Japan's Sumitomo Metal Mining Co., Ltd. released on July 28 its operating report for the second quarter of fiscal 2026 (ended June 30). The company's gold mines in Japan and Australia produced a total of 12.3 tons of gold, up 18% year-on-year, exceeding the market consensus of 11 tons. The outperformance was primarily attributed to higher ore grades at the Hishikari gold mine and the timely commissioning of the Kalgoorlie smelter expansion project.
Capacity Logic Behind Beating Expectations
Sumitomo Metal disclosed in its earnings report that the fifth vein of the Hishikari gold mine entered the main mining area in Q2, with an average grade of 6.8 g/t, up 15% from the previous quarter. In addition, the Phase II expansion of the Kalgoorlie smelter, a joint project with the Western Australian government, commenced full production in May, boosting daily processing capacity from 1,200 tons to 1,800 tons, directly increasing gold recovery. Sumitomo Metal Managing Director Kenichi Sato said in a conference call: "We expect potential for another 5%-8% increase in output in the second half, and the full-year gold production target of 45 tons remains unchanged."
Following the data release, Sumitomo Metal's stock rose 3.2% in afternoon trading on the Tokyo Stock Exchange, boosting the overall TSE precious metals sector. Japan's Daiwa Securities promptly raised its target price on the company to 6,800 yen, implying 12% upside from the current stock price, maintaining a "Buy" rating.
Profit Recovery Resonance Among Asian Miners
Sumitomo Metal's strong performance is not an isolated case. Korea Zinc announced early this month that its Australian Macquarie gold mine reached design capacity three months ahead of schedule, with Q2 gold output surging 62% year-on-year. Meanwhile, Zijin Mining issued a profit alert on July 25, expecting net profit attributable to shareholders in H1 to grow 35%-40% year-on-year, mainly driven by high gold and copper prices and the ramp-up of the Cukaru Peki copper-gold mine in Serbia.
On the industry level, the World Gold Council's latest July report shows that global gold demand grew 12% year-on-year to 1,250 tons in Q2 2026, with central bank purchases reaching 280 tons, a record high for the period. Gold prices remained in the $2,350-$2,400 per ounce range, up about 20% year-on-year. On the cost side, energy costs in the Pacific Northwest fell 15%, coupled with widespread automation, bringing the average all-in sustaining cost (AISC) of the top 10 gold miners to $1,280 per ounce, down 8% year-on-year.
Brokerage Target Prices Upgraded in Flurry
As results beat expectations, several international investment banks adjusted their ratings on Asian precious metals targets. Goldman Sachs, in a research report released July 28, raised its 12-month target price for Zijin Mining from HK$18.5 to HK$22, citing its "dual drive of copper and gold and leading new project commissioning progress." UBS increased its target price for Sumitomo Metal from 6,500 yen to 7,000 yen, believing the company's "improvement in domestic mine ore grades is sustainable long-term."
Notably, Citibank, in its "Precious Metals Mining Quarterly Outlook" released this week, for the first time upgraded the "Southeast Asian Gold Mining Sector" from "Neutral" to "Overweight," highlighting expansion plans at the Sepon gold mine in Laos (operated by Australia's PanAust) and the Batu Hijau gold mine in Indonesia (a Newmont joint venture). Citibank analysts said: "Infrastructure improvements and mining tax reforms in Southeast Asia are attracting international capital, and gold output growth in the region is expected to lead the world over the next two years."
Portfolio Mining Radar: Which Stocks to Watch?
For investors with precious metals miners in their portfolios, the current phase can focus on three dimensions:
- Output certainty: Prioritize companies with producing mines and clear expansion projects, such as Sumitomo Metal (new vein at Hishikari) and Zijin Mining (Buriticá gold mine Phase II in Colombia)
- Cost advantage: Among companies with AISC below the industry average ($1,300/oz), Indonesia's Merdeka Copper Gold and Japan's Mitsubishi Materials both have AISC below $1,200/oz
- Valuation appeal: Based on 2026 forecast P/E, Korea Zinc (15x) and Australia's Newcrest (14x) trade below the global peer average (18x)
Additionally, Southeast Asian precious metals-related ETFs (e.g., Global X Southeast Asia Gold Miners ETF) saw inflows expand after Sumitomo Metal's earnings release, indicating overall institutional favor for the regional sector.
Risk Reminders and Outlook
Despite positive fundamentals, caution is warranted against gold price correction risks. The implied volatility curve of gold futures at the Chicago Mercantile Exchange (CME) suggests the market has priced in a potential decline in gold prices to $2,200/oz by end-2026. If the Fed unexpectedly raises rates in September, rising real yields could dampen gold prices. Additionally, some Southeast Asian miners face community conflicts and environmental regulatory uncertainties, such as the unresolved export license renewal issue for Freeport's gold mine in Indonesia.
Overall, Sumitomo Metal's Q2 output beat marks an initial signal of profit recovery for Asian precious metals miners. Given the clear trend of industry cost optimization and sustained central bank gold purchases as a structural need, the sector still offers allocation value in the medium term. Investors can use the portfolio mining radar to continuously track quarterly output, cost disclosures, and brokerage rating changes for individual targets to capture structural opportunities.
