Key Positives From The Results
Operating income in the Metals segment surged +157.6% YoY to JPY 2,019M, capturing tailwinds from rising copper prices (431.75→604.38¢/lb) and yen depreciation (144.59→159.49 JPY/USD). Consolidated operating income of JPY 5,088M represents 36.3% progress against the full-year plan of JPY 14,000M—an above-expectation start.
- Metals (Mining):Copper prices rose +40.0%, and lower production costs absorbed the volume decline, driving earnings growth. The Atacama mine's earnings power became evident
- Metals (Smelting):Earnings increased on favorable FX effects, improved by-product revenue, and higher sales premiums
- Gross Profit Margin:Declined to 20.2% (▲1.2pt YoY), though gross profit rose to JPY 11,617M (+17.3% YoY)
- Cross-Shareholding Sales:Gains of JPY 2,759M on disposal of policy-held shares contributed to net income of JPY 4,782M (+45.0% YoY)
- Capital Efficiency:Treasury share buybacks advanced; treasury stock increased by JPY 3,012M versus FY-end
Key Concerns From The Results
Recurring profit came in at JPY 4,470M (▲0.6% YoY), with the operating income uplift offset at the non-operating level. Equity-method investment losses of JPY 450M, FX losses of JPY 322M, and derivative valuation losses of JPY 290M weighed on results.
- Equity-Method Affiliates:Investment income of JPY 263M swung to losses of JPY 450M (primarily Hibi Joint Smelting), warranting close attention to the changing smelting environment
- Arqueros Mine:Heavy rainfall in July temporarily halted construction work, posing schedule-delay risk to the targeted start of operations in Jul–Sep 2026
- Limestone Volume:Sales declined ▲9.1% from 5,722kt to 5,199kt, with volume down across all end-uses—steel, cement, and aggregates—although the company assumes a recovery toward year-end
- Machinery & Environment:Operating income fell ▲14.4% from JPY 489M to JPY 419M due to surging raw material costs for the water treatment agent Politetsu
- Long-Term Debt:Increased +18.7% from JPY 44,719M to JPY 53,069M, reflecting debt financing for the Arqueros mine and other investments
Focus Areas / Items To Monitor Going Forward
- Timeline for recovery from the Arqueros mine (80% interest; planned annual output of 15kt copper equivalent) heavy-rain damage and its impact on the operations start date. Consistency with cost outlays embedded in full-year guidance is the key focus
- Q1 copper price of 604.38¢/lb is ~10% above the full-year assumption of 550.00¢/lb. Upside potential to full-year operating income depends on market conditions from Q2 onward; the gap versus the FX assumption of JPY 155/USD also needs monitoring
- Progress and investment scale of the Oracle Ridge copper exploration project in the US and other overseas resource development pipelines
- Quantitative impact of the Arqueros mine operational delay on full-year guidance and whether revisions are necessary
- Insurance coverage for the Arqueros mine flood damage and estimated additional costs
- Root cause of the deterioration in equity-method investment losses (Hibi Joint Smelting) and outlook for TC/RC conditions
- Breakdown of the JPY 290M derivative valuation loss and hedging policy going forward
- Drivers behind the volume decline in limestone by end-use and expected timing of volume recovery
- Anticipated timeline for the development decision on the Puquios copper mine project
- Progress on passing through raw material cost increases for the water treatment agent Politetsu, and expected benefits from the Sodegaura Chemical Center coming online
- Policy for further disposal of policy-held shares and targets for reducing the remaining balance
- Future policy on treasury share buybacks

Performance By Business Segment
The Metals segment recorded the largest increase in both revenue and operating income among all segments, driven by copper price and FX tailwinds, and led consolidated results. The Mineral Resources segment saw higher revenue on price increases, but limestone volume declines kept profit flat. The Machinery & Environment segment saw higher environmental products revenue offset by raw material cost inflation, resulting in lower earnings. Real Estate and Renewable Energy remained stable.
