About Lannister Mining

What is Lannister Mining?
Lannister Mining is a mineral exploration company focused on the Basin Gulch gold-silver property in west-central Montana. The property hosts near-surface gold-silver mineralization, sits within a consolidated package of 11 patented and 53 unpatented claims covering 1,107 hectares, and has seen more than 320 historical drill holes. The company plans further exploration and resource development.
Where is the Basin Gulch property?
Basin Gulch is in west-central Montana, in the historic Philipsburg Mining District. The company describes year-round access from Philipsburg on paved and well-maintained gravel roads, and the property is about one hour from Butte. According to the company, the district led the original US silver boom of the late 1800s.
Is Lannister Mining producing gold?
No. Lannister Mining is an exploration company, not a producer. Its work at Basin Gulch centers on historical drilling data, new work programs, and building toward a future maiden mineral resource estimate. Revenue from gold sales would only become possible much later, after resource definition, economic studies, permitting and development.
What metals is Lannister Mining exploring for?
Gold and silver. The Basin Gulch property hosts gold-silver mineralization that the company describes as near surface and hosted in oxides. Historical trench results reported by the company include both gold and silver values, such as 5 g/t Au and 54 g/t Ag over 34 meters.
Who leads Lannister Mining?
Jim Greig is CEO and a director, with more than 25 years of experience advancing and developing projects. He was a founder, President and Director of Thesis Gold (formerly Benchmark Metals). Kelvin Lee is CFO, with over 15 years of financial management experience at publicly traded companies. The full board and advisory board are on the team page.
What companies has the Lannister Mining team been involved with?
Lannister Mining says many of its co-founders or senior executives were also involved with K92 Mining, Fosterville South Exploration, Arena Minerals and Thesis Gold. Director Mario Vetro is a co-founder of K92 Mining, and advisor John Lewins is Chief Executive Officer of K92 Mining Inc., a high-grade gold producer in Papua New Guinea.

The Basin Gulch property

How big is the Basin Gulch land package?
The total land package includes 11 patented claims and 53 unpatented claims covering 1,107 hectares. The property is underlain by a core of patented mining claims surrounded by unpatented mining claims, and the company notes multiple high-priority targets near the historic resource area.
What is the difference between patented and unpatented claims?
In the United States, a patented mining claim is one where the federal government has passed full title to the holder, while an unpatented claim gives the right to explore and develop minerals on public land without owning it. Basin Gulch is primarily on patented land, according to the company, with unpatented claims around that core. Confirm tenure details in the investor presentation.
How much of Basin Gulch is still unexplored?
About two-thirds. Lannister Mining states that two-thirds of the Basin Gulch property is still unexplored, and that mineralization is open at depth, along strike and untested regionally. That leaves room for exploration beyond the historically drilled area, although results from untested ground cannot be known until it is explored.
What does oxide-hosted gold mean?
Oxide-hosted gold sits in rock that has been weathered and oxidized near the surface. Oxide material is often simpler to process than unoxidized sulfide rock, which is why explorers highlight it. Lannister Mining describes Basin Gulch mineralization as hosted in oxides and near surface, with what it calls significant implied mine design optimization flexibility.
How do you get to Basin Gulch?
By road, year round. The company states the property has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and is only one hour from Butte. Road access matters in exploration because it affects drilling costs, crew logistics and the length of the field season.
Does Basin Gulch have a current mineral resource estimate?
Not yet. Lannister Mining describes a future maiden mineral resource estimate that will draw on historical drilling and new work programs. The company says the mineralization is open in multiple directions and at depth, and that future drilling will concentrate on additional mineralized target areas within the property.

