Key Terms

sericite, fuchsite, pyrite, arsenopyrite, +4 more

8 terms

sericite technical

"strong to intense alteration consisting of fuchsite, sericite, silicification"

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.

fuchsite technical

"strong Sericite-Fuchsite alteration with Py and AspyExtend Mineralization"

A green, flaky mineral in the mica family that gets its color from chromium and commonly appears in metamorphic rocks. Investors watch for fuchsite because its presence can act like a visible clue in a geological treasure hunt—signaling potential chromium or other mineralization nearby and influencing the value and processing of a mining prospect, or occasionally being marketed for decorative and gem uses.

pyrite technical

"quartz flooding, disseminated pyrite, arsenopyrite and local galena"

Pyrite is a common metallic mineral made of iron and sulfur, often called “fool’s gold” because its shiny, brassy appearance can be mistaken for real gold. For investors, pyrite matters because its presence influences ore value and processing costs—it can dilute precious metal grades, increase sulfur-related treatment and environmental cleanup expenses, and create acid runoff risks at mining sites, much like unexpected rocks in a gravel pile that change what you can do with the load.

arsenopyrite technical

"with associated quartz stockwork over a minimum width of 30m... arsenopyrite"

Arsenopyrite is a common mineral made of iron combined with arsenic and sulfur; it often appears in rocks that also contain gold and other metals. For investors, it matters because arsenopyrite can lock valuable metals into a hard-to-treat form and release toxic arsenic during mining and processing, which can increase extraction costs, slow production, and raise environmental and regulatory liabilities—like finding a valuable item inside a locked safe that is expensive to open safely.

galena technical

"disseminated pyrite, arsenopyrite and local galena with all primary textures destroyed"

Galena is a dense, metallic mineral that is the main natural source of lead and often contains silver; think of it as a rock that acts like a piggy bank holding valuable metals. For investors, galena matters because the amount and quality of this mineral in a mine determine how profitable mining projects and metal supplies can be, and its presence affects commodity prices, production costs, and potential environmental cleanup liabilities.

tourmaline technical

"Abundant quartz vein and flooding is also present including local tourmaline veinlets"

A crystalline mineral often used as a gemstone and in some industrial applications; tourmaline is valued for its range of colors and for physical properties that can convert mechanical pressure into electrical charge. For investors, its importance comes from demand in jewelry markets and niche industrial uses (like sensors or electronic components), so changes in consumer taste or industrial tech can affect supply, pricing and company revenues much like shifts in demand for any commodity.

quartz stockwork technical

"associated quartz stockwork over a minimum width of 30m"

A quartz stockwork is a dense, crisscrossing network of quartz-filled cracks and tiny veins within rock that often host valuable metals like gold or copper. For investors, it matters because such a network can indicate widespread mineralization across a deposit—offering potential upside—but also means the ore may be patchy and harder to predict and mine, which can increase exploration risk and production costs.

national instrument 43-101 regulatory

"a qualified person as defined in National Instrument 43-101, has reviewed"

National Instrument 43-101 is a set of rules and guidelines that govern how mineral exploration and mining companies must report information about their projects. It ensures that the details shared with investors are accurate, consistent, and reliable—similar to how a detailed, verified blueprint ensures a building’s safety. This helps investors make informed decisions based on trustworthy information about a company's mineral resources.

• Strong Sericite-Fuchsite alteration with Py and Aspy
• Extend Mineralization both East and West

Thunder Bay, Ontario--(Newsfile Corp. - November 27, 2025) - Metals Creek Resources Corp. (TSXV: MEK) (OTC Pink: MCREF) (FSE: M1C1) (the "Company" or Metals Creek), is pleased to announce the completion of a surface trenching program within the Naybob West Zone which is located 400m west-northwest of the past producing Naybob Gold Deposit on the Ogden Gold Project in Timmins, Ontario. The Ogden Gold Project is a 50/50 Joint Venture with Discovery Silver Corp ("Discovery"), with the Company serving as the operator.

This surface trenching program is follow-up to results from a recent prospecting/mapping program (See news release, October 28, 2025) on Naybob West which returned high-grade mineralization ranging from 0.054 grams per tonne (g/t) to 12.3 g/t Gold (Au). The main focus of this program was to further define the orientation and nature of the gold mineralization as well as further expand both to the east and west the strike extent of this zone of mineralization. This zone of mineralization is hosted within a broad zone of strong to intense alteration consisting of fuchsite, sericite, silicification and iron carbonate with associated quartz stockwork over a minimum width of 30m. Within this pervasive zone of alteration is a discrete zone of mineralization with quartz flooding, disseminated pyrite, arsenopyrite and local galena with all primary textures destroyed.

Trenching was successful in expanding mineralization along strike both in the east and west direction. Intense alteration (See Figure 1) consisting of fuchsite, sericite, silicification and carbonatization was identified with associated pyrite, arsenopyrite mineralization. Abundant quartz vein and flooding is also present including local tourmaline veinlets which is sometimes a key indicator for potential gold mineralization. This program saw the collection of 60 surface grab samples. Mineralization remains open both to the east and west with mineralization traced for approximately 70 meters(m). Structural folding is also present with the orientation of this zone of alteration changing from an easterly to north easterly direction. This change in orientation is highly important in that northeast trending structures within the Timmins Gold Camp is considered to be highly prospective for the emplacement of gold mineralization.

In addition to the trenching and subsequent sampling, 6 lines of soils sampling were conducted over what is interpreted to be along strike of the alteration package. With the onset of winter conditions, additional trenching was unable to be completed. (Note: The surface grab samples described in this news release are selective by nature and are unlikely to represent average grades of the property).

The Ogden Gold Project is an exploration staged project located within the prolific Timmins Gold Camp. It is a part of a joint venture agreement between Metals Creek Resources and Discovery Silver Corp. The property is located in Ogden Township and covers 8km of strike length of the Porcupine-Destor Break, the key conduit for gold mineralization in the Timmins Gold Camp.
