Goldman Sachs Australia Lithium and Gold Coverage: Bullish on Gold, Bearish on Lithium

Overview

This is a Goldman Sachs 'coverage summary' report for Australian lithium, gold (and niobium miner WA1) coverage stocks, with pricing based on June 5, 2026. It is not a single in-depth logical argument but a systematic comparison of ratings, earnings and cash flow forecasts, valuation multiples, reserves and resources, commodity and exchange rate assumptions for the entire coverage group. The core conclusion is a rating list: Buy NEM, NST, BGL, RMS, WGX, PNR and WA1, Sell PLS, MIN and GGP, with mostly Neutral for the rest. The overall tone presents a structural divergence of 'bullish on gold, bearish on lithium'.

Core views

Rating and Sector Outlook: The Buy list consists almost exclusively of gold stocks (NEM, NST, BGL, RMS, WGX, PNR), plus one niobium company WA1; the Sell list concentrates on lithium-related stocks (PLS, MIN) and GGP. This reflects the report's more optimistic attitude toward the gold sector and more cautious stance on the lithium sector. Lithium Sector: The key signal from the report is 'spot prices significantly above Goldman Sachs' long-term assumptions'. In the commodity price table, Chinese 6% spodumene spot is approximately US$2,550/ton, versus Goldman Sachs' long-term price of only US$1,225 (approximately 52% lower); battery-grade lithium carbonate spot is approximately US$21,978/ton, versus long-term US$15,000 (approximately 32% lower); lithium hydroxide spot is approximately US$20,051/ton, versus long-term US$14,250 (approximately 29% lower). In other words, current market-implied lithium prices are far above levels Goldman Sachs considers sustainable long-term. Meanwhile, lithium sector valuations are relatively expensive, with industry average EV/EBITDA of approximately 11.0x, and PLS as high as approximately 18.8x, hence PLS is given a Sell rating with 12-month target price of A$4.20 (implying approximately 29% downside). The report also shows that if calculated using spot prices, lithium companies' EBITDA would be significantly higher than Goldman Sachs' baseline (e.g., CXO spot approximately 300% above baseline, PLS approximately 180%), indicating these companies' earnings are highly sensitive to lithium prices and current earnings are 'supported' by high prices. Gold Sector: Spot gold price is approximately US$4,480/oz, still above Goldman Sachs' long-term assumption of US$3,800 (approximately 15% higher), combined with relatively lower gold stock valuations (large cap average approximately 6.5x, mid-cap approximately 5.0x EV/EBITDA), and generally higher free cash flow yields (e.g., NEM FY27 free cash flow yield approaching 18%–19%). This forms the basis for most gold stocks receiving Buy ratings. The report also categorizes gold stocks into groups such as large caps, growth mid-caps, high-leverage mid-caps, etc., and compares production growth rates, AISC (All-In Sustaining Costs), hedge ratios, reserve/resource life, etc. Cross-Sectional Comparison and Resource Quality: The report uses numerous charts for peer comparisons, including global lithium project EV/resource and ore grade bubble charts, Australian/Canadian spodumene reserve grade comparisons, and global gold peers (including Barrick, Newmont, Agnico Eagle, Gold Fields, Zijin, etc.) production, EV/ounce, reserve resource life, etc., to judge resource endowments and whether relative valuations are reasonable.

Analysis framework

The main approach is a dual-track comparison of 'base case vs spot case' (GSe Base Case vs Spot). Goldman Sachs first establishes its own long-term commodity price and exchange rate assumptions (base case), then conducts sensitivity calculations using current spot prices, comparing the differences in EBITDA, net profit, free cash flow, and valuation multiples under the two sets of assumptions. The larger the difference, the more sensitive the stock's earnings are to commodity prices, and the more aggressive the price assumptions implied by the current market price. Valuation primarily uses two metrics: P/NAV (Price to Net Asset Value) and EV/EBITDA (Enterprise Value to Earnings Before Interest, Taxes, Depreciation, and Amortization). The report also uses a practical 'reverse' perspective - 'commodity price needed to make NAV = share price', which calculates what long-term lithium/gold price is implied by the current share price, then compares it with Goldman Sachs assumptions and spot prices to determine whether market expectations are too high. The lithium sector also incorporates a supply-demand balance framework: the report lists global lithium demand (EV, ESS energy storage, battery replacement, etc.) and supply (brine, spodumene, lepidolite/clay), inventory days and supply-demand gaps for 2020–2030E to support the judgment of 'long-term price decline'. On the cost side, unit cash costs and AISC (All-In Sustaining Costs) curves are used to see who is more resilient to price declines. Additionally, a four-quadrant chart of 'free cash flow yield vs production growth' is used to position stocks as 'high growth/high cash flow', etc.

