Fortitude
North

AN EXCITING GREENFIELDS DISCOVERY WITH ACCESS TO EXISTING INFRASTRUCTURE

Fortitude North Gold is a highly prospective gold exploration asset within Matsa Resources’ broader Lake Carey Gold Project. This greenfields discovery has quickly emerged as a priority growth opportunity, attributable to encouraging exploration outcomes.

With consistently high-grade drill results, the potential for additional parallel lode systems and openness at strike and depth, Matsa Resources plans to advance drilling and technical work to better define the system and advance it toward a clear resource pathway.

OVERVIEW OF THE DISCOVERY

Fortitude North was first discovered by Matsa Resources following an aircore drilling program in 2018. As it stands, the asset is comprised of a 1.7km long mineralised zone that remains open along strike and depth.

Mineralisation is structurally controlled within interpreted dextral slip dilational jog and data offers evidence of a long-lived system with multiple gold forming stages. Subsequently, this suggests that a large system may be present.

Based on what Matsa Resources currently knows, the size of the Fortitude North anomaly is larger than that of the Fortitude Gold Mine.

A GEM IN THE LAKE CAREY GOLD PROJECT CROWN

An asset within the Lake Carey Project, Fortitude North is positioned in the north eastern Goldfields region, in Western Australia. Established mining townships Kalgoorlie and Laverton are located 244km north east and ~70km north, respectively.

In terms of its position within the Lake Carey Project footprint, Fortitude North is located only 6km north of Matsa’s Fortitude gold mine, in the gold endowed Kurnalpi terrain. This terrain is host to numerous world class gold deposits such as Sunrise Dam, Granny Smith and Wallaby.

CLASSIC EASTERN GOLDFIELDS CHARACTERISTICS SIGNAL POTENTIAL EXTRACTION BENEFITS

Fortitude North displays the makings of a classic Eastern Goldfields deposit. Its gold mineralogy is structurally controlled and suggests the presence of stacked lodes.

Stacked gold lodes can be described as multiple, vertically parallel layers of gold mineralisation that occur within a deposit. They form when mineralised fluids infiltrate a series of parallel fractures or fault zones in the host rock, resulting in multiple distinct zones of gold mineralisation. 

This structural makeup signals potential benefits to extraction, as it means that multiple gold zones may be accessed from the same mining infrastructure.

There are many major gold deposits in the Eastern Goldfields that feature stacked lode systems, some of the most notable including parts of the Golden Mile at Kalgoorlie and elements of the St Ives gold camp near Kambalda.

OPERATIONAL HIGHLIGHTS

Open Along Strike

Drilling completed at Fortitude North to date has intersected mineralisation along the horizontal plane but has not yet found the outer boundaries of the deposit. This signals resource expansion potential and offers greater assurance in explorative drilling than attempting to locate mineralisation in unexplored ground.

A High-Grade Asset

Fortitude North has consistently delivered high-grade results across various drilling campaigns. Some significant returns include:

  • 8m @ 9.0g/t Au from 283m [3rd lode] and 10m @ 6.5g/t Au from 65.5m Upper lode
  • 22m @ 9.2g/t Au from 327m 3rd lode
  • 25m @ 3.3g/t Au from 147m Upper lode
  • 14m @ 3.4g/t Au from 113m [Upper lode] and 35m @ 3.0g/t Au from 150m 2nd lode
  • 19m @ 3.8g/t Au from 100m Upper lode
  • 11m @ 3.8g/t Au from 108m Upper lode
  • 11m @ 4.2g/t Au from 130m Upper lode
  • 12m @ 3.4g/t Au from 143m Upper lode
  • 47m @ 2.55g/t Au from 42m 4th lode
  • 4.0m @ 13.6g/t Au from 79m Upper lode
  • 3.4m @ 12.3g/t Au from 64m 4th lode
  • 10.3m @ 3.5g/t Au from 124.6m 3rd lode

The thickness and grade of early intercepts in the second lode provides confidence that additional drilling could define a mineralised structure of substance. Matsa envisages drilling up plunge to the south, where this lode structure is expected to be intersected at shallower depths.

Exploration Target Defined

Based on soil sampling and wireframing of 130 holes (AC, RC and DD) drilled between 2018 and 2025, an exploration target has been defined ranging between:

10Mt @ 2g/t Au for 643koz, and; 23Mt @ 2.5g/t Au for 1.85Moz

This target size is based on a mineralised geometry of multiple northerly plunging stacked lode structures, each of approximately 800m strike extent, up to 10-15m thick and 250m wide, each capable of hosting 3.5 – 4mt of mineralisation.

Matsa has commenced an initial 10,000m diamond drilling campaign to test the modelled multiple stocked lode geometry of Fortitude North. Based on a successful initial drilling campaign, it is anticipated a further 10,000m of infill drilling will be required to provide adequate drilling to define a maiden resource which will commence later in 2026.
