Summit Minerals Limited reported on three significant soil and rock geochemistry anomalies, including Munga Creek, at the Company's 100% owned Windfall Antimony Project near Kempsey in NSW. Each north-south trending multi-element anomaly lies within an inferred east-west corridor and corresponds with a topographic high. The interpreted corridor extends west through the Pinnacle and Tooroka Camps.

Rock chips up to 8.56% Sb and 1.05% Sb in ultrafine soils were returned from first-pass exploration across the historical workings. The central and most significant anomaly corresponds with the historical Munga Creek Mine, where the mineralisation remains open south of the workings. The positive results across Munga Creek reinforce the prospectivity and pave the way for follow-up exploration activities, including drilling (subject to access).

Munga Work Program Rock chips and conventional soils were collected during general prospecting of the historical workings and neighbouring environments. Summit moved to standardise the exploration by utilising ultrafine soils on a 50m x 50m regular grid under the pretext of designing a drilling campaign beneath the historical Munga Creek workings. Twelve (12) rock chips and 93 ultrafine soils were assayed.

Ultrafine soils replicated the conventional soils, which are not being reported. Three north-south trending multi-element anomalies lie within an inferred east-west corridor and correspond with adjacent topographic highs. Their distribution must be understood because their extent could be an artefact of the local regolith development or en echelon veining associated with axial faulting within east-west anticlines.

Recognition of the latter promotes the opportunity for vein stacking within mineralised positions. Further opportunities are hitherto unrecognised because regolith development has impacted surface geochemistry, obscuring any underlying mineralisation, and/or the inferred east-west control has been overlooked in preference for the more apparent north-south control and mineralised repetitions potentially lie between all three historic mining camps (Munga Creek, Pinnacles and Tooroka) and west of the Tooroka Camp. The Munga Creek Mine is a historical antimony mine in New South Wales, Australia.

It is situated near Hillgrove, approximately 60 kilometres east of Armidale. The Munga Creek Mine operated intermittently from the late 1800s until the mid-1970s. It primarily produced antimony, a metal used in various industrial applications.

Antimony was extracted from underground mining operations at the site. The mine's production history includes periods of significant activity, especially during World War I and II, when antimony was highly demanded for military purposes. However, due to fluctuations in global markets and changing economic conditions, the mine eventually closed in the early 1970s.
