlobeNewswire+2
To date, 6 containers of key equipment (centrifugal concentrators, press filters, hydraulic thickening systems, slurry pumps, thickener tank bridges) have arrived and are being integrated into the facility. Stock Titan+3GlobeNewswire+3GlobeNewswire+3
Remaining deliveries of spare parts and critical ancillary systems (e.g. ball mill liners, filters, bushings) are expected in upcoming weeks. Stock Titan+2GlobeNewswire+2
Starting in March 2025, AABB technical teams initiated rotating tests of key systems (crushing, milling, flotation, pumping, thickening) to validate performance, flow balances, and reliability. TradingView+1
By April 2025, the plant entered final commissioning stages in advance of its grand opening and ribbon-cutting ceremony. TradingView+2Mining Stock Education+2
All subsystems are being stress-tested in sequence to ensure smooth integration under full-load operation.
4. Phase 1 Production — Flotation & Initial Throughput
The target throughput ramp timeline: • First 3 months: ~ 350 tons per day • Full rate thereafter: up to 500 tons per day Mining Stock Education+2GlobeNewswire+2
AABB projects an average production cost of approximately USD 56.75 per ton for this initial flotation line. Mining Stock Education+1
To further boost metal recovery, a cyanidation (leaching) circuit is slated for commissioning in September 2025. Mining Stock Education+2MINING.COM+2
The ramp schedule for the cyanidation line: • Months 1–4: ~ 200 tpd • Gradually escalating to 500 tpd Mining Stock Education+1
Because cyanidation typically yields higher recoveries for precious metals, net revenue projections under this circuit are robust: • First 4 months: USD 2,554,367 MINING.COM • First 12 months: USD 15,326,203 MINING.COM
The Phase 2 line is currently being integrated into the plant infrastructure, with the new processing equipment gradually installed and tested. GlobeNewswire+2GlobeNewswire+2
6. Ongoing Optimization, Scaling & Quality Control
An on-site metallurgical laboratory and testing program enables real-time assay, batch tuning, reagent optimization, and throughput calibration, which together raise yield, reduce losses, and lower operating risk. GlobeNewswire+3Mining Stock Education+3GlobeNewswire+3
Continual process data analytics, sensor feedback control, and remote monitoring ensure process stability, fast troubleshooting, and lean operations.
7. Shareholder Engagement & Transparency
Due to high demand, AABB plans to expand tour capacity in future events, enabling broader investor access to the facility. MINING.COM
In May 2025, AABB hosted a week-long shareholder tour of both the La Paz Mine and the Etzatlán facility. Participants were flown by helicopter from Guadalajara to gain first-hand exposure to AABB’s operations, engineering systems, and daily production workflows. MINING.COM+1
As a token of appreciation, the company gifted a commemorative silver coin, manufactured from plant-processed silver, to the largest shareholder on each tour day. MINING.COM
Notably, one coin recipient holds over 5 % of AABB’s outstanding shares; the company will reflect this stake in its upcoming quarterly disclosures. MINING.COM
