Triumph comprises two EPMs (EPM 18486 and EPM 19343), which are located in the Northern New England Orogen, 50km south of the city of Gladstone. It is easily accessible from the sealed Gladstone-Monto Road. Historical production from the area produced approximately 20,000oz of gold from shallow sources between 1879 and 1941.

The 15km² gold system is 90% concealed beneath shallow sediment cover (less than 5m thickness), which presents a unique opportunity to generate and drill test targets on this previously unrecognised large gold system. Systematic exploration over the outcropping areas has led to the discovery of high-grade gold mineralisation in drilling on six prospects: Bald Hill West, Bald Hill East, New Constitution, Advance, Super Hans and Big Hans.

The project has already demonstrated high-grade gold mineralisation in both discrete vein and shear hosted deposits. Previous owners focussed on the collection of quality geochemical and geophysical data to vector toward the large-scale systems. Previous drilling intersected significant shallow, high-grade gold at Bald Hill, New Constitution, Super Hans, Big Hans and Advance. Rockchips to 255 g/t Au also provided encouragement at the Bonneville Prospect. Significant drill intersections from each of the prospects include:
The project geology is dominated by the Norton Tonalite, a late Permian aged intrusion that has intruded through the Carboniferous sediments of the Wandilla Formation. The tonalite has been displaced by the late-stage, north-west oriented Norton Fault. Approximately 1.8 km of apparent sinistral, strike-slip displacement along the Norton Fault appears to have occurred post-mineralisation. The implications of this inferred late-stage deformation are significant when determining the likelihood of offset lode positions. An example of this that the mineralisation identified at Super Hans is interpreted to be the offset extension of the Bald Hill mineralisation. Further interpretation of the magnetics indicates that the Bald Hill system extends for approximately 3 km on the east of the Norton Fault and the Super Hans system extends for a further 3 km to the west of the fault. The interpretation is supported by regular gold intersections greater than 1 g/t Au in wide spaced drilling.

The delineated shallow high-grade prospects are manifest in the project magnetics as zones of magnetic depletion. A revised structural interpretation has been completed over the project area and integrated with the geochemical and other geophysical information. This work has already generated new high-priority targets at Brigham-Young and Galena.
The Bald Hill prospect is well defined by drilling over a strike length of 300m. Bald Hill shows continuity of economic grades and thicknesses along strike and down-dip and is open in all directions (Figure 6).

Sunshine Gold has a dual strategy for Triumph of assessing the open-pit potential while testing for deeper, large-scale mineralisation. Specifically, Sunshine Gold plans to:
