Westgold Resources Greenlights A$145m Higginsville Expansion: Is WGX a Buy as Gold Stays Strong?

Westgold Expansion Boosts Growth Case for WGX

Westgold Resources (ASX: WGX) rose just 3.2% to A$6.45 on Tuesday after its board approved a Final Investment Decision to expand its Higginsville Processing Hub in Western Australia at a cost of A$145 million. For a decision of this scale, the reaction was quiet. With gold prices hovering near record highs, we believe the market may be underestimating what this expansion could mean for Westgold’s free cash flow trajectory from mid-FY28 onwards.

Westgold Bets Big on Higginsville as Gold Prices Provide Tailwind

Higginsville, located in Western Australia’s Southern Goldfields, is one of Westgold’s key processing assets. The approved expansion will lift the hub’s throughput capacity from 1.6 million tonnes per annum to 2.6 million tonnes per annum, a 62.5% increase. That translates to roughly 60,000 additional ounces of gold production per year from the Southern Goldfields once the expanded plant reaches full capacity.

The timing looks strategic. Gold prices remain elevated globally, and for Australian producers, the local gold price has been even more supportive given a softer Australian dollar. Locking in a major production growth decision now means Westgold could be harvesting significantly more ounces when commissioning begins from mid-FY28, assuming prices hold or improve.

What makes this expansion particularly appealing is the cost angle. The upgrade is expected to cut processing costs by 24% to A$34 per tonne and reduce the Southern Goldfields midpoint AISC by approximately A$142 per ounce. For a company that reported an all-in sustaining cost of A$2,871 per ounce in H1 FY26, bringing unit costs down is not a nice-to-have; it is essential for protecting margins if gold prices pull back from current highs.

What a A$145m Capex Commitment Means for Westgold’s Financials

The first question investors rightly ask is: Can Westgold afford this without stretching the balance sheet? Based on the numbers, the answer appears to be yes. Westgold reported an underlying treasury of A$550 million in H1 FY26, and as of June 2025, the company held total available liquidity of A$614 million, including a A$250 million undrawn credit facility. Against that backdrop, a A$145 million commitment spread across FY27 and FY28 looks manageable.

Construction is scheduled to begin in FY27, with commissioning and production uplift expected from mid-FY28. That means there is no immediate earnings impact. Investors buying today are essentially pricing in a future production step-up and cost improvement that will not show up in results for another two years.
The company has also future-proofed the expansion by selecting equipment capable of supporting a further scale-up to 4 million tonnes per annum if needed down the track. That optionality is an underappreciated detail.

The Investor’s Takeaway

Westgold is not cheap at a market cap of approximately A$6.1 billion, and current AISC above A$2,800 per ounce (including purchased ore) leaves limited room for error if gold retreats sharply. The two-year wait for production benefits from this expansion also means investors need patience.

That said, we believe WGX suits growth-oriented investors who want leveraged exposure to gold with a credible long-term cost reduction story behind it. The strong balance sheet removes near-term funding risk, and the Southern Goldfields expansion adds a concrete production catalyst to the thesis.

For investors already holding WGX, this approval strengthens the case to stay. For those on the sidelines, waiting for a cleaner entry point below A$6.00 would improve the risk-reward balance considerably.
