Exploration upside
About two-thirds of the Basin Gulch Property is still unexplored, and the known mineralization is open.
Lannister Mining reports that Basin Gulch gold-silver mineralization is open at depth, along strike and untested regionally, with multiple high priority targets near the historic resource. Combined with year-round access from Philipsburg, that leaves substantial room for new drilling beyond the more than 320 historical holes.
Last updated: Published by Lannister Mining
Roughly two-thirds of the 1,107-hectare Basin Gulch Property is unexplored, according to Lannister Mining. The historical drilling concentrated on the known mineralized area, mainly on patented land, leaving much of the surrounding unpatented ground for future mapping, sampling and drilling.
Definition
Mineralization is open when drilling has not yet found its edge. Open at depth means the deepest holes still ended in mineralized rock or did not test below it. Open along strike means the zone has not been closed off in the direction it runs across the ground.
Lannister Mining reports Basin Gulch mineralization as open in multiple directions and at depth, along strike and untested regionally. For an explorer, open mineralization is where expansion drilling usually starts, because each step out can test whether the zone continues. Results can extend a zone or close it off; neither is known until it is drilled.
By the numbers

Comparison
| Criterion | Explored area | Unexplored area |
|---|---|---|
| Share of property | About one-third | About two-thirds |
| Land type | Primarily patented land | Includes surrounding unpatented claims |
| Existing data | More than 320 historical drill holes and trenches | Multiple high priority targets identified |
| Planned work | Confirmation and expansion drilling | Drilling of additional mineralized target areas |
Step by step
A typical sequence for testing open ground, in line with the work Lannister Mining describes for Basin Gulch.
Use the 320+ historical holes and trenches to define where zones remain open.
Drill beyond known intercepts at depth and along strike.
Map and sample unexplored ground to rank high priority targets.
Test additional mineralized target areas within the property.

About two-thirds of the Basin Gulch Property is still unexplored, according to Lannister Mining. The company reports multiple high priority targets near the historic resource, and most of the 1,107-hectare land package remains available for future mapping, sampling and drilling. That unexplored ground is the main source of the exploration upside the company describes.
Open in the FAQ: How much of Basin Gulch is unexplored?Yes. Lannister Mining reports that gold-silver mineralization at Basin Gulch is open in multiple directions and at depth, open along strike, and untested regionally. Open mineralization means past drilling did not find its limits, so further drilling could extend it. Future drilling is planned to concentrate on additional mineralized target areas within the property.
Open in the FAQ: Is the Basin Gulch mineralization still open?Lannister Mining reports multiple high priority targets near the historic resource and says the mineralization is open at depth, along strike and untested regionally. About two-thirds of the property is still unexplored. Future drilling is planned to concentrate on additional mineralized target areas within the property, alongside confirmation drilling of historical intercepts.
Open in the FAQ: What targets remain to be tested at Basin Gulch?Future drilling at Basin Gulch will concentrate on additional mineralized target areas within the property, according to Lannister Mining. The company also plans expansion and confirmation drilling around historical drill intercepts, since the mineralization is open at depth and along strike. Those results, together with historical data, are intended to feed a maiden mineral resource estimate.
Open in the FAQ: Where will future Basin Gulch drilling focus?Basin Gulch offers a partner a historical dataset of more than 320 drill holes, near-surface oxide-hosted gold-silver mineralization open in multiple directions, and a consolidated land package of 11 patented and 53 unpatented claims. With about two-thirds of the property unexplored, Lannister Mining reports multiple high priority targets and room for new discovery work.
