Ewan Edward Project (Truscott 100%)
Lyall - Hera Node
(SELA27731,EL25497, EL25577, EL26221 (all 100%))
Truscott's Ewan Edward Project is located 20 kilometres east of Tennant Creek which contains the primary exploration nodes Lyall and Hera (Figure 5) and covers two interpreted trends of strongly mineralised lodes.
Field observations have delineated an area of outcrop within SELA27731 that demonstrate structural features that characterise other important nodes for economic mineralisation. A vein array (multiple veins) and a central zone of alteration further enhanced the prospectivity of the location.

The nodes defined at Peko, Westminster and Lyall are interpreted as zones of dilation and coincide with the development of ironstone outcrop within gravity lows. Dilational settings are where alteration and potential high grade gold mineralisation are likely to be concentrated.
At Lyall, an ironstone outcrop pattern of over a kilometre strike length has been identified that demonstrates the geometry and structure consistent with a zone of dilation. Rotary Air Blast (RAB) drilling at Lyall confirmed geological concepts and will assist in the planning for a deeper RC drilling program. The iron oxide unit returned highly anomalous bismuth and copper (maximum values 3m @ 634g/t Bi, 46ppm Cu) on the northern limb of the anticline and the mineralisation remains open to the west. Mineralisation throughout the field is commonly zoned with bismuth and copper enrichment occurring above significant concentrations of gold mineralisation. Further drilling is planned to extend the anomalous zone identified at Lyall.
The interpreted nodes within the "Southern Shear" that include Juno and Hera are also expected to be associated with gravity lows, however the gravity footprints are likely to be different due to the influence of the apparent movement along this corridor. A similar structural setting to that identified at Lyall is interpreted at Hera as seen by the similarities in the detailed ground gravity image that cover the two nodes (Figure 5). It is envisaged that further drilling at Lyall will provide a better understanding of the controls on potential mineralisation at Hera.
