FMR Resources Drills First-Ever Holes at Chile Copper-Gold Target
Key Takeaways
- FMR Resources has commenced its first-ever drill program at La Lorena just five months after acquiring the project, with a minimum 2,000m diamond drilling program targeting the La Martuca prospect in central Chile.
- Surface rock chip samples at La Martuca returned copper grades of up to 5.32% Cu, providing the high-grade geological basis for prioritising this prospect as the opening drill target.
- IP geophysical surveying has identified multiple chargeability anomalies at depth, with one feature spatially associated with the known surface mineralisation, giving the program defined subsurface targets beyond the artisanal workings.
- Assay results are expected 6–8 weeks after completion of the first drillhole, with the full program running 10–12 weeks, establishing a clear near-term newsflow timeline for shareholders.
- La Lorena is one of three active Chilean exploration projects for FMR, with the Esperanza prospect and Llahuin JV also advancing in parallel, creating a multi-catalyst pipeline across the coming months.
Drill bit hits ground at La Lorena for the first time
FMR Resources (ASX: FMR) has commenced its first-ever drill program at the La Martuca prospect within the La Lorena Project in central Chile, just five months after securing the project. The move marks a significant shift from data-gathering to active drill testing of a copper-gold target that has already returned high-grade surface results.
The initial program is planned for a minimum of +2,000m of diamond drilling over 10 to 12 weeks, commencing at La Martuca. Assay results are expected 6 to 8 weeks after completion of the first drillhole.

What the drill program is targeting
The program has been designed with three objectives in mind. First, to test the continuity of mineralisation between the historical artisanal mine levels at La Martuca. Second, to identify extensions to the known mineralised structures along strike. Third, to investigate IP chargeability and magnetic features defined through 3D modelling.
Together, these targets give the program both near-surface and depth-oriented components, and the combination of historical workings and modern geophysics provides a strong basis for the initial drill design.
High-grade surface results set the scene
La Martuca was selected as the starting point based on previously reported rock chip sampling that returned high-grade copper at surface. The three headline results from those prior announcements are:
- Sample 26LMR00030: 5.32% Cu
- Sample 26LMR00019: 3.93% Cu
- Sample 26LMR00018: 2.19% Cu
These samples were collected from around the artisanal workings and were previously reported by FMR in its announcement dated 26 May 2026. They are cited here as context for why La Martuca was prioritised as the opening target.

IP chargeability adds depth to the story
Beneath the surface, IP (induced polarisation) geophysical surveying has identified multiple chargeability features at La Martuca. One of these chargeability features is spatially related to the known mineralisation at surface.
Drilling will test the geological source of the multiple IP features and their relationship to known mineralisation along strike. However, it is important to note the announcement’s own caveat: the spatial association between chargeability and known mineralisation supports drill targeting but does not establish the presence, grade, or continuity of mineralisation within the modelled features. Drilling will determine the nature of the chargeable material and test the geological interpretation.
Understanding copper-gold porphyry exploration in Chile
To appreciate why this drill program matters, it helps to understand the geological setting and what FMR is actually looking for.
Porphyry copper-gold systems are large, bulk-tonnage mineral deposits formed by ancient volcanic and magmatic activity. They are among the most economically significant deposit types in the world, and Chile hosts some of the largest examples on earth, including Los Pelambres. Epithermal systems are shallower, structurally controlled deposits that often form alongside or above porphyry systems and can host very high-grade near-surface mineralisation.
The La Lorena Project sits within an area underlain by Eocene-aged volcanic and intrusive rocks, as interpreted from regional mapping and published age determinations by Chile’s national geological survey, SERNAGEOMIN. These younger units overlie older Cretaceous basement, defining what the source describes as a favourable magmatic and structural setting for porphyry and epithermal mineralisation.
Critically, the project lies within a regionally significant Trans-Lithospheric Fault (TLF) corridor, as described by Rivera y Yañez (2019). This large-scale structural architecture is interpreted to control magma ascent, intrusive plumbing, and metallogenic fertility in central Chile. The same corridor links major mineralised districts including Los Pelambres and Punitaqui, and extends through the broader La Lorena-Los Warbos area.
From a practical standpoint, La Lorena is well-positioned logistically. The project is located in the Coquimbo Region, approximately 380km north of Santiago, at elevations of 1,600m to 2,500m above sea level. The area is serviced by regional access roads, is close to the electricity grid, and lies approximately 20km from the nearest sealed airstrip. Ports at Coquimbo (approximately 200km by road to the northwest) and Los Vilos (approximately 170km by road to the southwest) provide export infrastructure. The Coquimbo Region is an established mining district with access to experienced personnel, services, and suppliers. That combination of geological prospectivity and infrastructure access reduces the practical barriers typically associated with early-stage exploration in more remote jurisdictions.

What comes next for FMR shareholders
With drilling now underway, the near-term newsflow pipeline for FMR is starting to take shape. The next steps, as outlined in the announcement, are:
- Complete the initial +2,000m La Lorena drilling program, commencing at the La Martuca prospect
- Receive and integrate assay results, expected 6 to 8 weeks after completion of the first drillhole
- Complete integrated assessment of the Esperanza prospect datasets, including initial drillhole design
- Progressively refine and rank additional targets identified across the La Lorena Project
- Continue multi-project exploration across La Lorena, Los Warbos, and the Llahuin JV
Managing Director Oliver Kiddie framed the significance of the drill commencement in two statements:
Oliver Kiddie, Managing Director
“Drilling of the first-ever drillhole at the La Lorena Project marks another important milestone for FMR only 5 months after securing the Project. A +2,000m program has been designed across La Lorena, beginning at the La Martuca prospect, where we will test a series of compelling targets including mineralisation below artisanal workings and extensions beyond the workings, along with IP chargeability and magnetic features defined by 3D modelling.”
Oliver Kiddie, Managing Director
“The next few months are incredibly exciting for FMR shareholders as we continue to gather datasets and drill test multiple highly-ranked targets across La Lorena, Los Warbos, and the Llahuin JV. We look forward to updating the market with our progress as we continue our exploration journey, with a clear aim of a company-making discovery.”
What the next steps illustrate is that La Martuca is only the first chapter. FMR holds three active Chilean projects at various stages of exploration, and the commencement of drilling at La Lorena is the opening catalyst in what the company is positioning as a sequence of upcoming newsflow. For shareholders, the combination of assay results, additional target ranking at Esperanza, and ongoing activity at Los Warbos and the Llahuin JV means the months ahead are expected to deliver a steady stream of material updates.
This upcoming pipeline includes the parallel advancement of the Llahuin porphyry system, where previous campaigns have successfully outlined broad zones of mineralisation while vectoring toward a higher-grade core.