Drilling and historical exploration

How many holes have been drilled at Basin Gulch?
More than 320 historical drill holes, according to Lannister Mining. That drilling record is central to the company case: it gives geologists existing data on where mineralization occurs and at what grades, which can guide confirmation drilling and help plan expansion drilling into new areas.
What are the best historical drill results at Basin Gulch?
Highlights reported by the company include 1.8 g/t Au over 162 meters from surface, 0.66 g/t Au over 326 meters from surface, 3.2 g/t Au over 72 meters from surface, 156 g/t Au over 3 meters, and 25 g/t Au over 14 meters. These are historical results, not a current mineral resource estimate.
What does g/t Au mean?
It means grams of gold per tonne of rock. A result of 1.8 g/t Au over 162 meters means a drill hole intersected 162 meters of rock averaging 1.8 grams of gold in each tonne. Grade and length together describe an intercept; neither number means much on its own.
What are trench results?
Trench results come from samples cut along trenches dug across the ground surface, rather than from drill holes. They show what is exposed at or near surface. Lannister Mining reports trench highlights at Basin Gulch including 4 g/t Au and 23 g/t Ag over 146 meters and 25 g/t Au and 45 g/t Ag over 61 meters.
Why does historical drilling matter to investors?
Historical drilling can shorten the path to a resource estimate. Instead of starting from scratch, a company can verify past intercepts with confirmation drilling, then expand from known mineralization. Lannister Mining states that historical drilling and new work programs will be used in a future maiden mineral resource estimate at Basin Gulch.
What is confirmation drilling?
Confirmation drilling re-drills close to historical holes to check that past results can be reproduced with modern methods and quality control. It helps bring older data up to current reporting standards. Lannister Mining says Basin Gulch could host a significant maiden mineral resource estimate after expansion and confirmation drilling of historical intercepts.
What types of drilling do mineral exploration companies use?
The two most common are reverse circulation drilling, which returns rock chips quickly and at lower cost, and diamond core drilling, which recovers solid cylinders of rock for detailed geology and assays. Many programs use both. Methods planned for Basin Gulch would be set out in the company work program announcements and presentation.

How mineral exploration works

What are the stages of mineral exploration?
Mineral exploration generally moves through target generation, early drilling for discovery, resource definition drilling, a mineral resource estimate, economic studies, permitting, and finally development and production. Each stage reduces uncertainty and usually costs more than the last. Basin Gulch sits between extensive historical drilling and a planned maiden resource estimate.
How long does it take to go from exploration to a mine?
Usually many years, often more than a decade. A project typically needs resource definition, several economic studies, environmental work and permits before construction. Timelines vary widely by jurisdiction, deposit type and financing. Lannister Mining has not published a production timeline; its current focus is exploration and resource development.
What is an NI 43-101 technical report?
NI 43-101 is the Canadian standard for public disclosure of scientific and technical information about mineral projects. A compliant technical report is prepared by or under a qualified person. Lannister Mining states there is a clear market premium for NI 43-101 and SK 1300 compliant gold and silver ounces in the USA.
What is S-K 1300?
S-K 1300 is the US Securities and Exchange Commission rule for mining property disclosure by SEC registrants, covering how mineral resources and reserves are reported. Lannister Mining refers to SK 1300 technical reports alongside NI 43-101 when describing the market value of compliant gold and silver ounces in the USA.
What is a maiden mineral resource estimate?
It is the first formal mineral resource estimate published for a project under a recognized reporting standard. It states tonnes, grades and contained metal in defined confidence categories. For Basin Gulch, Lannister Mining plans a maiden estimate that uses historical drilling together with results from new work programs.
Why do mining companies conduct mineral exploration?
Mining companies conduct mineral exploration to find new deposits and to define known ones well enough to decide whether they can be mined economically. Producers explore to replace the ounces they mine, while junior explorers such as Lannister Mining aim to discover and define resources that can be developed or advanced with partners.

What are the risks of investing in a gold exploration company?
Exploration companies usually have no revenue, depend on raising capital, and face the chance that drilling does not confirm or expand mineralization. Metal prices also swing: Sprott reports a 25.3% peak-to-trough drawdown in gold from March 2 through July 16, 2026. Read company disclosure and seek independent advice before investing.
Which is the best gold mining stock to buy?
This site does not recommend stocks or give investment advice. The right choice depends on your goals and risk tolerance: producers have revenue and may pay dividends, while exploration companies offer exposure to discovery and resource growth with higher risk. A licensed financial adviser can help you weigh options, including companies like Lannister Mining.
Is this website investment advice?
No. This site is published by Lannister Mining to explain the company, the Basin Gulch property and mineral exploration in general. It is informational only. Historical drilling results are not a current mineral resource estimate, and investors should review the company disclosure documents and seek professional advice before making decisions.

