Technical Overview of the Clarkdon Gold Property
Focus Xplore PLC (AIM: FOX) ("Focus Xplore" or the "Company") provides a technical review and details of the Phase 1 exploration programme underway for the Clarkdon Gold Property ("Clarkdon" or the "Property"), situated in northwestern Ontario, Canada, following its recent acquisition by the Company.
Key Highlights
Geological Summary
The 18 km² Clarkdon property is located in northwestern Ontario, on the Sturgeon Lake greenstone belt, part of the Superior craton, the world's largest Archaean craton. The belt is about 2.7 billion years old and hosts historical zinc-copper volcanogenic massive sulphide (VMS) mines. Recent seismic and magnetotelluric geophysical surveys suggest the belt was thrust into place along a major fault zone, the South Sturgeon Fault Zone, which crosses the south of the property1, and forms the boundary between the Winnipeg River and Western Wabigoon Terrane. Such terrane boundaries, defined by major fault zones in this part of Ontario are commonly associated with gold2.
Locally, the property is underlain mainly by metamorphosed volcanic rocks, with bands of schist and gabbro, bordered to the south by granite and cut by faulting3 (see Figure 1). Historical drilling in 1971 intersected copper-bearing sulphides at the Moss Lake occurrence in the north of the property. Linear magnetic trends in legacy airborne data, linked to mapped alteration and faults4, have never been tested for gold and offer early-stage, grassroots targets for gold mineralisation.
The tenure is in good standing until 15 February 2027 and carries an annual minimum spend commitment of C$34,400 (approximately £19,000).

Figure 1: Clarkdon Property Geology, Targets and Proposed Sampling
Previous Exploration on the Clarkdon Property
Clarkdon has minimal historical exploration. A six-hole, 534 ft (162.8 m) diamond drilling programme, using 7/8 in (22 mm) core, was completed in the north of the property in 1971 by Scurry-Rainbow Oil Limited5 6 (detailed below), and is recorded in the Ontario Mineral Inventory as a historical intercept of 29 ft (8.84 m) grading 0.43% Cu and 14 g/t Ag.
Elsewhere, the property has received only geological mapping in the late 1960s4 and airborne geophysical surveys and interpretation3 in 1970; no further work is reported to have been carried out on the property.
Exploration Model for Clarkdon
The exploration model for Clarkdon centres on targeting gold mineralisation associated with the South Sturgeon Fault Zone (SSFZ), which is a major, deep-rooted regional structure that may act as a pathway for gold-bearing fluids1, similar to the highly prolific Porcupine-Destor and Cadillac-Larder Lake fault corridors in the Abitibi Gold District. The SSFZ is interpreted to extend to depths of 20–40 km in the crust, which may have allowed potentially auriferous, deep-seated fluids to be driven upwards during major geological events1. Such fault systems can host significant gold mineralisation where they intersect or interact with smaller fault networks, competent intrusive rocks, volcanic units, and banded iron formations 7 8, and therefore represent attractive targets for gold exploration.
The property has two main target areas:
These areas are shown, alongside the general property geology, on Figure 1.
South Sturgeon Fault Zone Potential
In the southern sector of the claim package, airborne electromagnetic (AEM) and magnetic geophysical surveys have delineated prominent conductive and magnetic horizons10.
Historical drilling11 within the SSFZ, approximately 600 m east of the property, intersected disseminated to massive pyrrhotite-pyrite in sheared felsic to intermediate volcanic rocks and schists adjacent to a granitic contact. Sulphide-bearing horizons are displaced by northwest-striking cross-faults, and the host rocks include silicified shear zones with deformed quartz veining – very limited assaying for gold took place in these units, and thus the majority of the sulphide units were untested. On Clarkdon, legacy Very Low Frequency (VLF) trends suggest the presence of faulting and structure associated with these potentially sulphide units.
This combination of structural intersections and contrasting lithologies is geologically favourable for gold mineralisation7, especially in proximity to a major, crustal-scale fault system.
Central Structural & Magnetic Trend
The central part of the property is characterised by linear magnetic trends in legacy airborne geophysics that have not been tested for gold. These lineaments occur close to mapped alteration and secondary structural zones, and one linear feature weakens in the property centre. Such weakening may reflect magnetite destruction by hydrothermal alteration, a recognised vector towards structurally controlled gold mineralisation7, although other causes cannot be excluded. Historical mapping records carbonate-bearing alteration and disseminated to massive sulphides in this area4. Calc-silicate and carbonate assemblages are commonly associated with hydrothermal fluid migration in orogenic gold systems12, making this area a target for gold exploration.
Regionally, similar structural trends host auriferous quartz veins and shear-hosted mineralisation13, including up to 6.17 g/t Au and 1,000 ppm Co; however, equivalent targets at Clarkdon have not yet been tested. Results from neighbouring areas are not necessarily indicative of mineralisation on the Property.
Moss Lake Base Metal Occurrence
In the north of the property, historical diamond drilling by Scurry-Rainbow Oil Limited in 1971 5 6 comprised six shallow holes totalling 534 ft (162.8 m) of 7/8 in (22 mm) core. The holes intersected amphibolitic greenstone, meta-gabbro and gabbro with minor pyrite, trace chalcopyrite, local pyrrhotite, quartz veining and calcite stringers. The Moss Lake occurrence was subsequently recorded in the Ontario Mineral Inventory (OMI14), which lists a historical intercept of 29 ft (8.84 m) grading 0.43% Cu and 0.41 oz/t Ag (about 14 g/t) within amphibolitic greenstone. Moss Lake is interpreted as primary, pre-metamorphic mineralisation that is not considered related to any later gold mineralisation on the property, and it is not currently a key target area.
Regional Context & Infrastructure
The property lies within an active exploration district. Claims held by Midex Resources Ltd border it immediately to the east (Figure 1), and Glencore Canada holds significant mineral tenure about 7 km along strike to the east. Forestry access roads and a former railway line, now converted to a track, cross the tenure, giving good surface access from Highway 599, which runs north from the Trans-Canada Highway (Highway 17) at Ignace.
Phase 1 Exploration Programme
Focus Xplore has allocated £23,000 from the recent £0.5m placing to fund a Phase 1 field exploration programme at Clarkdon, in October 2026. The costs of this programme will allow the Company to meet the minimum expenditure requirement.
The planned exploration programme consists systematic geochemical soil sampling and geological prospecting over two main areas;

|
Mineral occurrence |
A documented location where mineralisation has been observed; it does not imply economic size or grade. |
|
Mineralisation |
A concentration of metals or minerals of potential economic interest within a body of rock. Mineralisation does not imply that an economic deposit exists. |
|
Orogenic gold |
