Sant Tolgoi Project: Latest Developments
Xanadu Mines Ltd (ASX: XAM, TSX: XAM) is advancing work at the Sant Tolgoi Copper-Nickel Project, a new effort in an under-explored, mineral-rich belt. The team is focused on magmatic intrusion-related copper-nickel systems and is running field programs to gather the data needed to zero in on high-grade sulphide mineralisation—the kind of ore that can move a project forward.
Exploration Program Overview
Field exploration is well underway at Sant Tolgoi. This phase marks the start of detailed work across district-scale magmatic targets. To build a robust geological picture, Xanadu Mines is combining surface geological mapping with geochemical sampling, step by step, to understand how this system hangs together on the ground.
Mapping and Geophysics: Recent Progress
The team has completed acquisition of high-resolution magnetic and gravity datasets, along with Controlled Source Audio-frequency Magnetotellurics (CSAMT). These data are now being modelled to refine targets. Early outcomes are encouraging: multiple shallow copper-nickel sulphide targets have been outlined over several kilometres, guiding where to focus next.
Leadership Perspective
Dr. Andrew Stewart, Xanadu’s VP of Exploration, noted his enthusiasm for the ongoing program at Sant Tolgoi. He described it as a greenfields opportunity with the potential to define a new magmatic Cu-Ni district within an under-explored mineral province. According to Dr. Stewart, extensive surface mapping has already highlighted copper-oxide mineralisation at surface—evidence that supports the exploration strategy now in motion.
Project Footprint
The Sant Tolgoi Project covers two Exploration Licences—XV-17774 (Oyut) and XV-21887 (Sant Tolgoi)—together spanning more than 40km2. Within this area, there are multiple advanced exploration targets that could deliver meaningful copper and nickel discoveries if the current model holds up.
Geological Setting
Sant Tolgoi lies in the Zavkhan region on the western extension of the deep-seated Khangai fault systems. This structural corridor hosts several large intrusions, a strong signal when you’re searching for copper and nickel sources. Historical drilling in the broader area has already pointed to early signs of multiple copper-nickel systems, which adds weight to the current exploration thesis.
Agreement Highlights
Xanadu Mines has signed a binding agreement with STSM that enables the company to earn up to an 80% interest across the two licences. The structure reflects a clear, staged path and underscores Xanadu’s commitment to the project and its potential.
How the Farm-in Works
Stage 1 allows Xanadu to earn a 51% interest by investing USD $1,000,000 in exploration over two years. On completion, that stake secures a meaningful position in the project and sets up the next decision point.
What Comes Next
After reaching a 51% interest, Xanadu and STSM can form a Joint Venture (JV). A JV framework would align both parties on planning, resourcing, and day-to-day management, keeping decision-making coordinated as work scales.
Path to 80%: Continued Investment
If STSM elects not to contribute its pro-rata funding, Xanadu can increase its ownership. By sole funding an additional USD $10 million in exploration, it can move toward an 80% interest—an option that would give it greater control over future development.
About Xanadu Mines
Xanadu Mines is a publicly listed exploration company focused on large-scale copper-gold discoveries in Mongolia. The company offers exposure to significant projects, including the Kharmagtai deposit through a joint venture with Zijin Mining Group. Its exploration programs continue to draw attention from investors following progress across the portfolio.
Frequently Asked Questions
What is Sant Tolgoi aiming to discover?
The program is targeting magmatic intrusion-related copper-nickel systems and aims to pinpoint high-grade sulphide mineralisation within a broad intrusive complex.
What fieldwork has Xanadu completed so far?
Xanadu has carried out geological mapping and geochemical sampling and completed high-resolution magnetic, gravity, and CSAMT data acquisition, which is now being modelled.
Have any targets been identified yet?
Yes. Multiple shallow copper-nickel sulphide targets extending over several kilometres have been outlined based on the new geophysical datasets.
How does the agreement with STSM work?
It’s a staged farm-in. Stage 1 lets Xanadu earn a 51% interest by investing USD $1,000,000 in exploration over two years, with a path to a potential 80% interest through further investment.
What could happen after Xanadu reaches 51%?
Upon reaching a 51% interest, Xanadu and STSM can form a Joint Venture. If STSM doesn’t fund its pro-rata share, Xanadu may sole fund an additional USD $10 million to increase its interest toward 80%.
