Drilling, geology and how exploration works

How many drill holes have been completed at Basin Gulch?

More than 320 historical drill holes have been completed at Basin Gulch. These holes were drilled before Lannister Mining began its current work. The company plans to use this historical drilling together with new work programs as the basis for a future maiden mineral resource estimate.

What are the best historical drill results at Basin Gulch?

Highlight historical drill intersections published by Lannister Mining include 1.8 g/t gold over 162 meters from surface, 0.66 g/t gold over 326 meters from surface, 3.2 g/t gold over 72 meters from surface, 156 g/t gold over 3 meters, and 25 g/t gold over 14 meters. These are historical results, not a current resource.

What did the historical trenching at Basin Gulch show?

Lannister Mining publishes four historical trench highlights: 62 g/t gold and 32 g/t silver over 159 meters; 4 g/t gold and 23 g/t silver over 146 meters; 5 g/t gold and 54 g/t silver over 34 meters; and 25 g/t gold and 45 g/t silver over 61 meters. They are shown exactly as the company reports them.

What does oxide gold and silver mineralization mean?

Oxide mineralization is metal-bearing rock that has been weathered near the surface, so the original sulfide minerals have been altered to oxides. In general, oxide material near surface is easier to reach than deeper ore. At Basin Gulch, Lannister Mining describes the gold and silver as hosted in oxides and near surface.

What does g/t mean in drill results?

g/t means grams per tonne, the number of grams of metal in one metric tonne of rock. A result such as 1.8 g/t gold over 162 meters means the drill core averaged 1.8 grams of gold per tonne along a 162 meter length. Longer intervals at a given grade generally indicate more continuous mineralization.

Does Basin Gulch have a mineral resource estimate?

Not yet. Lannister Mining states that historical drilling and new work programs will be used in a future maiden mineral resource estimate. The company describes the property as having potential to host a significant maiden resource after expansion and confirmation drilling of historical drill intercepts. Until then, results should be treated as historical.

What is an NI 43-101 or S-K 1300 technical report?

NI 43-101 is the Canadian standard for public disclosure of mineral projects, and S-K 1300 is the equivalent US SEC rule. Both set requirements for how resources are estimated and reported by qualified persons. Lannister Mining states there is a clear market premium for compliant gold and silver ounces in the USA.

What drilling is planned next at Basin Gulch?

Lannister Mining states that future drilling will concentrate on additional mineralized target areas within the property, alongside confirmation and expansion drilling of historical intercepts. The company has not published a specific schedule on the pages this site draws from. For current program details, contact its investor relations team.

Philipsburg and Montana

What is the Philipsburg Mining District?

The Philipsburg Mining District, also listed as the Flint Creek Mining District, is a historic mining area around Philipsburg in Granite County, Montana. Lannister Mining describes it as the district that led the original US silver boom of the late 1800s. The Basin Gulch Property sits within it.

How much silver came out of the Philipsburg area?

The University of Montana writes that one Philipsburg-area mine was soon regarded as the greatest silver bonanza of its time and went on to produce $20 million in silver between 1885 and 1893. That figure comes from the university's history of Philipsburg and the Flint Creek Valley, not from Lannister Mining.

Why is Montana called the Treasure State?

Montana is known as the Treasure State because of its wealth of mineral reserves and a history built on mining. The first gold discovery in what was then the Montana territory occurred in 1852 at Gold Creek, near present-day Garrison. Silver, copper, nickel and platinum have since been discovered and mined in the state.

Is Montana a good place for gold exploration?

Lannister Mining considers Montana a safe jurisdiction for gold exploration, pointing to its long mining history and active mining industry. Montana is home to large scale producers still in operation today. The company also notes that US-based projects with compliant resources tend to trade at a premium to their peers.

How do you get to Basin Gulch from Philipsburg or Butte?

Basin Gulch has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, according to Lannister Mining. The property is about one hour from Butte. Year-round access matters for exploration because drilling and field crews can work through more of the calendar than at remote, seasonal sites.

Can I visit Philipsburg, Montana?

Yes, Philipsburg is a working town that welcomes visitors, and its own tourism site lists events and things to do. The Basin Gulch Property itself is an exploration site, so visits should be arranged through Lannister Mining rather than made unannounced. Use the company contact page to ask about site tours.

Exploration companies compared

What does a mineral exploration company do?

