ACG Metals beats guidance as copper transition nears: a detailed 2025 wrap-up and what 2026 could mean

ACG Metals Limited has ended 2025 with a clear message to investors: operations are running strongly, costs are being managed tightly, and the company’s long-planned move into copper production is approaching fast. In its FY and Q4 2025 operations update, ACG reported production above guidance, meaningful improvements in unit cash costs, and solid progress on the Gediktepe Sulphide Expansion Project, which is expected to bring the company into commercial copper production by the end of the first half of 2026.

This article rewrites and expands the key points of the news in plain English, with extra context so readers can understand why the update matters, what has changed versus last year, and what to watch next.

Quick highlights (what investors usually read first)

• 2025 production exceeded guidance: 39.2 koz AuEq produced, which was about 3% above the top end of guidance.
• Sales were also strong: 39.5 koz AuEq sold during 2025.
• Cash-cost performance improved: C1 cash costs fell to about US$499/oz AuEq (an 18% reduction year-on-year in the company’s summary).
• 2026 guidance shifts the story toward copper: ACG guided to 20–22 ktpa CuEq production in 2026, with expected AISC around US$2.40–US$2.60/lb CuEq.
• Major project remains on time and on budget: the sulphide expansion at Gediktepe is expected to reach commercial production by the end of H1 2026.
• Net debt reported at year-end: about US$65 million as of 31 December 2025.

Who is ACG Metals, and why Gediktepe matters so much

ACG Metals is listed in London and has been positioning itself as a growth-focused mining company with a plan to become a meaningful copper producer over time. The company’s near-term operational story is closely tied to the Gediktepe mine in Türkiye, which has produced gold and silver from oxide ore while the company builds a much larger sulphide operation designed to produce copper (and potentially other payable metals depending on the final flowsheet and concentrate terms).

For investors, Gediktepe is important for two reasons:

1. It funds the transition: oxide production can generate cash flow while the company completes the sulphide expansion.
2. It changes the company’s identity: once the sulphide plant is running, ACG expects to move from being seen mainly as a precious-metals producer toward being valued more like a copper producer.

2025 production: beating guidance is more than a headline

ACG’s announcement that it produced 39.2 thousand ounces of gold equivalent (AuEq) in 2025 is a key operational milestone. Beating guidance is often a sign of operational control—especially when it happens alongside lower costs—because it suggests the mine plan, plant performance, and day-to-day execution are working together.

It’s also worth noting that ACG described 2025 as the first full year of Gediktepe under its ownership. First-year ownership transitions can be tricky in mining: new teams may revise plans, re-baseline costs, adjust maintenance strategies, and update supply chains. A strong operational finish can help reduce market doubt about whether a new owner can run the asset efficiently.

What “AuEq” means (in simple terms)

AuEq stands for “gold equivalent.” It’s a way to combine gold and silver (and sometimes other metals) into one number based on assumed prices and recoveries. It is helpful for quick comparisons, but readers should remember that real-world revenue depends on actual metal prices, payable terms, recoveries, and timing of sales.

Costs: why the C1 cash-cost drop matters, and why AISC moved the other way

In mining updates, costs are often as important as production, because high costs can shrink margins even when output is strong. ACG said operational efficiency and cost controls drove an 18% reduction in C1 cash costs to about US$499/oz AuEq.

C1 cash costs are commonly used to describe direct site cash costs—think mining, processing, site G&A, and other operating costs. When C1 improves, it often indicates better productivity, tighter procurement, more stable operations, or all of the above.

At the same time, ACG reported AISC (all-in sustaining costs) increased year-on-year to about US$1,244/oz AuEq from US$1,139/oz AuEq. The company attributed the rise mainly to higher gold and silver prices, which increased royalty payments. That may sound odd at first—higher prices usually feel “good”—but royalties can be linked to revenue or price bands, which means the cost line can rise when commodity prices climb.

Quick glossary: C1 vs AISC

• C1 cash costs: a narrower view of operating cash costs at the site level.
• AISC: a broader measure that can include sustaining capital, royalties, and other items intended to represent the full cost of staying in business at the current scale.

