Gold prices remain supported, but rising cost pressure puts near-term margin downside risk on Australian gold stocks

Overview

This report updates Goldman Sachs' gold price, copper price, FX, cost, NAV, EPS and 12-month target price assumptions for its Australian gold stock coverage. The core conclusion is that medium- to long-term cash flow and valuations for gold stocks remain supported, but short-term margins may slow due to the recent pullback in the A$ gold price and cost pressure related to diesel, consumables, labor and productivity. Through base, bull and bear gold price scenarios, the report compares P/NAV, 1/3/5-year EV/EBITDA, FCF yield and production growth across stocks to assess relative attractiveness.

Core views

Goldman Sachs believes the short-term risk for the Australian gold sector is that margins fall from recent highs back toward 2H CY25 levels, but medium- to long-term support from gold prices, cash flow and valuations remains in place. Large-cap names should perform more steadily because their asset portfolios are more defensive and cash generation more stable; among mid-caps, RMS, WGX, BGL and PNR stand out more on valuation and growth mix. The report downgrades CMM from Buy to Neutral, mainly because relative share price outperformance and higher spending on growth projects suppress near-term FY27-28E FCF yield; it upgrades EVN from Sell to Neutral, mainly because the sector pullback has widened its valuation discount, while high copper prices improve its defensive margins through by-product credits.

Analysis framework

The report first analyzes the relationship between gold prices and gold-stock margins, then updates near- and medium-term assumptions for gold prices, copper prices and FX. Under US$3,500/oz, base-case and US$5,500/oz gold price scenarios, it compares production growth, FCF yield, P/NAV, EV/EBITDA and implied long-term gold prices across covered stocks. At the individual stock level, it combines NAV, NTM EBITDA, DCF, M&A value, project progress, capex and cost curves to adjust ratings and target prices.

Methodology notes

• Valuation frameworkComparison of P/NAV, EV/EBITDA, FCF yield and implied long-term gold price

  Multi-metric relative valuation

  The report uses P/NAV, 1/3/5-year EV/EBITDA, FCF yield and each stock's implied long-term gold price to compare large-cap and mid-cap gold stocks and determine which names still offer relative valuation appeal under current and forward gold prices.

• Scenario analysisBull and bear gold price scenarios

  US$5,500/oz bull case and US$3,500/oz bear case

  The bull case assumes the spot gold price rebounds by about US$1,000/oz from roughly US$4,500/oz to US$5,500/oz; the bear case assumes gold corrects to US$3,500/oz, and observes the sensitivity of each company's NAV, earnings, FCF and relative valuation.

• Individual stock target price methodologyBlended valuation for CMM target price using NAV, NTM EBITDA and M&A value

  85% fundamental value plus 15% M&A value

  CMM's 12-month target price is derived from 85% fundamental value and 15% M&A value; fundamental value is split equally between NAV and NTM EBITDA, NAV uses a DCF method with a nominal WACC of 9.4%, and M&A value is estimated at 1.3x NAV.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• NEM / NST

  Preferred large-cap gold stocks

  Strengths

  Larger, more defensive asset portfolios, stronger cash generation, balance sheets and capital management capability; NST stands out in production growth and gold price sensitivity, while NEM is more defensive in the bear case on FCF yield and lower sensitivity.

  Weaknesses

  They are still exposed to short-term gold price volatility, renewed cost inflation and near-term operating uncertainty.

  Comparison

  Relative to mid-caps, large-cap names are better able to retain past gains and show defensiveness during pullbacks.

  Risks

  Gold price declines, A$ appreciation, higher-than-expected costs, and production or project execution disruptions.

• RMS

  Preferred mid-cap gold stock for valuation and growth

  Strengths

  Under the base case it is listed as a standout mid-cap for both valuation and growth, and it looks even cheaper on a 5-year forward return basis.

  Weaknesses

  Its appeal depends significantly on delivering medium- to long-term production growth and on the market extending valuation to FY31E.

  Comparison

  The report believes RMS becomes one of the cheaper names in the sector once rolled forward to FY31E.

  Risks

  Ramp-up, capex, cost, gold price and execution timing may fall short of expectations.

• WGX / BGL / PNR

  Buy basket of mid-cap gold stocks

  Strengths

  They offer good risk-reward under the base case; in the bull case PNR and WGX remain attractive on yield and growth, and in the bear case PNR/WGX/BGL still lead mid-caps on FCF yield.

  Weaknesses

  Mid-caps as a group are more vulnerable to gold price volatility and changes in market risk appetite.

  Comparison

  Relative to some peers, all three remain cheaper at current valuations and offer a better growth/FCF mix.

  Risks

  In a gold downside scenario, FCF yield compresses, while cost and project execution risks amplify valuation volatility.

• CMM.AX

  Downgraded from Buy to Neutral

  Strengths

  The Karlawinda expansion, Mt. Gibson and Golden Range provide strong medium-term growth, with production expected to rise from about 125koz FY26E to about 350kozpa FY30E; asset costs are relatively low and funding is relatively strong.

  Weaknesses

  Valuation is fuller after significant outperformance versus peers, Mt. Gibson approvals remain a key milestone, and spending on growth projects reduces FY27-28E near-term FCF yield to about 0-5%.

