Two Gold Miners, Same Problem: Priced for Perfect Gold
Evolution Mining and Northern Star are both competent gold miners trading at extreme premiums. The entire valuation gap comes down to a single disagreement: gold price regime.
Evolution Mining and Northern Star Resources are the two largest gold producers on the ASX, and both are trading at extreme premiums to our fair values. EVN at A$16.28 sits 65% above our A$5.74 fair value. NST at A$29.30 sits 60% above our A$11.62. The quality gap between them (EVN at 6.1/10 vs NST at 5.4/10) is real but secondary. The primary driver of both valuations is the same: the market prices gold at permanently elevated levels, and our analysis does not.
This is not a comparison about which gold miner is "better." It is about whether either offers acceptable risk-reward at current prices, and what gold price the market is embedding in each share price to arrive at these numbers.
The Comparison

Gold spot is US$5,110/oz (A$~7,100), near all-time highs. Both companies are generating record or near-record margins. The question is whether those margins persist.
Where EVN Wins
Cost position. EVN's group AISC of A$1,493/oz is nearly half NST's A$2,720/oz. The gap is structural, not cyclical: EVN's Ernest Henry and Northparkes mines produce significant copper by-product credits that push AISC negative at those operations. At Ernest Henry, the AISC is effectively negative A$3,468/oz because copper revenue offsets gold mining costs entirely. NST has no equivalent by-product offset. In a gold downturn, EVN's cost buffer is roughly A$1,200/oz wider than NST's.
Copper diversification. EVN derives approximately 20% of revenue from copper, and this share is growing. The newly approved E22 block cave at Northparkes (A$545M, 28% IRR at A$4,000 gold) extends copper production by 9+ years and deepens the cost advantage. NST is a pure gold play with no meaningful by-product exposure, leaving it entirely dependent on gold price direction.
Balance sheet flexibility. Both balance sheets are in good shape, but EVN's trajectory is stronger. Gearing has fallen from 25% to 6% in 18 months. Net debt of A$362M against A$1.5B liquidity funds the entire A$780M growth pipeline without dilution. NST has net cash of A$293M but is burning A$720M per half on capex, with A$3.3B in annual capital expenditure and negative underlying free cash flow.
Execution track record. EVN's Mungari expansion was delivered 15% under budget and 9 months early. AISC guidance has been consistently met or beaten. NST had its FY26 production guidance downgraded twice in January 2026 (from 1,700-1,850koz to 1,600-1,700koz) with simultaneous operational failures across all three production centres. EVN's management credibility edge is narrow on score (7.6 vs 7.5) but wider in recent evidence.
Where NST Wins
Scale. NST produces more than double EVN's gold output: 1.63Moz in FY25 versus 750koz. It is the largest pure-play gold producer on the ASX and a top-10 producer globally. Scale provides greater leverage to gold price moves (each A$100/oz equals ~A$240M EBITDA for NST versus ~A$75M for EVN) and more relevance for institutional mandates requiring minimum market capitalisation or index inclusion.
Reserve base. NST's 30Moz+ resource base, anchored by KCGM's 100-year mine history, dwarfs EVN's 15.5Moz. The Hemi development project adds ~10Moz of undeveloped resource in a Tier-1 jurisdiction. Reserve depth provides longer production visibility, though it also means more capital required to convert resources into cash flow.
KCGM expansion catalyst. The mill expansion to 27Mtpa is approximately 85% complete and targeted for early FY27 commissioning. This adds 200-300koz of production at declining marginal cost, because fixed costs are spread over higher throughput. If it delivers, NST's cost curve position moves from 3rd quartile toward 2nd quartile globally, and annual FCF inflects sharply positive as growth capex drops from A$1.4B to ~A$200M.
H1 FY26 results momentum. NST's just-released half-year showed revenue of A$3.41B (+19%), EBITDA of A$1.88B (+34%), and NPAT of A$760M. The share price rose 3.9% on the day. While driven primarily by gold price rather than operational improvement, the top-line growth demonstrates the production base's earnings leverage in a favourable gold environment.
The Gold Price Question
The analytical tension in both cases is identical: our model assigns roughly 35% probability to gold price mean-reversion over 1-3 years, while the market prices near-zero reversion probability into both stocks.
