Deposit Type, Target Concept, Potential Size


Nekash is a gold rich porphyry copper target located in the Idaho-Montana porphyry belt. This belt is known for hosting porphyry deposits such as Butte Montana, CUMO, and Thompson Falls. Nekash is a blind target identified by anomalous copper and gold mineralization in prospects at the surface, stockwork veining, and calc-silicate alteration of the sedimentary rocks above the target zone. The company holds 70 federal mining claims over the property. The exploration plan is to collect a soil grid over the project, along with ground magnetic data that will be sent for inversion processing to develop drill targets. 

Summary


The Nekash copper project is located in Lemhi County, Idaho and is covered by 70 federal unpatented mining claims that were staked in 2024 by the Company. Historically the United States Bureau of Mines (USBM) evaluated various prospects on the property (Mayerle and Close, 1993), collecting geochemical samples and evaluating the geology. Their conclusion was that the two areas of porphyry style mineralization (Figure 9) may represent a blind porphyry deposit. They also concluded that a mineralized bed (stratigraphic horizon) that is exposed on the project warrants further exploration work. The Company believes that the porphyry style mineralization visible on two areas of the property and the mineralized bed, along with various other historic copper gold prospects may represent the surface expression of a blind porphyry copper deposit under the project.

Nekash is located in the Dahlonega Creek Formation, Mesoproterozoic quartzite, carbonate, and pelitic sedimentary rocks that are likely correlative with the Yellowjacket formation that hosts the majority of the stratabound cobalt mineralization found in Lemhi County, Idaho. The project lies along a zone of continental-scale shearing known as the Trans-Challis shear zone in Idaho and the Great Falls Shear zone in Montana that runs from SW Idaho to NE Montana. This zone is broadly defined by the occurrence of porphyry deposits. 

To the east, just across the border in Montana the Mesoproterozoic sediments give way to Tertiary-Cretaceous intrusive rocks. This intrusive suite almost certainly extends under the sedimentary rocks of the Nekash Project and is the source of the porphyry mineralization seen on the property. 

Nekash is hosted in a wedge of Mesoproterozoic sedimentary rocks of the Dahlonega Creek Formation that is underlain by Tertiary-Cretacous igneous rocks that intruded the area. These sediments are comprised of quartzite beds and calc-silicate beds primarily, with the latter likely a hydrothermal (skarn) alteration of what were originally carbonate beds. 

Mineralization in the areas with known porphyry alteration are in the form of both small stockwork veins that contain copper minerals, and quartz-sericite veins up to 6 feet wide with both pyrite and copper minerals. USBM sampling in these areas returned rock chips up to 6.6% Cu and 0.6 g/t Au. 

USBM Sampling at the mineralized bed (Kopr Mine) included a 21’ chip sample across a portion of the mineralized bed that returned 3.2% Cu, 0.9 g/t Au, and 25 g/t Ag. The bed is approximately 30’ thick where it is exposed in an old dozer cut. 

The Company collected 8 rock chips from the mineralized bed and areas of porphyry alteration. Results have not been received yet.
