Highlights

  • Galan Lithium has officially completed Phase 1 construction at its 100% owned Hombre Muerto West (HMW) Project in Argentina.
  • The project has transitioned into the testing and commissioning phase, with first lithium chloride concentrate targeted for H1 2026.
  • A substantial brine inventory of approximately 10,000 t LCE is ready for processing by late April 2026.
  • Initial production is set at 4,000 tpa LCE, with works to expand capacity to 5,200 tpa LCE commencing shortly.
  • Galan remains one of only two lithium companies in Argentina to benefit from the RIGI investment incentive regime.

Galan Lithium Limited (ASX:GLN) shares surged 10.96% to AUD 0.40 on 1 April 2026. The price increase followed the company's announcement that it has successfully completed Phase 1 construction at its flagship HMW Project. The stock has demonstrated exceptional momentum over the past year, rising 268.18% as the company moves from the development stage toward becoming the next ASX-listed lithium producer.

Transition to Production and Commissioning

The completion of Phase 1 construction marks a definitive shift for Galan. All major processing infrastructure is now installed, including the evaporation ponds and the specialized nanofiltration plant. The company has immediately entered the testing and commissioning phase, performing electrical and mechanical checks to ensure operational readiness.

Following these tests, Galan will begin wet commissioning using raw brine, eventually moving to the pre-concentrated brine currently held in its ponds. With roughly 10,000 t LCE already in inventory, the company is well-positioned to scale processing activities rapidly. First shipments of lithium chloride concentrate are currently forecasted for H2 2026.

Scalable Growth and Strategic Advantages

While Phase 1 will initially produce at an annualized rate of 4,000 tpa LCE, Galan is already looking toward expansion. Construction for a 5,200 tpa LCE rate is slated to begin soon, with a production uplift expected in H1 2027.

Beyond the immediate term, the HMW Project offers significant long-term scale:

  • Phase 2: Fully permitted for 21,000 tpa LCE.
  • Phases 3 & 4: Potential to reach a total capacity of 60,000 tpa LCE.

Managing Director Juan Pablo Vargas de la Vega highlighted that the project's progress was supported by Argentina’s RIGI incentive regime, which provided fiscal stability and facilitated the importation of critical capital equipment.

Low-Cost Positioning in the Lithium Triangle

Located in the heart of the "Lithium Triangle" in Catamarca Province, HMW is distinguished by its high-purity brine and low impurity profile—the lowest reported for any lithium brine resource in Argentina. According to industry benchmarks, the project is profiled to sit in the first quartile of the global industry cost curve once in steady-state production.

What This Means for Investors?

The completion of construction de-risks the HMW Project significantly, moving the narrative from "if" to "when" cash flow begins. With 10,000 tonnes of LCE inventory ready to go and a clear, staged path to 60,000 tpa, Galan is positioning itself as a globally significant, low-cost supplier. Investors are likely reacting to the "imminent producer" status, which often triggers a rerating in the mining sector.
