Surge Battery Metals Inc. (OTCQX: NILIF) said drilling has begun on the 2026/27 program at the Nevada North Lithium Project, after the project’s joint venture received approval from the U.S. Bureau of Land Management under the 2025 Exploration Plan of Operations permit. The project is owned by Nevada North Lithium, LLC, held 67.5 percent by Surge and 32.5 percent by Evolution Mining Limited, the Australian gold producer. Drilling is expected to run through the fall and into the 2027 season.

The program is described as up to 25 core holes totalling about 15,000 feet and up to 20 sonic holes totalling about 5,000 feet, testing the ground where the company plans to put waste rock storage, the processing plant and the access and haul roads, and refining the outline of the final pit. An allowance of up to ten reverse-circulation holes, about 5,000 feet, is set aside for rapid confirmation drilling and for installing piezometers. Two aquifer test wells, each paired with a monitoring hole, are to characterise the groundwater system, and a separate water supply well will serve the field camp. Core is to be logged and tested for geotechnical design, and bulk material collected for metallurgical test work and a pilot program ahead of a bankable feasibility study.

The resource itself was updated on June 30, 2026: a pit-constrained measured and indicated resource of 657.5 million tonnes grading 3,007 parts per million lithium, containing 10.5 million tonnes of lithium carbonate equivalent at a 1,250 parts per million cut-off. Greg Reimer, Surge’s president and chief executive, said in the release that with the pre-feasibility study nearing completion, the program is designed to fast-track the bankable study.

Reading the release

Almost none of this program is about finding lithium. Condemnation drilling is the opposite of exploration: its purpose is to prove there is no ore under the places where the mine will put its waste dumps, plant and roads, so that those facilities do not sterilise mineralisation. The sonic holes, piezometers and aquifer wells are about water and ground conditions, not grade. The release says as much in its own words, that the company is collecting the data its engineers need to design the mine plan. The news is a change of phase, from geology to engineering, on a deposit whose size is already on paper.

The number that matters most is not in the release. A pre-feasibility study is, per the chief executive, nearing completion; it will carry the first public capital cost, operating cost and process route for the project. The release gives no date for it. It does say that a pilot program precedes the bankable feasibility study, which means the process flowsheet for these lithium-bearing clays is still to be demonstrated at pilot scale. Clay-hosted lithium is processed differently from brine and from hard rock, and the metallurgical bulk sampling in this program feeds that pilot.

Water is the quiet item. Two aquifer test wells and a supply well are the first public step toward answering how much groundwater the mine would draw and what that does to the aquifer. In Nevada, the answer to that question shapes permitting. The release describes the testing and says nothing about water rights or the volumes a plant would require.

The release also does not say how the program is paid for between the two partners, or what Evolution Mining’s role is beyond its 32.5 percent. Evolution is described by its six gold mines in Australia and Canada; the release does not describe any lithium operating experience.

Questions worth asking

What will the pre-feasibility study say about capital cost and the process route, and when? “Nearing completion” is the only timing in the release, and the study is the document that converts a resource into an economic case.

How much water does the plan need, and who holds the rights? The aquifer tests in this program are the company’s first public work on the question.

What is Evolution Mining’s role beyond ownership? A gold producer holding a third of a lithium clay project is unusual; the release describes its mines, not its intentions.

What happens if condemnation drilling finds ore where the plant is meant to go? That would add resource and force a redesign of the site layout at the same time.

Key terms in this story

Condemnation drilling. Drilling under planned mine infrastructure to confirm that no economic mineralisation lies beneath it before the infrastructure is built on top.

Pit-constrained measured and indicated resource. A resource limited to what falls inside a conceptual open pit, reported in the two higher-confidence categories that can later support a mineral reserve. Inferred material, the lowest category, is excluded from that figure.

Parts per million lithium and lithium carbonate equivalent. Clay deposits are graded in parts per million of lithium metal. Lithium carbonate equivalent expresses that content as the tonnes of lithium carbonate it would make, the form in which most lithium is sold; the conversion factor is about 5.3.

Vibrating wire piezometer. A sensor lowered into a hole to measure groundwater pressure over time, used to see how the water table responds to pumping.

Bankable feasibility study. The engineering and economic study written to a standard that lenders will finance against. It follows a pre-feasibility study and typically requires pilot-scale proof of the process route.

What to watch

Fall 2026 into the 2027 season: drilling under way, per the company.

Pre-feasibility study: “nearing completion” per the chief executive; no date given.

Pilot program: to precede the bankable feasibility study; no date given.
