Rio2 Starts First-Phase Drilling at Condestable in Peru

Rio2 Limited (OTCQX: RIOFF) said on September 22, 2026 that it has begun a first-phase surface drilling program and district-scale exploration at its Condestable copper mine in Peru, following geological mapping of a 3-km by 1.2-km northeast-trending corridor linking Condestable, Raul and Vinchos.

Rio2 Limited (OTCQX: RIOFF) has moved from mapping to drilling at its Condestable copper mine in Peru, telling the market on September 22, 2026 that it has begun a first-phase surface drilling program alongside broader district-scale exploration work. The announcement came as part of a company-wide update that also covered the Fenix Gold Mine in Chile and the Kalzas Tungsten Project in Canada — three assets, three metals, three jurisdictions.

The drilling follows a comprehensive geological mapping campaign over a 3-kilometre by 1.2-kilometre northeast-trending corridor that runs between Condestable, Raul and Vinchos. In plain terms, the company spent the preceding phase walking the surface and tying what outcrops there to what it already sees underground in the operating mine. Rio2 said that exercise strengthened the correlation between surface and underground geology and sharpened its understanding of what controls the copper-gold-silver sulphide mineralization it is mining.

What the mapping actually established at Condestable

Two mineralization styles are in play. The first sits within brecciated mantos — flat-lying, sheet-like bodies — ranging from 1 to 10 metres in thickness, with strong lithological controls tied to volcanic breccias running parallel to stratification. The second is vein-hosted, with widths from centimetres to more than 3 metres. The dominant vein orientation is northwest, with a secondary northeast-trending set.

That detail matters more than it sounds. A deposit with a clear structural control is a deposit you can vector on: if the geologists know that the veins repeat on a northwest trend and that the mantos follow specific volcanic breccia units, then surface drill holes can be placed on geology rather than on a grid. Mapping that reconciles with the mine face is the cheapest de-risking step available in exploration, and it is normally the step that gets skipped when budgets are thin.

Condestable is a producing operation, which changes the calculus of a drill program. Exploration around an existing mine, with existing plant, existing permits and an existing workforce, converts to mill feed faster than a greenfield discovery of the same tonnage. Any material extension along the Condestable–Raul–Vinchos corridor would land in a system that already has somewhere to send the rock.

A three-metal portfolio in one release

The update, carried by INN Precious Metals, packages copper in Peru, gold in Chile and tungsten in Canada into a single disclosure. That is an unusual spread for a company of Rio2's size, and it cuts both ways.

On the constructive side, the three metals answer to different demand drivers. Copper is levered to electrification and grid build-out. Gold is a monetary and risk asset. Tungsten is a defence and industrial-tooling input that sits on Western critical-minerals lists precisely because supply is concentrated outside North America. A company with exposure to all three is not making a single macro bet.

On the cautious side, exploration capital is finite, and three programs across three continents compete for the same dollars and the same technical attention. Investors reading a company-wide update should be asking which asset gets the marginal dollar and on what timeline. The Condestable drilling is described as first-phase, which implies results that will determine whether a second phase is funded.

How the shares are trading through the news

The market response has been muted. Rio2's OTCQX line, RIOFF, was quoted at 2.57 as of 14:01 GMT on September 22, 2026, down 0.77% from a prior close of 2.59, with a session range of 2.56 to 2.65. The stock traded above its close early and gave the gain back — the signature of an exploration update that adds information without adding an assay result.

That is the right read. First-phase drilling programs are announcements of intent. They tell the market that holes are going in the ground and that the geological model has been tightened. They do not tell the market what the drill found, because the drill has not yet reported. Repricing, if it comes, arrives with grades and intercept widths.

The broader tape offered no push in either direction. The S&P 500, via SPY, sat at $773.90, up 0.05% on the day against a prior close of $773.50. The Nasdaq 100 tracker QQQ was the stronger of the three majors at $744.89, up 0.46%, while the Dow 30 proxy DIA slipped 0.10% to $519.25. A flat index day means the small move in RIOFF is company-specific rather than beta.

One practical note for investors screening the name: Rio2 carries three listings — TSX: RIO, OTCQX: RIOFF and BVL: RIO in Lima. The TSX and Lima symbols are not unique across global exchanges, so quote screens can return an unrelated security under the same three letters. Confirm the exchange before trading.

The next data points that matter

Three things are worth watching from here.

• Drill results from phase one at Condestable. Widths and grades within the 1-to-10-metre mantos, and whether the northwest vein set carries continuity away from the known mine workings.
• Whether the corridor holds up at district scale. The 3-km by 1.2-km mapped area between Condestable, Raul and Vinchos is the thesis. Drilling either confirms that the three centres belong to one system or shows they do not.
• Capital allocation across Peru, Chile and Canada. Fenix and Kalzas were included in the same update; the size and sequencing of their programs relative to Condestable will show where management sees the best return per dollar.

For now, the signal is procedural rather than economic: a producing copper mine has a mapped exploration corridor and a rig turning. The value of that only becomes measurable when the core comes back.

Frequently asked questions

What did Rio2 announce on September 22, 2026?

Rio2 Limited issued a company-wide exploration update covering three assets. The headline item was the start of a first-phase surface drilling program and district-scale exploration activities at its Condestable copper mine in Peru. The update also covered the Fenix Gold Mine in Chile and the Kalzas Tungsten Project in Canada.

What is the 3-km by 1.2-km corridor at Condestable?

It is a northeast-trending area that Rio2 covered with a comprehensive geological mapping campaign, running between the Condestable, Raul and Vinchos centres. The company said the mapping strengthened the correlation between surface geology and underground mine geology and refined its understanding of the controls on copper-gold-silver sulphide mineralization.

What style of mineralization does Condestable host?

Two styles. Mineralization occurs within brecciated mantos ranging from 1 to 10 metres in thickness, with strong lithological controls tied to volcanic breccias parallel to stratification. There is also vein-hosted mineralization with widths from centimetres to more than 3 metres, dominated by a northwest orientation with a secondary northeast-trending set.

How did Rio2 shares react to the exploration update?

The response was muted. The OTCQX line, RIOFF, was quoted at 2.57 as of 14:01 GMT on September 22, 2026, down 0.77% from a prior close of 2.59, having traded in a session range of 2.56 to 2.65. A first-phase drilling announcement adds information but no assay results.

Where does Rio2 stock trade?

Rio2 Limited carries three listings: TSX: RIO in Toronto, OTCQX: RIOFF in the United States and BVL: RIO on the Lima exchange. Because the three-letter symbols are not globally unique, quote screens can return an unrelated security, so investors should confirm the exchange before placing an order.

Why does a three-metal portfolio matter for Rio2?

Copper, gold and tungsten answer to different demand drivers: electrification and grid build-out for copper, monetary and risk demand for gold, and defence and industrial tooling for tungsten. Spreading across all three reduces reliance on a single macro outcome, but it also means three exploration programs compete for the same finite capital.