Safety: a detail that often predicts performance

ACG reported a Lost Time Injury Frequency (LTIF) of 0.66 for the year and noted 1.6 million man-hours worked LTI-free. Safety may feel like a separate topic from output and cost, but over long periods, strong safety culture often supports strong operations. Fewer incidents can mean fewer stoppages, better workforce stability, and better contractor management—especially important when a construction workforce grows during major project build-outs.

The company also highlighted a focus on improving contractor safety as the construction workforce peaks in the first half of 2026. That point matters because project execution risk often increases when the number of contractors rises quickly.

The sulphide expansion: the engine behind the “copper transition”

The central strategic point in the update is the Gediktepe Sulphide Expansion Project. ACG said the project advanced significantly during 2025 and remains on time and on budget, targeting commercial production by the end of H1 2026. If achieved, that timeline would mark the moment ACG becomes a copper producer in a meaningful operational sense.

When markets hear “on time and on budget,” they often react positively because construction delays and cost overruns are among the most common value destroyers in mining. A project can be technically excellent, but if it arrives late or much more expensive than planned, returns can shrink fast.

Why timing matters in 2026

ACG’s timing aims to align with a period when copper is widely viewed as a strategic metal for electrification, grid upgrades, and industrial demand. Even though copper prices move up and down, the long-run demand narrative is often supportive. For ACG, entering copper production with a clear plan and stable funding approach could help investors re-rate the company from a small producer into a growth story.

2026 guidance: from ounces to copper-equivalent tonnes

Another major shift is the way ACG is now guiding the market. For 2026, the company provided guidance of 20–22 thousand tonnes per annum (ktpa) copper equivalent (CuEq), including 17.5 koz AuEq of oxide production that has been stacked and is under leach.

This is important because it signals that 2026 is a transition year: oxide production continues, but the company is preparing the market for a different production mix as sulphide operations ramp up.

ACG also guided to AISC of approximately US$2.40–US$2.60 per pound CuEq for 2026. Investors will watch closely whether early copper production meets cost expectations, because new circuits can take time to stabilize as operators optimize recoveries and throughput.

Lower royalty rate: small line, big impact

ACG said oxide production costs in 2026 should benefit from a reduced royalty rate with EMX Royalty Corporation, moving to about 2.25% this year versus 10% last year. Lower royalties can improve margins even if metal prices stay the same, because more of each revenue dollar drops to operating cash flow.

Enriched Ore Treatment Project: “extra” copper-equivalent from what’s already on site

Beyond the main sulphide expansion, ACG also discussed an Enriched Ore Treatment Project at Gediktepe. The company is targeting an additional ~57 kt CuEq from enriched ore and stockpiles on site over a four-year period. In Q4 2025, it completed a scoping study and basic engineering, with permitting, test work, and detailed engineering expected to begin in Q1 2026.

Projects like this can be attractive because they may unlock value from material that is already mined or already accessible—sometimes with lower mining risk than a fully new deposit. However, success will depend on metallurgical performance, permitting, and capex requirements.

Balance sheet snapshot: net debt and what it implies

ACG reported net debt of about US$65 million as of 31 December 2025. Debt can be normal in mining, especially during growth phases, but investors usually evaluate it in context:

• Is debt increasing or decreasing?
• Is cash flow from existing operations enough to support interest and repayments?
• Does the construction schedule require more funding?
• Are commodity prices supportive?

The market will likely weigh ACG’s net debt against the project timeline and the risk of any delays. If the sulphide expansion starts producing on schedule, the company could move from construction risk to ramp-up execution, which investors often prefer.

Management message: confidence, but the next steps must prove it

In commentary, CEO and Chairman Artem Volynets emphasized that the company is proud of outperformance and believes it is well positioned to complete the transition to a copper producer. The message is optimistic, and the data points—beating guidance, lower C1 costs, project progress—support that tone.

