Hot Chili Trades at a Third of Peers as La Verde Reshapes Costa Fuego

The gap between what Hot Chili Limited’s Costa Fuego project is worth on paper and what it trades for in the market has been widening for 15 months. La Verde, the copper-gold porphyry discovery announced in December 2024, may be the event that closes it. This is not a bolt-on addition. La Verde is a potential structural transformation of the project’s economics, with a maiden mineral resource estimate (MRE) targeting approximately 500 million tonnes expected later in 2026 and a revised prefeasibility study (PFS) commenced in May 2026 set to formally recalibrate NPV, IRR, payback period, and cost quartile position. What follows is a data-grounded breakdown of each layer: the baseline the existing PFS established, what La Verde’s drill results are showing, the three economic levers the discovery pulls, why updated commodity prices add a separate uplift, and where the stock sits relative to North American peers. This is the analytical framework for evaluating whether the near-term catalyst sequence represents a genuine re-rating event.

What the existing prefeasibility study actually established

Before any La Verde projection lands, the baseline matters. The March 2025 PFS remains the current formal economic reference point for Costa Fuego, and it already positions the project as globally significant on its own.

Probable ore reserves stand at approximately 502 Mt at 0.37% Cu, 0.10 g/t Au, 0.49 g/t Ag, and 97 ppm Mo. The capital-to-NPV cash flow index sits at approximately 1:1. One separate company news item references a 14-year mine life for the project; CEO Christian East has stated 20 years in company presentations.

The coastal location advantage that underpins the cost position

Costa Fuego sits at low elevation on the Chilean coastline, adjacent to the Pan-American Highway and near port facilities. This is not a detail. It is the structural reason capital intensity sits in the bottom quartile relative to comparable projects. Andean copper peers at 3,000-4,000 metres elevation are estimated to cost roughly double Costa Fuego’s capital requirement, facing more complex water sourcing and logistics challenges. That cost advantage is durable regardless of which PFS scenario is being evaluated.

La Verde as a geological proposition: what the drilling is showing

La Verde sits approximately 30-35 km south of the planned Costa Fuego central processing hub at Productora. Its mineralisation footprint extends approximately 1,000 m by 800 m, remains open in all directions and to depth, and commences at or near surface.

La Verde fits the geological profile that makes porphyry copper deposits among the most sought-after development targets in the world: wide, continuous mineralisation from surface, an expanding footprint in all directions, and a grade profile that supports bulk-tonnage extraction at low unit costs.

The drill results provide the physical evidence base for the resource estimate that has not yet been published. Three intercepts define the scale:

• 174 m at 0.4% Cu and 0.1 g/t Au from shallow depths
• 308 m at approximately 0.5% Cu and approximately 0.3 g/t Au from shallow depths
• 391.1 m at 0.51% CuEq from surface (hole DKD044)

Headline intercept: Hole DKD044 returned 391.1 m at 0.51% CuEq from surface, demonstrating wide, continuous mineralisation from the top of the hole.

That third intercept, nearly 400 metres of continuous copper-gold mineralisation starting at surface, is the result that underpins the starter-pit concept central to the revised economics. La Verde also carries a proportionally higher gold content relative to the main Costa Fuego deposits, a characteristic with direct economic relevance when gold prices have moved significantly since the original PFS.

Three rigs were operating at La Verde at the time of CEO Christian East’s most recent public commentary, with a fourth scheduled to arrive. The maiden MRE is targeted for release by end of 2026. The approximately 500 Mt resource figure represents a management target stated by CEO East, not a published JORC resource.

The JORC resource classification standards establish the framework that ASX-listed explorers must follow when reporting Inferred, Indicated, and Measured resource estimates, with independent competent person sign-off being the gating requirement before any tonnage or grade figure can be disclosed to the market.

The three levers La Verde pulls on project economics

CEO Christian East has outlined three discrete mechanisms by which La Verde integration is expected to improve Costa Fuego’s economics. The following projections are management expectations from the revised PFS in progress, commenced May 2026 and targeted around Q2 2027. None have been published in a formal revised study.

Lever one: front-loaded grade and starter-pit economics

La Verde’s shallow, higher-grade mineralisation supports a starter-pit concept that could deliver approximately five years of higher-grade ore feed at the front end of the mine plan. The effect on early cash flows is direct: the payback period is projected to compress from approximately 4.5 years to approximately 2.5 years. For project financing discussions and strategic partner negotiations, that compression is the single most commercially significant metric in the revised study.

Lever two: mine life and annual throughput expansion

La Verde’s resource tonnage is expected to extend the mine plan from 20 years toward 25-30 years and support an increase in annual copper equivalent production from approximately 120,000 tonnes to approximately 150,000 tonnes. The hub-and-spoke model, with La Verde feeding material to the central Productora processing facility, preserves the existing infrastructure economics while expanding scale.

Lever three: operating cost quartile shift

Higher gold credits from La Verde and improved front-end grades are projected to move C1 cash costs from the second quartile into the first quartile of global cash cost rankings. The gold proportion at La Verde is higher than at the main hub, meaning gold by-product credits contribute more per tonne processed to the net cost calculation.

Each lever is independently verifiable once the revised PFS is published. This framework gives investors the structure to track which projections are confirmed, partially confirmed, or revised when the study lands.

