Highlights

  • Siguiri Basin concessions cover major regional shear structures with extensive artisanal workings and geochemical anomalies.
  • Initial drilling confirmed thick shallow oxide gold mineralisation in Birimian sedimentary sequences and quartz-vein arrays.
  • Northern Territory's Fenton project is testing deep magnetic anomalies for large-scale shear-hosted gold systems.
  • DES shares closed at $0.120, a market capitalisation of $33.21 million, after a 33.33% twelve-month decline.

Striking into one of West Africa's most prolific gold provinces, Desoto Resources(ASX:DES) is running systematic RC and diamond drilling campaigns along the Siguiri Basin trend in Guinea — the same geological corridor that hosts AngloGold Ashanti's flagship gold operation — while advancing geophysics at Fenton in the Northern Territory.

Strategic Pivot to the Siguiri Basin

Historically focused on the Pine Creek Orogen in the Northern Territory, Desoto executed a major acquisition to secure exploration concessions within the world-class Siguiri Basin in Guinea, West Africa. The basin is globally renowned for multi-million-ounce orogenic gold deposits, including AngloGold Ashanti's flagship Siguiri gold mine.

Shares were priced at $0.120 on 2 October 2026, establishing a market capitalisation of $33.21 million. The stock has declined 33.33% over the trailing twelve months as financial markets exercised discipline toward micro-cap exploration juniors.

Multi-Target Drilling Programme Results

The focal catalyst throughout 2026 was the launch and expansion of multi-target reverse circulation and diamond drilling programmes across Siguiri tenure. Desoto's concessions cover major regional shear structures with extensive artisanal workings and pronounced surface geochemical anomalies.

Initial drilling across priority targets confirmed thick intervals of shallow oxide gold mineralisation hosted in Birimian sedimentary sequences and quartz-vein arrays. The company's Australian exploration at Fenton simultaneously advanced geophysics and structural modeling, assessing deep magnetic anomalies concealed beneath Cambrian limestone cover.

Gold Economics and Treasury Discipline

Gold is the primary economic driver for Desoto. In an environment of historic high Australian Dollar gold prices, discovering economic open-pit oxide resources in the Siguiri Basin provides rapid commercial monetisation optionality.

Management has focused expenditures on direct drill metres across the most prospective targets, practicing prudent treasury management. The company's Fenton project in the Northern Territory provides complementary discovery optionality within a domestic Australian jurisdiction.

West African Operations and Key Risks

Desoto does not generate commercial revenues and relies on equity placements to finance aggressive drilling, exposing shareholders to potential capital dilution. Operating across international borders in West Africa introduces sovereign regulatory considerations and logistical lead times.

Seasonal wet-weather constraints across Guinea affect drilling schedules, while assay turnaround delays and commodity price volatility remain additional investment variables.
