1. Ownership and Share Structure Information

The information listed above was updated on the date this article was published and was compiled from information from the company and various other data providers.

Supply constraints in precious and base metals markets are creating notable opportunities for junior explorers focused on silver, copper, gold, and antimony. Grafton Resources Inc. (GFT:CSE; PMSXF:OTC) has positioned itself to benefit by consolidating a new exploration package in a proven district.

Metals Markets Face Supply Pressure and Volatility

Recent market updates highlight tightening physical supply for copper in China alongside silver price rebounds driven by industrial demand and import restrictions in key markets. These conditions underscore the value of early-stage projects with demonstrated mineralization potential near operating mines.

Why Grafton Resources Stands Out in Chile

Grafton Resources Inc. (GFT:CSE; PMSXF:OTC) announced the establishment of the Caldera silver-copper-gold-antimony project in Chile's Pedernal district of the Valparaiso region. The company consolidated multiple concessions targeting favorable geology within the Morro Hediondo Caldera region by combining newly staked ground, the Silver One concessions, and a historic geological database.

Project Assets and Exploration Potential

The Caldera project includes 10 newly staked exploration concessions totaling 2,100 hectares covering continuous trends of mineralized vein outcrop and epithermal alteration. It also incorporates the Silver One concessions from a prior letter of intent with Asesorias e Inversiones Sol SpA, together with the historic database used to select concessions. The package covers a principal northwest-southeast vein trend, a parallel northeast-southwest trend, and surrounding alteration targets roughly 10 kilometers from the producing El Bronce mine.

Key highlights include 3.8 kilometers of secured vein trends across continuous outcrop that remain undrilled. Historical samples reached up to 4.0 grams per tonne gold, 300 grams per tonne silver, and 12.4 percent copper within epithermal vein systems. Vein systems previously worked by artisanal miners and zones of epithermal alteration have not been tested with modern methods. Epithermal systems refer to mineral deposits formed at shallow depths from hot fluids.

Framework Agreement and Acquisition Terms

The company, its wholly owned Chilean subsidiary, and AIS entered into a framework agreement, two definitive option agreements, and a share consideration agreement dated July 21, 2026, replacing the prior letter of intent. Grafton received an option to acquire a 100 percent interest in the Silver One property through cash payments totaling US$248,000, consisting of US$148,000 upon signing and US$100,000 within 24 months, plus share consideration valued at US$400,000 issued in two equal tranches. The option remains subject to Canadian Securities Exchange approval.

Historic Database Supports Targeting

Concession selection drew from a historic sampling database obtained through agreements with AIS. The database contains 150 samples analyzed using ICP multielement methods, gold fire assay, and selected base metals by atomic absorption. Results showed 92 percent of samples returned anomalous copper values greater than 0.1 percent copper, 24 percent exceeded 3.0 percent copper, and the highest value reached 12.4 percent copper. Twenty-five percent of silver samples exceeded 100 parts per million, with anomalous silver samples also returning elevated antimony, arsenic, and mercury values. The sampling occurred in 2021, with most results supported by laboratory certificates, though the work lacks formal quality assurance and quality control and should be treated as a historical initial indicator only.

Analyst Perspective on Portfolio and Valuation

In commentary, Michael Ballanger described Grafton Resources as en route to building a powerful portfolio of projects all in Chile and all secured by the Fitzroy team. He characterized the Caldera project as a silver-gold-copper prospect located proximate to an existing operating mine with huge potential. Ballanger noted the company had only 26 million shares issued and outstanding and suggested it would take modest demand to push the stock into the CA$50 million market cap range, close to CA$2.00. He assigned a Strong Buy recommendation with a target price of CA$2.00.

Key Investor Takeaways

• Grafton Resources has consolidated a new silver-copper-gold-antimony project in Chile near an operating mine using historic data and new staking.
• Historical sampling indicated high-grade copper up to 12.4 percent along with gold and silver values in undrilled vein trends.
• The company holds a low share count of 26 million, which could amplify moves on increased investor interest, according to analyst commentary.
• Metals markets show signs of physical supply tightness in copper and industrial demand support for silver.
• Reconnaissance work has started, and results will be reported as available.
• The option agreement for Silver One property requires regulatory approval and staged payments.

Geological Reconnaissance Underway at Caldera

Grafton Resources has begun a geological reconnaissance program across the granted concession areas at the Caldera project. The work will include resampling historically mineralized sites and extending sampling coverage across the consolidated project area.

The program aims to produce preliminary geological models for each occurrence within the project. Results from the reconnaissance program will be reported as they become available.

Share Structure and Ownership Snapshot

¹Management and insiders own 13.55 percent of Grafton Resources, with the remainder held by retail investors. The 52-week range stands at CA$0.22 to US$43.98. Market capitalization is CA$10.99 million with 16.23 million free float shares.
