Solstice Minerals Limited Announces Significant Gold Anomalies Confirmed by Infill Soil Sampling At the Nippon Licence, Ponton Project
Solstice Minerals announced very encouraging gold and multi-element assay results have been received for a recently undertaken soil sampling program over the Nippon License (Nippon or the License), E39/2184. The Nippon License is located approximately 200km northeast of Kalgoorlie, Western Australia, within the Duketon Domain of the Burtville Terrane at the southeast margin of the Yilgarn Craton. Initial reconnaissance UltraFine fraction (UFF) surface sampling was conducted over the license in 2021. The initial sampling targeted discrete northern and central aeromagnetic anomalies, interpreted to have been either ineffectively tested or untested by historical drilling. The sampling was conducted at 200m x 400m grid spacing with interpretation of the results defining several subtle but coherent gold-in-soil anomalies which warranted infill sampling. Further UFF sampling was conducted in April 2022, with infill sampling reducing the grid spacing to 100m x 200m in areas of interest and extension of the sample grid where gold anomalism remained open. An extensive 1.7km x 0.5km zone of significant gold anomalism (Nelson Prospect) up to 19.3ppb has been identified in the north of the License and correlates closely with the northern aeromagnetic anomaly. The Nelson Prospect gold anomaly is broadly supported by multi-element assay data including bismuth, copper, molybdenum, and lead. A second significant 1.8km x 0.8km zone of gold anomalism (Trafalgar Prospect), up to 14.8ppb, has also been identified 6km to the south of Nelson Prospect along the central aeromagnetic anomaly. The Trafalgar Prospect gold anomaly is strongly supported by elevated silver, copper and lead multi-element anomalism. The nature of the coarse aeolian sand sample medium and dunal landform setting are expected to typically generate only very subtle gold-in-soil anomalies, with gold assay values >4x the background value considered highly anomalous and extremely encouraging from a regional targeting perspective. Follow-up work for Nippon will include detailed geological and structural interpretation of airborne magnetic and radiometric data, landform mapping and planning for an air core drill program to determine thickness of the post-Archaean cover and test for gold anomalism in the basement rock. Nippon License (E39/2184), Ponton Project: The Nippon License is located approximately 200km northeast of Kalgoorlie, Western Australia, with good access via the Kurnalpi-Pinjin and Tropicana Gold Mine Roads. The Mulga Tank ultramafic intrusive-related nickel deposit, which is currently being explored by Western Mines Group, is approximately 25km to the west and the Mulga Rocks sediment-hosted uranium deposit, being developed by Vimy Resources, is located about 30km east of the License. The Tropicana Gold Mine is located approximately 130km further to the east of Nippon. In terms of regional geology, the license lies within the Duketon Domain of the Burtville Terrane at the southeast margin of the Archaean Yilgarn Craton where the craton adjoins the Proterozoic Officer Basin. Most of the license area is covered by recent stable aeolian sand dunes, which can overly Tertiary alluvial, fluvial, and lacustrine sands, silts, clays and carbonaceous sediments including lignite. The thickness of the Tertiary sediments can be up to 100m deep in palaeochannels. Permian Paterson Formation may or may not be present overlying the Archaean basement. Basement is mostly comprised of granite and lesser greenstone lithologies, with historical drilling intersecting both mafic and ultramafic lithologies. Aeromagnetic Targeting: Initial targeting utilized publicly available 400m line-spaced regional data and defined two linear, positive aeromagnetic anomalies (the northern and central aeromagnetic anomalies) suggestive of greenstone belt or ultramafic intrusive rocks. In late 2021, the Company initiated a regional- scale aeromagnetic survey over Solstice Minerals' licenses in order to reduce the overall line- spacing of the Company's proprietary aeromagnetic data set in the Eastern Goldfields to 100m (refer Prospectus). The Nippon License was covered during this airborne survey and preliminary interpretation of the newly acquired higher resolution data confirmed and better defined the magnetic anomalies, as well as identifying interpreted regional and subsidiary fault structures. The northern anomaly is a 1.3km x 0.8km relatively linear positive aeromagnetic anomaly, oriented north-northwest south-southeast (which is slightly oblique to the regional northwest fabric), with several regional-scale interpreted fault structures converging near the anomaly. The northern aeromagnetic anomaly is coincident with the Nelson Prospect (discussed below). The central anomaly is a relatively large positive, linear aeromagnetic anomaly with a long axis of 9km and between 0.5 to 1km in width. The anomaly is oriented northwest-southeast and is cross- cut by several interpreted northeast-southwest Proterozoic dykes. The Trafalgar, Victory and Swordsman Prospects are located along the anomaly from northwest to southeast, respectively.
