Aurbis Resources (CSE:AURR) says interpretation of geophysical data from its Ecru Gold Project in Nevada, US, has identified 10 targets for follow-up ahead of planned drilling later this year.
In July, the company completed a series of geophysical surveys at the 100%-owned property in Lander County, including a high-resolution magnetic survey over a newly identified hornfels alteration zone.
Interpretation of the magnetic data, supplemented by an existing gravity survey dataset, identified what Aurbis interprets as the Ecru intrusion in the central-western portion of the project.
The work also mapped the Northern Nevada Rift (NNR), which bisects the northeastern portion of the property.
Ecru lies at the intersection of three major geological structures associated with producing mines and development projects operated by Nevada Gold Mines (NGM).
As part of its exploration model, Aurbis is using NGM‘s nearby Robertson gold deposit as an analogue, where gold mineralisation is associated with hornfels/skarn and reduced intrusion-related settings.
The company says Ecru’s magnetic and gravity data indicate prospective buried hornfels zones along the margins of an interpreted intrusion, where heat transfer and structural pathways may have created favourable conditions for fluid flow and potential gold mineralisation.
The geophysical interpretation identified 10 areas interpreted as potential hornfels targets, which the company has grouped into three distinct types.
According to Aurbis, the combined datasets are also helping to define structures across Ecru, an important control on the exploration model given the relationship between structures and mineralisation observed at Robertson.
The company says the new interpretation has refined Ecru’s structural framework, including the scale, timing, and sequence of geological features, providing additional information for drill target generation ahead of planned drilling in late 2026.
“It is rare for geophysical data to so closely represent the physical, geological, and geochemical characteristics of a mineralisation style as we have seen at Ecru,” CEO Johan Lambrechts says.
“The intrusion is clearly visible in the data, and the increased density and magnetic characteristics expected of a mineralised zone are also present in the areas interpreted as hornfels.”
Looking ahead, Aurbis says it will initially focus on the Robertson-style intrusion-related gold targets.
The company will also continue evaluating targets associated with the NNR, which it says hosts a series of high-grade gold mines along strike to the north and south of Ecru.
Aurbis Resources is a gold explorer committed to systematic, data-driven discovery on ground with genuine geological merit.