Segment Performance Table
| Segment | Revenue | YoY | Operating Income | YoY | Margin |
|---|---|---|---|---|---|
| Mineral Resources | JPY 17,958M | +4.7% | JPY 2,478M | ▲0.3% | 13.8% |
| Metals | JPY 34,737M | +41.8% | JPY 2,019M | +157.6% | 5.8% |
| Machinery & Environment | JPY 4,236M | +10.4% | JPY 419M | ▲14.3% | 9.9% |
| Real Estate | JPY 687M | ▲5.5% | JPY 445M | +3.9% | 64.8% |
| Renewable Energy | JPY 478M | ▲1.3% | JPY 183M | ▲5.9% | 38.3% |
- Metals (Mining / Copper Concentrate): Copper prices rising from 431.75 to 604.38¢/lb (+40.0%) was the primary revenue driver. Volume fell ▲25.5% from 10,067t to 7,497t due to plant trouble, but price gains and lower production costs drove earnings higher
- Metals (Smelting / Electrolytic Copper): Higher domestic selling prices lifted revenue from JPY 16,648M to JPY 23,787M (+42.9%). FX effects, improved by-product revenue, and higher sales premiums contributed to earnings growth
- Metals (Others): Higher volumes and prices for electrolytic gold and silver doubled revenue from JPY 2,882M to JPY 5,930M (+105.8%)
- Mineral Resources (Limestone): Sales volume fell from 5,722kt to 5,199kt (▲9.1%)—steel-use ▲10.2%, cement-use ▲7.5%, aggregates-use ▲9.3%—declining across all end-uses. Revenue decreased from JPY 9,380M to JPY 8,949M (▲4.6%)
- Machinery & Environment (Operating Income): Surging raw material costs for the water treatment agent dragged operating income from JPY 489M to JPY 419M (▲14.3%)
Progress Versus Full-Year Guidance
Q1 operating income progress of 36.3% represents a strong start, particularly given that full-year guidance calls for a decline (▲25.6% YoY). However, the company expects full-year results to track guidance, factoring in the ramp-up of Arqueros mine development costs from Q2 onward and the absence of the prior-year Q2 real estate disposal gain. With Q1 copper prices of 604.38¢/lb exceeding the full-year assumption of 550.00¢/lb, there is potential upside depending on market conditions.
| Item | Value (Q1 Cumulative) | Full-Year Forecast | Progress Rate |
|---|---|---|---|
| Revenue | JPY 57,406M | JPY 232,500M | 24.7% |
| Operating Income | JPY 5,088M | JPY 14,000M | 36.3% |
| Recurring Profit | JPY 4,470M | JPY 11,500M | 38.9% |
| Net Income | JPY 4,782M | JPY 12,000M | 39.9% |
- Limestone volumes declined in Q1 due to customer-side issues; the company assumes volume recovery toward year-end
- From Q2 onward, Arqueros mine development cost outlays will intensify, resulting in an expected quarterly skew (Q1-heavy / Q2–Q4 lower) in operating income
Changes To Guidance
No change from the full-year guidance published on May 13, 2026. Revenue of JPY 232,500M (+10.9% YoY), operating income of JPY 14,000M (▲25.6% YoY), and net income of JPY 12,000M (▲14.5% YoY) are maintained. The impact of the Arqueros mine heavy rainfall is under assessment; potential for future revisions should be noted.
Commentary On Shareholder Returns
The FY2027/3 annual dividend forecast remains unchanged at JPY 62.00/share (interim JPY 31.00, year-end JPY 31.00). The company targets a consolidated payout ratio of ~40%, with a fixed dividend floor of JPY 34.00/share, applying whichever is higher. Treasury share buybacks progressed during Q1, with shares held increasing from 1,317,977 to 2,522,877 (+1,204,900 shares).
Financial Position
Long-term borrowings rose by JPY 8,349M, and interest-bearing debt is on an upward trajectory, but the financial foundation remains solid with shareholders' equity of JPY 158,111M. The Arqueros mine development investment is the primary driver of funding needs.