A mineral exploration company searches for and defines deposits of valuable minerals before any mine is built. Typical work includes mapping, sampling, trenching, drilling and, eventually, estimating a mineral resource. Lannister Mining is a mineral exploration company doing this work for gold and silver at Basin Gulch in Montana.

What is the difference between a gold exploration company and a gold mining company?

A gold exploration company finds and defines gold deposits; a gold mining company extracts and sells gold from an operating mine. Explorers usually have no production revenue and fund work through equity. Lannister Mining is an exploration company: it has historical drilling at Basin Gulch and is working toward a maiden resource estimate.

Is Lannister Mining a silver mining company?

Lannister Mining explores for both gold and silver, but it is an exploration company rather than a producing silver miner. Historical trench results at Basin Gulch report silver grades of 23 to 54 g/t alongside gold. The company describes its focus as gold and silver oxide mineralization near surface.

How do you compare gold exploration companies?

Common ways to compare gold exploration companies include jurisdiction, land package size, amount of historical drilling, grade and width of intercepts, whether a compliant resource exists, access and infrastructure, and the track record of the team. This site lays out those facts for Basin Gulch so readers can weigh it against other projects themselves.

How does an explorer like Lannister Mining differ from a large producer?

Large producers report output and revenue; explorers report drill results and targets. For scale, Lundin Mining reported producing about 33,000 ounces of gold and 77,000 tonnes of copper in its second quarter of 2026. Lannister Mining reports historical drill intercepts and land package facts instead, because Basin Gulch is still at the exploration stage.

What experience does the Lannister Mining team have?

Lannister Mining says many of its co-founders and senior executives were also behind K92 Mining, Fosterville South Exploration, Arena Minerals and Thesis Gold. CEO Jim Greig brings more than 25 years of experience advancing projects toward production, and CFO Kelvin Lee has more than 15 years of financial management with public companies.

Costs, timelines and getting started

How long does gold exploration take before a mine?

Gold exploration often takes many years before a mine decision, moving through drilling, resource estimation, technical studies and permitting. Timelines vary widely by project. Lannister Mining has not published a mine timeline for Basin Gulch; its stated next step is further exploration and resource development toward a maiden mineral resource estimate.

How much does an exploration drilling program cost?

Drilling costs vary with depth, terrain, access and drill type, so there is no single price. Year-round road access, like Basin Gulch has from Philipsburg, generally helps keep logistics simpler than at remote sites. Lannister Mining has not published a budget on the pages this site uses; ask its investor relations team for current figures.

How are gold exploration companies usually funded?

Most gold exploration companies fund their programs by selling shares, exercising warrants and options, or partnering with other companies. For example, Klondike Gold reported receiving $497,000 from the exercise of 3,500,000 warrants and stock options to the end of October 2026. Lannister Mining's own financing details are available from its investor relations team.

What is the difference between patented and unpatented claims?

In the United States, a patented mining claim is privately owned land, while an unpatented claim gives mineral rights on public land without owning the surface. Basin Gulch has 11 patented claims at its core, surrounded by 53 unpatented claims. Lannister Mining notes the property is primarily on patented land.

Risks and open questions

Can historical drill results be relied on?

Historical drill results are useful for targeting but are not the same as a current, compliant resource. That is why Lannister Mining plans confirmation drilling of historical intercepts before a maiden resource estimate. Readers should treat every historical number on this site as historical and confirm current status with the company.

What are the main risks in gold exploration?

The main risks in gold exploration are that drilling does not confirm expected grades or widths, that a resource proves smaller than hoped, and that costs, permits or metal prices change. These risks apply to every exploration project, including Basin Gulch, which does not yet have a compliant resource estimate.

What does open at depth and along strike mean?

Open at depth means drilling has not yet found the bottom of the mineralization; open along strike means its sideways extent along the trend has not been closed off. Lannister Mining says Basin Gulch mineralization is open in multiple directions and at depth, which leaves room to grow the known footprint.

Why is so much of Basin Gulch still unexplored?

Lannister Mining has not published a reason on the pages this site draws from. It states that two-thirds of the property is unexplored and untested regionally, and that future drilling will focus on additional target areas. Contact the company for the history of past work on the property.

Are the plans on this site guaranteed?

No. Plans for future drilling, a maiden resource estimate and resource development are intentions Lannister Mining has stated, not guarantees. Exploration results, financing and market conditions can all change plans. Nothing on this site is investment advice or an offer of securities.