Why commodity prices add a separate, additive uplift layer

The La Verde integration covered above operates at the project’s physical level: grade, tonnage, mine life. Commodity prices add a separate layer of economic improvement that does not depend on drilling outcomes.

The original PFS used a long-term copper price of USD $4.30/lb. Updated long-term consensus has moved to approximately USD $4.90/lb. The original gold assumption was USD $2,280/oz; long-term consensus now sits at approximately USD $3,600/oz, an increase of approximately 30%.

• Copper price movement: USD $4.30/lb to approximately USD $4.90/lb
• Gold price movement: USD $2,280/oz to approximately USD $3,600/oz
• Estimated NPV contribution from copper price movement alone: approximately USD $600 million in additional post-tax NPV

According to CEO Christian East and company presentation materials, the copper price movement alone is estimated to contribute an additional USD $600 million in post-tax NPV, separate from any La Verde integration effect.

La Verde’s proportionally higher gold content makes the gold price movement disproportionately beneficial for the integrated project. The revised PFS, with projected annual revenue estimated at over USD $2 billion on a mine life heading toward 30 years, will incorporate both sources of uplift simultaneously.

The distinction matters for risk assessment. The commodity price uplift is anchored by market consensus, not contingent on drilling success. It adds a floor under the revised PFS outcome regardless of where the maiden La Verde MRE lands within management’s target range.

The disconnect between rising commodity prices and flat equity valuations is not unique to Hot Chili: the broader junior copper explorer re-rating that many analysts anticipated has not materialised across the sector, and the structural reasons behind that lag are relevant to assessing whether Hot Chili’s specific catalyst sequence can break the pattern.

How the stock is priced versus where comparable transactions have occurred

The valuation gap is specific enough to quantify. According to company-presented peer comparisons from investor materials, North American peer copper developers trade at approximately USD $0.11/lb of copper reserves on an in-ground basis. Hot Chili currently trades at approximately USD $0.038/lb.

La Verde integration expanding the resource from approximately 1 billion tonnes to approximately 1.5 billion tonnes directly expands the denominator in that per-pound calculation. The re-rating ceiling widens mechanically as the resource base grows.

Third-party capital has already assigned value to the discovery. OR Royalties Inc. paid USD $15 million for a net smelter return royalty over La Verde, confirming external validation of the deposit’s materiality. Hot Chili’s cash position stands at approximately AUD $46 million following the transaction, with approximately USD $60 million allocated for current-year development, environmental assessment, and resource activities.

ASX-listed copper developers with large Chilean assets have historically traded at discounts to North American peers. Liquidity differences, jurisdiction and currency perceptions, and the lag between discovery and formal resource inclusion all contribute. Whether the gap closes depends on the revised PFS converting management projections into published metrics that institutional investors and major producers can act on.

The catalyst sequence that determines when the re-rating occurs

The investment thesis is anchored to a specific sequence of events, each with an approximate timeline:

1. Maiden La Verde MRE (targeted later in 2026): First JORC-compliant quantification of La Verde’s tonnage and grade. Moves the approximately 500 Mt management target to a published resource and is the prerequisite for the revised PFS.
2. Revised Costa Fuego PFS (commenced May 2026; targeted around Q2 2027): Incorporates La Verde and a larger open-pit scenario at Cortadera. External engineering firm Sencko is collaborating. This is the primary inflection point, converting management projections into published study metrics.
3. EIA submission (targeted around Q2 2027): A critical derisking step for attracting major strategic partners.
4. Final investment decision (targeted approximately 2029): Requires substantial additional capital and is contingent on the preceding milestones.

The risks attached to this sequence are material:

• The maiden La Verde MRE may deliver tonnage or grade below the approximately 500 Mt management target
• The revised PFS timeline is a forward-looking target, not a commitment; delays are possible
• Permitting in Chile carries inherent uncertainty
• The path from PFS to final investment decision requires substantial additional capital and strategic partner support

Each milestone either de-risks the thesis or requires re-evaluation. The revised PFS in particular is the conversion point between management projections and market-actionable data.

The catalyst sequence structure at Costa Fuego follows a pattern common to milestone-driven re-rating theses in the resources sector: each published study converts management projections into market-actionable data, progressively de-risking the thesis and expanding the institutional investor base that can underwrite the next stage of capital.

La Verde changes the scale of the conversation, not just the numbers

Three analytical claims run through this assessment. The baseline PFS already positions Costa Fuego as a globally competitive copper development with bottom-quartile capital intensity and a USD $1.22 billion post-tax NPV. La Verde integration and commodity price movement together point toward a materially higher revised study outcome, with management projecting NPV toward USD $2 billion and IRR toward the mid-30% range. The current in-ground valuation implies neither improvement has been priced in, with the stock trading at roughly a third of the North American peer average on a per-pound basis.

The central risk is equally clear: all revised economics are management expectations until the revised PFS is published. The maiden La Verde MRE, targeted for later in 2026, is the first checkpoint. The revised PFS, targeted around Q2 2027, is the event that converts projections into market-actionable facts. Until then, the thesis rests on the plausibility of the drill results, the credibility of the management team’s track record, and the structural advantages of a coastal Chilean copper project in a market where large-scale independent copper assets are increasingly scarce.

The structural copper supply shortfall facing the market through the 2030s is the macro backdrop that makes a project of Costa Fuego’s scale increasingly scarce; large, permitted, low-cost copper development assets are rarely available to strategic buyers at the development stage.