Compared with other gold and mineral exploration companies

What is the difference between a gold exploration company and a gold mining company?
A gold exploration company searches for and defines deposits; a gold mining company operates mines and sells gold. Explorers like Lannister Mining usually have no production revenue, while producers such as Newmont and Barrick run large operating mines. Many producers also explore, and many explorers aim to become developers.
What are the top 10 gold companies?
Investing News Network lists the top 10 gold-mining companies as Newmont, Agnico Eagle Mines, Barrick Mining, Navoi Mining and Metallurgy Company, AngloGold Ashanti, Polyus, Zijin Mining Group, Gold Fields, Kinross Gold and Northern Star Resources. These are producers. Lannister Mining is an exploration company at a much earlier stage.
Who is the world's largest gold mining company?
Newmont ranks first on the Investing News Network list of top 10 gold-mining companies. According to that list, Newmont holds a 38.5 percent interest in Nevada Gold Mines through a joint venture with majority owner Barrick. Rankings shift with production and acquisitions, so check current company reports for the latest picture.
Who owns the richest gold mine in America?
The largest US gold operation by output is Nevada Gold Mines, owned 61.5 percent by Barrick and 38.5 percent by Newmont, according to Investing News Network. Farmonaut, citing Barrick, reports that the four Nevada Gold Mines sites produced about 2.59 million ounces in 2025, roughly half of US output.
What US state has the most gold in the ground?
Nevada leads US gold production. Farmonaut, citing the USGS, reports that Nevada produced about 64% of US gold in 2025 and Alaska about 22%. Production is not the same as gold in the ground, but it shows where large deposits are mined today. Montana, home to Basin Gulch, has a gold history dating to 1852.
Are there mineral exploration companies in the USA?
Yes. Many mineral exploration companies work on US properties, in states including Nevada, Alaska and Montana. Lannister Mining is one of them, focused on the Basin Gulch gold-silver property in Montana. Directories such as Mining News North list exploration and geological service companies active in Alaska and the North.
How much do mineral exploration companies in Canada spend?
Natural Resources Canada reports preliminary data showing Canadian exploration expenditures rose 4% in 2025 to $4.4 billion, after $4.2 billion in 2024. Junior exploration companies spent $2.11 billion in 2024, essentially unchanged from $2.12 billion in 2023. Lannister Mining has its office in Vancouver but explores in Montana.

Montana and the gold market

Why explore for gold in Montana?
Montana is known as the Treasure State for its mineral wealth and mining history, and mining still plays an active role in its economy. The first gold discovery in the Montana territory occurred in 1852 at Gold Creek, near present-day Garrison. Silver, copper, nickel and platinum have since been discovered and mined there.
What is the Philipsburg Mining District?
It is a historic mining district in west-central Montana, around the town of Philipsburg. Lannister Mining describes Basin Gulch as located in the heart of the district, which the company says led the original US silver boom in the late 1800s. Philipsburg is also the starting point for road access to the property.
What was the gold price high in 2026?
Investing News Network reports gold reached US$5,589.38 on January 28, 2026, and Sprott cites an all-time high of $5,595 per ounce in January. Gold then fell, with Sprott reporting a 25.3% peak-to-trough drawdown from March 2 through July 16, 2026, before gold miners rallied about 30% in August.
Where is Lannister Mining's office?
The company lists its office at 1500 - 1055 West Georgia Street, Vancouver, BC, Canada V6E 4N7. The Basin Gulch property itself is in west-central Montana, about one hour by road from Butte. It is common for exploration companies to keep a head office in a financial center while working a project elsewhere.
