metallurgical test work technical

"The exploratory metallurgical test work was undertaken by SGS Lakefield..."

Laboratory and pilot-scale experiments that determine how a mineral deposit can be processed to recover valuable metals, measuring likely recovery rates, suitable processing methods, costs and technical challenges. For investors, this work is like testing a recipe before opening a restaurant: it shows whether the resource can be turned into saleable metal efficiently and predictably, which directly affects production forecasts, cost estimates and project risk.

drill core technical

"...recovery from unoxidized drill core and RC chips from the Golconda Project."

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.

flotation technical

"...using screening and flotation; silver up to 97% recovery; and gold via floatation..."

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

"...sericite, a type of muscovite, making it the primary target for concentration and extraction..."

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.

sulfides technical

"...separate from the precious metal bearing sulfides at the project, are considered positive..."

Sulfides are minerals in which one or more metals are chemically bonded to sulfur, for example copper sulfide or nickel sulfide; think of them as metal atoms glued to sulfur atoms inside a rock. They matter to investors because sulfide ores often host the metals mining companies sell and influence how easily and cheaply those metals can be extracted, processed and sold, as well as environmental risks and cleanup costs.

mineral processing technical

"...using traditional mineral processing integrating this project into domestic supply chains."

Mineral processing is the set of industrial steps that turn raw rock pulled from a mine into concentrated metal- or mineral-rich material ready for sale or further refining. Think of it like a kitchen process that washes, breaks up, and sorts ingredients to get the useful parts; the efficiency, cost and environmental footprint of those steps directly affect a mining project’s output, profit margins, and regulatory risks, so investors watch it closely.

critical minerals technical

"...growing demand for domestic mineral resources, such as gallium. It is believed to be one of the few projects..."

Materials needed to build modern technologies—like batteries, electronics, renewable energy systems and defense equipment—that have few easy substitutes and often come from a small number of countries or mines. Investors care because their supply can be disrupted, expensive or slow to increase, which affects the cost, availability and growth prospects of companies and industries that rely on them; think of them as critical spare parts for the global economy.

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.
