SS1 secures water supply for exploration and development at US silver project

Our US silver Investment Sun Silver (ASX: SS1 | OTCQX: SSLVF) just secured groundwater rights at its Silver Project in Nevada, USA.

SS1’s project has a 539M ounce silver equivalent JORC resource - the largest pre-production primary silver resource in the USA and on the ASX.

SS1 has four rigs turning at Maverick, feeding a maiden Scoping Study targeted for late 2026 into early 2027.

Today SS1 confirmed that local authorities have granted it 50 acre-feet per year (AFY) of groundwater, around 62 million litres of water annually.

This gives SS1 more scope for exploration and development activities, and removes a limitation where water availability had been holding back exploration:

Separate to this, SS1 has also lodged an application for 2,000 AFY (around 2,480 million litres per year), aimed at future processing activities at Maverick.

SS1’s scoping study is due by “late 2026”, “early 2027”

In the background, SS1 still has four rigs turning at Maverick, feeding a maiden Scoping Study due Q4 2026.

SS1 recently updated its timeline - the maiden Scoping Study is now targeted for late 2026 into early 2027, with a Pre Feasibility Study to follow in 2027, alongside further resource upgrades:

What's next for SS1?

🔄 Drill results from the current program

With four rigs turning, we should see a steady flow of results.

The infill drilling for the resource upgrade and the one we are looking out for the most - the extensional drilling to the north-west of the existing resource:

🔲 Scoping study - Q4 2026/Q1 2027

The maiden scoping study will pull together the resource, met testwork, and mine planning into an economic picture.

This is the one we think could change the way the market views SS1’s projects (finally giving it some project economics context)

Recently SS1 confirmed Ausenco (a global engineering company) will be used as lead engineering consultant who will help run studies for the Scoping Study/Preliminary Economic Assessment due by the end of the year.

🔲 Maybe a maiden antimony resource?

We have written in the past about how SS1’s deposit may also host a giant antimony resource to go with the silver.

IF a maiden antimony resource can be defined, we think it would be a game changer for SS1’s deposit AND could open up US government funding pathways for developing its project.
