FMR Resources (ASX: FMR) is preparing to ramp up drilling at the La Martuca prospect, part of the La Lorena project in central Chile, after induced polarisation (IP) studies defined a set of high-priority targets.

The company has completed preliminary three-dimensional (3D) inversion modelling, integrating IP data from five finished survey lines. The modelling has refined the interpreted geometry of several chargeability features — including one spatially associated with the known mineralised structures at La Martuca — and now forms the basis for first-pass drill planning. IP is a widely used geophysical technique in mineral exploration that measures how well subsurface materials hold an electrical charge, helping to map disseminated sulphide mineralisation that may accompany copper and gold systems — a particularly relevant method in Chile, one of the world's largest copper-producing countries.

"Completion of the preliminary 3D IP inversion is a major step in advancing La Martuca towards drilling," Managing Director Oliver Kiddie said.

"The modelling has integrated the chargeability responses across the completed survey lines and provided a clearer basis for ranking and testing compelling drill targets.

"Importantly, one of the modelled chargeability features is spatially associated with the known mineralised structures at La Martuca. The first-pass drill plan is designed to test the continuity of those structures below surface, as well as several additional chargeability features identified at various depths by the modelling.

"In conjunction, IP surveying is continuing at Esperanza while snow cover clears at La Martuca. This allows us to systematically advance the La Lorena Project target pipeline while preparing to return to La Martuca to complete drilling preparations and remaining field work."

The initial drill program is planned for a minimum of 2,000 metres over 10 to 12 weeks. A drill contract has been awarded to Big Bear Drilling, with mobilisation scheduled within four weeks.

While access at La Martuca remains restricted by snow cover, IP surveying continues at Esperanza, advancing the La Lorena project target pipeline. The remaining La Martuca IP survey line, L101, along with drill pad preparation, will be completed once the snow clears and safe access is re-established. For a junior explorer of FMR's size, progressing multiple targets in parallel during seasonal access constraints is a common approach to keeping exploration programs on schedule in the high-altitude Andean environment.

FMR shares were up 0.61% at 41.3¢, giving the company a market capitalisation of $27.49 million.
