South Orograde
Orogenic
Opportunity – Southern extent of a district-scale property, including expansion of the Erickson Ridge project in the Northern extent.
Overview: South Orogrande, situated within the southern portion of the Orogrande shear zone in the Elk City mining district, holds considerable promise for the discovery of a sizable gold-silver deposit. This stems from the favorable geological conditions of the project area and the results of exploration work conducted thus far.
The presence of significant areas of hydrothermal alteration, along with identifying gold mineralization both at surface and in historic lode mines, suggests the potential for substantial mineral deposits. These findings indicate that the project area has been subjected to hydrothermal activity, which is often associated with the formation of gold and silver deposits.
Given these indicators, further exploration efforts in South Orogrande could lead to the discovery of economically viable gold-silver mineralization. Continued mapping, sampling, and drilling programs may help delineate the extent and grade of the deposits, potentially unlocking significant value for Scout and its stakeholders.

Regional Geology
Erickson Ridge and South Orogrande are situated within the northern extension of the significant shear zone that contains the Stibnite gold deposit, which boasts over 7 million ounces of gold (Moz Au). This region is known for its geological richness and potential for further mineral exploration and development. The presence of the Stibnite deposit, a well-documented and extensive gold reserve, highlights the importance of the shear zone in influencing the mineralization patterns in the area. Both Erickson Ridge and South Orogrande are integral parts of this larger geological structure, suggesting that they may also possess considerable gold deposits and other valuable minerals, making them prime targets for mining activities and further geological studies.

Project Geology
The combination of Cretaceous granodiorite-hosted mineralization, Eocene dike swarms, and intersecting NS and NE shear zones within a long-lived structural zone presents a compelling geological setting for mineral exploration at South Orogrande.
Understanding the relationships between these features will be crucial for targeting exploration activities and identifying potential areas of economic mineralization.

Geochemistry
Presence of a 2 x 4 km gold in soil anomaly, with up to 0.82 g/t gold in soils and 15 g/t gold in rock chips. These findings indicate a widespread distribution of gold within the soil and rock samples, indicating the likelihood of substantial gold mineralization in the area.
The limited outcrop displaying strong gold-silver-arsenic-antimony correlation, comparable with the mineralization seen at the Stibnite deposit in Idaho, reinforces the prospectivity of the South Orogrande project. Stibnite, known for its significant gold and antimony deposits, serves as an analog for understanding the mineralization characteristics observed at South Orogrande.

Geophysics
A 3D-induced polarization (IP) survey has revealed a variety of geophysical anomalies within the surveyed area at the South Orogrande project. These anomalies include conductive, resistive, and chargeable targets, each indicating different geological features and potentially mineralized zones.