  Comparison

  Valuation looks closer to the sector once rolled forward to FY29E, but current relative upside is below the peer average.

  Risks

  Delays in Mt. Gibson approvals and construction, capex overruns, cost inflation, operational disruptions, and gold price and AUD/USD volatility.

• EVN.AX

  Upgraded from Sell to Neutral

  Strengths

  After the pullback, valuation no longer trades at a premium, and copper by-product credits from Ernest Henry and Northparkes lift gold margins, making the company more defensive during periods of gold price volatility.

  Weaknesses

  The 12-month target price implies only about 2% upside, and some improvement in deleveraging, cash generation and capital returns has already been more fairly reflected in the valuation.

  Comparison

  Relative to peers, EVN's copper exposure provides wider and more defensive margins, but its upside is well below the peer average of about 33%.

  Risks

  Falling copper or gold prices, capex for growth projects, delays in construction and commissioning, operational disruptions and FX risk.

• GGP

  Sell-rated name

  Strengths

  It may still benefit from overall sector valuation support in a high gold price environment.

  Weaknesses

  In the bear case, the report sees its 5-year FCF yield and production growth as relatively modest, and it appears expensive on both current and forward earnings measures.

  Comparison

  Relative to mid-caps such as PNR/WGX/BGL/RMS, GGP has a weaker valuation and growth mix.

  Risks

  Gold price downside, development costs, near-term cost pressure and market repricing of high valuations.

Key data

• Spot gold price and intra-year volatilitySpot about US$4,500/oz; YTD range about US$4,300-5,600/ozThe report says gold has recently pulled back but remains highly volatile, and the forward curve is still in contango.
• Goldman Sachs long-term gold assumptionLong-term gold price of US$3,800/oz, about A$5,430/oz, used from 2030E onwardGoldman's commodities team remains bullish on gold and expects it to return to about US$5,400/oz by the end of CY26.
• Sector implied long-term gold priceAverage about US$3,225/ozRMS/PNR/WGX/BGL are viewed as implying lower long-term gold prices and therefore offering more attractive relative valuations.
• Cost assumptionFY27 unit cost forecast about 15% above consensusMainly driven by diesel, consumables, labor and productivity, creating near-term margin risk.
• EVN rating and target priceUpgraded to Neutral; 12-month target price A$12.70/sh; about 2% upsideAfter the pullback, the valuation no longer carries a premium, and copper prices help support wider and more defensive margins.
• CMM rating and target priceDowngraded to Neutral; 12-month target price A$16.90/sh; about 18% upsideAfter clearly outperforming peers, valuation is fuller, and FY27-28E near-term FCF yield falls to about 0-5% due to growth project spending.
• CMM production growthFrom about 125koz FY26E to about 350kozpa FY30EMt. Gibson, Golden Range and the Karlawinda expansion drive a 5-year production CAGR of about 25%.
• EVN valuation and cash flowBelow 1x NAV; implied gold price about US$3,650/oz; medium-term FCF yield about 5-10%Copper by-product credits from Ernest Henry and Northparkes improve its defensiveness during gold price volatility.

Impact & implications

The investment implication is that the gold sector no longer simply benefits from rising gold prices; near-term costs and changes in the A$ gold price will determine whether margins give back gains. In portfolios, defensive large-cap names are better able to withstand gold price volatility; among mid-caps, priority should go to RMS, WGX, BGL and PNR, which still offer a combination of valuation discount, FCF yield and production growth. CMM's growth story remains intact but valuation is fuller, while EVN's absolute upside is limited, though the improvement in margin defensiveness from copper prices brings its risk-reward back to neutral.

Risks

• Short-term gold price volatility or a correction from spot levels would compress gold-stock FCF yields and NAV.
• A pullback in the A$ gold price would directly pressure the revenue side for Australian miners.
• Renewed pressure from diesel, consumables, labor, freight and productivity could cause margins to fall back.
• Changes in prices of by-products such as copper and antimony would affect earnings and cost credits for companies such as EVN and CMM.
• AUD/USD exchange rate volatility would affect earnings denominated in Australian dollars.
• Construction, commissioning and ramp-up progress on growth projects may cause deviations in revenue timing, operating costs and capex.
• Operational disruptions, weather, industrial action, technical issues, geopolitics, fiscal matters or heritage protection issues may affect production and guidance.
• Changes in capital returns, M&A or project scope may alter valuation and the investment thesis.

What to watch

• Whether spot gold holds near about US$4,500/oz or moves toward the US$5,500/oz bull case / US$3,500/oz bear case.
• Whether Goldman's commodities team's forecast of about US$5,400/oz by the end of CY26 is realized.
• The impact of changes in the A$ gold price, AUD/USD and the forward curve on Australian gold-stock margins.
• Whether FY27 unit costs remain about 15% above consensus, especially for diesel, consumables, labor and productivity factors.
• CMM's Mt. Gibson permitting, construction, capex and Karlawinda expansion progress.
• Whether EVN's copper price exposure and copper credits from Ernest Henry and Northparkes can continue to support defensive margins.
• Whether PNR/WGX/BGL/RMS maintain leading rankings in FCF yield, EV/EBITDA and P/NAV under different gold price scenarios.
• Whether relative performance continues to diverge between large-cap gold stocks NEM/NST and mid-caps.