Methodology notes

• Valuation methodsP/NAV Resource Property Valuation

  P/NAV: Price to Net Asset Value per share ratio, commonly used for resource stocks

  Discounting future mining cash flows to obtain net asset value per share, then observing whether the stock price is at a premium or discount. A ratio above 1 represents a market premium, below 1 represents a discount. The report uses it to compare lithium and gold stocks to determine which is cheaper, serving as the most common valuation anchor for resource stocks.

• Valuation methodsEV/EBITDA valuation

  EV/EBITDA: Enterprise Value to Earnings Before Interest, Taxes, Depreciation, and Amortization multiple

  Used for comparable valuation between mining companies with different capital structures. The report gives lithium sector average around 11x, gold large caps around 6.5x; the higher the multiple, the more expensive, serving as an important basis for judging PLS as expensive and giving it a Sell rating.

• Event Gaming and Behavioral FinanceExpectation Gap/Expectation Management

  Using 'commodity price needed to make NAV = share price' to reverse-engineer market-implied price expectations

  Reverse calculation: How high do long-term lithium or gold prices need to be to justify the current share price? Comparing this implied price with Goldman Sachs' long-term assumptions and spot prices reveals whether market expectations are too optimistic. This is a practical technique to make 'expectation gaps' explicit.

• Industry/Industrial Analysis FrameworkSupply-demand framework

  Global lithium supply-demand balance sheet (demand, supply, inventory days, gap/surplus)

  Annually listing EV, energy storage, battery replacement demand versus brine, spodumene, lepidolite supply, calculating supply-demand gaps and inventory days. This is the foundation for judging medium to long-term lithium price trends, supporting the report's view that 'long-term lithium prices should be below spot prices'.

• Industry/Industrial Analysis FrameworkCost curve analysis

  Unit cash cost and AISC (including sustaining capital expenditures and stripping) curves

  Comparing the full costs for various mines to extract and sell spodumene/gold. Companies with lower costs are more resilient during price declines. The report uses FY22–FY30E cost trends to determine which stocks can still make money in low-price environments.

• Company Fundamentals and Financial FrameworkFree cash flow analysis

  Free cash flow yield (FCF Yield) and four-quadrant positioning with production growth

  Free cash flow yield measures how much discretionary cash a company can generate at its current market capitalization. The report plots it against future 5-year production growth in four quadrants (high growth/high cash flow, etc.), helping distinguish between 'egg-laying hens' and 'story stocks with growth narratives'.

Impact & implications

According to the report's logic: lithium miners' current earnings and share prices are largely supported by elevated spot prices; once lithium prices return to levels Goldman Sachs considers sustainable, earnings and valuations of high-valuation lithium companies like PLS and MIN will face pressure, which is why they are given Sell ratings; gold stocks are more favored due to high spot gold prices, relatively cheap valuations, and stronger free cash flows. The report also highlights that earnings sensitivity to commodity prices varies significantly across stocks (when calculated using spot prices, some lithium companies' EBITDA is several times higher than baseline), meaning the same price volatility will have different impacts on different companies. The above are all judgments from Goldman Sachs in this report and do not constitute new investment advice.

Risks

• Risk of lithium and gold prices reverting to Goldman Sachs' long-term assumptions (spot prices significantly above long-term assumptions, spodumene approximately 52% higher, gold approximately 15% higher)
• Highly valued companies with earnings highly sensitive to commodity prices (such as PLS, MIN) will face earnings and valuation pressure during price declines

What to watch

• Convergence progress between spodumene/lithium carbonate/lithium hydroxide spot prices and Goldman Sachs' long-term assumptions
• Trend of spot gold prices relative to long-term assumptions and support for gold stock cash flows
• Global lithium supply-demand balance and inventory days changes
