metallurgical technical

"announced that positive metallurgical test work results completed from the company's Golconda Project"

Metallurgical describes the processes and techniques used to extract, separate, refine and test metals from ore or recycled material, including crushing, melting, chemical separation and quality assays. For investors, metallurgical performance determines how much saleable metal a project yields, how costly and risky production will be, and whether a mine or plant can meet product and environmental standards—like the recipe and kitchen that turn raw ingredients into a marketable product.

drill core technical

"assessing gallium, silver and gold recovery from unoxidized drill core and RC chips from the Golconda"

A drill core is a long, cylindrical sample of rock pulled from beneath the surface during exploration drilling that preserves the layers and minerals exactly as they occur underground. Investors care because lab tests on core reveal what minerals and concentrations are present and how they’re distributed, which is the primary evidence used to estimate a deposit’s size, quality and commercial potential—like reading the cross‑section of a layered cake to judge whether it’s worth buying.

RC chips technical

"gallium, silver and gold recovery from unoxidized drill core and RC chips from the Golconda Project."

RC chips are semiconductor components that use tiny resistor-and-capacitor circuits to set timing, smooth signals, or filter noise inside electronic devices—think of them as the timing gears and shock absorbers of a gadget’s electronics. Investors watch them because their demand, supply constraints, or price swings reflect broader trends in consumer electronics, industrial equipment and automotive markets, affecting manufacturers’ revenues, costs and profit margins.

flotation technical

"showed gallium up to 70% recovery, using screening and flotation; silver up to 97% recovery;"

Flotation is the process where a privately held business makes its shares available to the public by listing them on a stock exchange, commonly called an initial public offering (IPO). For investors it matters because flotation creates a market price and trading chance for those shares, signals a company's growth plans and need for capital, and changes how the business is governed — like a small shop selling ownership stakes to many new customers to raise money and spread risk.

sericite technical

"approximately 90% of the total gallium at Golconda is hosted in sericite, a type of muscovite,"

Sericite is a fine-grained, silky white mica mineral often found as a soft, flaky coating in altered rocks and in industrial materials like paints and ceramics. For investors, its presence in a rock pattern can be a useful clue that hot fluids once moved through the area and concentrated metals such as gold or copper — like finding chalky footprints that can lead explorers to a potential ore deposit — and it can also influence processing costs and product value.

muscovite technical

"total gallium at Golconda is hosted in sericite, a type of muscovite, making it the primary"

Muscovite is a common mineral in the mica family that forms thin, flexible sheets like the pages of a book; those sheets are heat-resistant and electrically insulating. Investors care because muscovite is a raw material used in electronics, electrical insulation, paints, cosmetics and construction, so its availability, quality and price can affect makers of components and materials and therefore the revenues and costs of companies in mining, manufacturing and tech supply chains.

TUCSON, Ariz., April 8, 2026 /PRNewswire/ -- G50 Corp Limited (ASX: G50; OTCQX: GFTYF) announced that positive metallurgical test work results completed from the company's Golconda Project in Arizona, confirm the ability to produce a gallium-rich concentrate using proven, low-cost processing methods. These results support the potential development of a primary gallium supply source out of the U.S.

The exploratory metallurgical test work was undertaken by SGS Lakefield, assessing gallium, silver and gold recovery from unoxidized drill core and RC chips from the Golconda Project. Gallium grades increased between 150% to 200% and strong recoveries showed gallium up to 70% recovery, using screening and flotation; silver up to 97% recovery; and gold via floatation with 82% recovery.

"These exceptional results support a staged, low-capital pathway targeting early development of saleable gallium concentrate with optional precious-metal by-products," said Mark Wallace, managing director and CEO of G50. "These results significantly de-risk our Golconda Project and show that Golconda can potentially be a supplier of gallium for US domestic needs."

Additional information on these results can be found at: https://cdn-api.markitdigital.com/apiman-gateway/ASX/asx-research/1.0/file/2924-03076323-2A1664878&v=undefined.

"Last year we announced a mineralogy breakthrough where test work had shown that approximately 90% of the total gallium at Golconda is hosted in sericite, a type of muscovite, making it the primary target for concentration and extraction," said Wallace. He added that the presence of gallium in highly anomalous levels in sericite and separate from the precious metal bearing sulfides at the project, are considered positive characteristics that can aid in the concentration and extraction of gallium in these rocks using traditional mineral processing integrating this project into domestic supply chains.

G50 Corp (https://www.g50corp.com) is an exploration company focused on the southwestern U.S. The company's flagship Golconda Project comprises both patented and unpatented claims and is ideally positioned near existing mining infrastructure and logistics hubs to meet the United States' growing demand for domestic mineral resources, such as gallium. It is believed to be one of the few projects in the U.S. actively exploring the mining of this element.
