Pan American Energy has completed a nine‑day field program at its Tharsis rare earth project, collecting geological mapping, magnetic susceptibility readings, and lake bathymetry. The program was to determine first drill targets at Squalus Lake in Canada’s Northwest Territories. The company said the integrated datasets will be consolidated into a 3D workspace to refine a geological model and direct collar placement for an initial campaign.
The work was carried out in late September and marks a move from reconnaissance toward drill planning. It is a modest step, but it tightens technical risk ahead of procurement for drilling services and seasonal logistics.
The campaign end date and reported scope are firm. The disclosure notes Tharsis remains at the exploration stage and prospective for rare earths and niobium, not yet at resource definition, according to the company’s 28 October filing. The results are positioned to guide near‑term decisions on access, equipment, and budget.
Data Confirms Carbonatite Potential
Interpretation from the fieldwork highlights a magnetic low at the centre of the Squalus Lake alkaline complex that is consistent with carbonatite phases typically associated with rare earth mineralisation, while a surrounding magnetic ring appears less prospective syenitic material. Crews documented contrasting susceptibility values at two outcrops, with the magnetic low averaging 0.46 by 10⁻⁶ SI and the magnetic high ring averaging 55 by 10⁻⁶ SI, which supports the emerging conceptual model for target ranking.
The bathymetric survey captured roughly 17,500 depth points on 100 metre east to west lines, enabling a detailed lake‑bottom surface for fusing with surface geology and magnetic readings.
As integration proceeds, the company expects to identify drill holes beneath the lake where geology and geophysics converge. “Our team has completed an exceptional amount of work in a short field window,” said CEO Adrian Lamoureux.
Financing Positions Near‑Term Exploration
Field execution follows a C$3 million capital raise on 14 October 2025, comprising a C$2 million listed issuer financing exemption, or LIFE, offering and a C$1 million concurrent private placement, which the company has earmarked for exploration and working capital.
The LIFE structure, available under National Instrument 45‑106, allowed the charity flow‑through and non‑flow‑through shares to be immediately free trading in Canada, broadening participation beyond traditional accredited channels and easing follow-on placements.
With funding in place, Pan American can advance procurement for drill contractors, camp services, and aviation support once permits and Indigenous engagement milestones are confirmed.
In an earlier operational update, management underscored the stepwise approach to de‑risking target definition. “This program is an important step forward for the Tharsis Project,” said Adrian Lamoureux. (globenewswire.com)
Permitting and Indigenous Considerations
Alongside technical work, Pan American reported an archaeological field survey supported by a local Indigenous community member, aligning exploration activities with territorial heritage requirements and building on a prior desktop assessment. These measures matter in the Northwest Territories, where successful drill mobilisations often hinge on early cultural screening, predictable access plans, and clarity around water and land use approvals.
The company’s next steps include thin‑section and QEMSCAN analyses, preparation of a preliminary geological map, and integration of subsurface topography with mapped lithologies to finalise drill collar priorities. If the model holds, initial holes will test the magnetic low beneath Squalus Lake where carbonatite phases are inferred.
Delivery now depends on timely permit coordination, contractor availability, and a tight winter window. Overall, Pan American’s data‑light but methodical campaign reduces subsurface uncertainty at low cost and readies the project for a targeted first pass of drilling. They still need to translate geophysical coherence into mineralised intercepts, then into defensible resources that can justify further capital.
For now, investors and territorial stakeholders have a clearer map, a funded runway, and a pragmatic sequence to test the core of the system. The next meaningful catalyst would be a drill permit and a contracted rig, followed by assays that validate the carbonatite thesis. The bar is straightforward. Early success would accelerate options on scale and partners.