Still, in mining, the market typically asks for proof in three phases:

1. Build phase: stay on time and on budget.
2. Commissioning phase: start up safely and achieve stable throughput.
3. Ramp-up phase: hit guidance consistently, with reliable recoveries and costs.

ACG’s update suggests phase one is going well. Phase two and three will be the critical story of 2026.

Upcoming investor presentation: what to listen for

The company said management will provide a live presentation via Investor Meet Company on 26 January 2026 (12:00 GMT). Presentations like these can add color beyond the press release—especially around commissioning timelines, capex remaining, and operational bottlenecks that may not appear in headline metrics.

For readers who want to follow the company directly, you can usually find official updates and presentations via the company’s website. For example: ACG Metals official website.

Why this update matters in the bigger copper market narrative

Copper is often called “the metal of electrification” because it is widely used in power networks, electric vehicles, charging infrastructure, motors, and renewable energy projects. That doesn’t mean copper prices will only go up—markets are more complicated than that—but it does mean investors pay attention to credible near-term copper supply growth.

ACG’s plan is not just “more production.” It’s a shift toward a commodity that many institutional investors see as strategic. If the sulphide expansion delivers on schedule and within cost expectations, ACG may be able to broaden its shareholder base and potentially reduce the “execution discount” that sometimes applies to companies in heavy build phases.

Key risks and watch-outs (balanced view)

Even a strong update has risks. Here are the main ones investors typically monitor for a company in ACG’s position:

1) Commissioning and ramp-up risk

New plants can face early hiccups—equipment tuning, reagent optimization, and throughput stability. Delays can cost money and reduce investor confidence.

2) Cost inflation and contractor management

Construction peaks often bring more contractors on site. Safety and schedule discipline become harder, not easier, at this stage.

3) Commodity price swings

Gold, silver, and copper prices can move sharply. Royalties, revenue, and margins can change quickly.

4) Permitting and technical risk on “add-on” projects

The enriched ore project could add value, but it depends on permitting, metallurgy, and capital decisions.

FAQs (frequently asked questions)

1) What does it mean that ACG “beat guidance” in 2025?

It means ACG produced more than the top end of the production range it previously told the market to expect. In this case, ACG said it produced 39.2 koz AuEq, around 3% above the upper end of guidance.

2) What is the difference between AuEq and CuEq?

AuEq combines production of gold and other metals into a “gold equivalent” number. CuEq does a similar thing but expresses value as “copper equivalent.” Companies use these measures to summarize multi-metal production in a single headline figure.

3) Why did AISC rise if the company said it improved efficiency?

ACG reported that royalties increased due to higher gold and silver prices. Since AISC includes items like royalties, it can rise even if operating cash costs fall.

4) When does ACG expect to become a copper producer?

ACG stated that the Gediktepe Sulphide Expansion Project is on time and on budget for commercial production by the end of the first half of 2026.

5) What is ACG guiding for 2026 production?

ACG guided to 20–22 ktpa CuEq production in 2026, alongside expected AISC of about US$2.40–US$2.60 per pound CuEq.

6) What is the Enriched Ore Treatment Project and why does it matter?

It is an additional project aimed at processing enriched ore and stockpiles already on site, targeting around 57 kt CuEq over four years. If successful, it could add extra production without relying solely on new mining areas.

7) How much debt does ACG have?

ACG reported net debt of about US$65 million at 31 December 2025. Investors typically compare that figure against cash flow, remaining capex, and project timelines.

Conclusion: strong 2025 execution, but 2026 is the real test

ACG Metals’ FY and Q4 2025 update shows a company that is executing well: it beat production guidance, improved cash costs, and advanced its sulphide expansion on schedule and on budget. Those are meaningful achievements in a sector where delays and overruns are common.

Now the spotlight shifts to 2026. The market will watch for smooth commissioning, stable ramp-up performance, and delivery against the new copper-equivalent guidance. If ACG can translate “project progress” into “reliable copper output,” the company may be positioned for a new phase of investor interest as a growing copper producer.