The structural case for elevated gold has credible support. Central bank buying has exceeded 1,000 tonnes per year for three consecutive years. De-dollarisation trends, geopolitical fragmentation, and negative real rates in several major economies provide demand-side anchors that differ from previous gold cycles. Gold at US$5,110/oz is not baseless.
The cyclical case is equally grounded. Gold surged 41% from 2010 to 2011 before declining 45% over the next two years. Speculative positioning is elevated. The marginal buyer at current prices is paying for a permanent regime shift in global monetary architecture, which is a bet that may prove correct but has a historical base rate below 50%.
Our analysis does not pick a side. It probability-weights three gold scenarios for each company and lets the maths determine fair value. The table below shows how each company's valuation changes under different gold price assumptions.
EVN Scenario Valuations
| Scenario | Gold Price (A$/oz) | Probability | Fair Value/Share |
|---|---|---|---|
| Base Case | A$5,500 | 65% | A$6.87 |
| Bear Case | A$4,500 | 25% | A$4.12 |
| Severe Case | A$3,800 | 10% | A$2.45 |
| Probability-Weighted | 100% | A$5.74 |
NST Scenario Valuations
| Scenario | Gold Price (A$/oz) | Probability | Fair Value/Share |
|---|---|---|---|
| Bull Case | A$4,500+ | 15% | A$18.24 |
| Base Case | A$3,550 | 50% | A$11.89 |
| Bear Case | A$3,300 | 25% | A$6.42 |
| Severe Case | A$2,800 | 10% | A$3.90 |
| Probability-Weighted | 100% | A$11.62 |
Even in EVN's base case (A$5,500 gold, no recession, continued execution), the stock is worth A$6.87, which is 58% below the current share price. For NST, the bull case (gold structurally above A$4,500, KCGM and Hemi both deliver) produces A$18.24, still 38% below the current price. The market is pricing both stocks beyond even the optimistic end of our scenario range.
What Gold Price Is Embedded in the Share Price?
This is where the maths gets instructive.
EVN at A$16.28 requires sustained gold above A$7,500/oz in perpetuity with zero probability of mean-reversion. At that price, EVN generates 55%+ EBITDA margins and A$1,800-2,000M annual FCF. The market is pricing the current spot environment (gold ~A$7,100) as permanent, and then adding a premium.
NST at A$29.30 requires gold permanently above A$4,500/oz, which our model assigns 50% probability. But the market also prices NST at 11.3x EV/EBITDA against an 8.0x peer median, despite below-average quality (5.4 vs 6.2/10 peer average). To justify both the gold assumption and the multiple premium, NST needs KCGM to deliver on time, Hemi to proceed to FID, and gold to cooperate, all simultaneously.
The implied gold prices suggest both stocks are priced for a world where the gold bull market is permanent and operational risks do not exist. Our analysis respects the structural gold thesis (we assign 45-50% probability to it) but cannot endorse the zero-reversion assumption embedded in current prices.
Bottom Line
EVN is the better business. Higher quality score (6.1 vs 5.4), lower costs (AISC A$1,493 vs A$2,720), copper diversification, stronger balance sheet trajectory, and a cleaner execution record. In a gold downturn, EVN's copper credits provide a buffer that NST simply does not have.
NST has greater scale, a longer reserve life, and a clearer production growth catalyst in KCGM. If gold stays above A$4,500 for a decade, NST's asset base is worth more in absolute terms. But that is a large conditional.
At current prices, neither is a buy. Both require gold to remain at or near record levels indefinitely while delivering flawless operational execution. Our analysis suggests expected returns from current entry points are significantly negative for both stocks, with the entire valuation gap attributable to a gold price regime disagreement between our probability-weighted approach and the market's implicit assumption of permanence.
For investors who have a high-conviction view that gold is structurally repriced (above A$4,500 permanently), NST offers more leverage to that thesis through pure gold exposure and production growth. For investors who want gold exposure with downside protection, EVN's copper credits and lower cost base provide a wider margin of safety. For investors who assign any meaningful probability to gold mean-reversion, the risk-reward at current prices is unfavourable for both.
