GOLDEN STATE MINING LIMITED Golden State Mining Limited provided details of results and planned follow up activities from the first pass regional geochemical program recently conducted at its 100%-held Paynes Find lithium project in the Murchison Region of Western Australia. The Company has received and interpreted ultrafine soil assay results from its first phase regional geochemical sampling at its Paynes Find project, 683 soil samples were collected by independent contractors for analysis of the ultrafine fraction (<2m) over a number of regional grids on 400m centres along 800m spaced, east-west orientated lines. These grids were located over areas interpreted to encompass relatively shallow regolith cover considered amenable to this sampling methodology and best suited to deliver any potential basement response.
The total sampling area completed to date represents only 14.4% of the granted tenure at the Paynes Find project. These selective areas do not include higher priority structural targets which are based on aeromagnetic signatures with interpreted deeper cover where drill testing will be required. A lithium pegmatite targeting exercise was completed by an independent geochemist using various statistical grouping and leveling methods of the multi-element assay data.
Statistical grouping used a weighted sum methodology, calculated from known economic and selected supporting elements for LCT pegmatite mineralisation styles. The levelling methods mitigated the effects of any assay batch variation and regolith control. The resultant >90th percentile sample population has highlighted areas showing anomalous lithium (Li) values which are supported by other pathfinder elements including beryllium (Be), caesium (Cs), niobium (Nb), rubidium (Rb), tin (Sn) & tantalum (Ta).
The coherent occurrences of elevated Li-Rb-Cs together is considered particularly significant as a regional indicator for the presence of LCT pegmatite mineralisation. These group 1 alkali elements have a similar chemistry in surficial environments and are known to occur together in a pegmatite related setting. This process has identified 29 initial areas of interest which have been ranked in order of priority for follow up work.
The highest priority area for soil infill is located on the western side of the central tenement area within a 6.7km2 area of contiguous samples anomalous in lithium with supporting elements including Cs, Rb & Ta along a 6km north-north-easterly trend. The highest lithium assay recorded at this location was 217ppm in sample PFX0669 along with 16.5ppm Cs, and 217ppm Rb. The second priority area (Figure 4) is located on the north-eastern end of the northern tenement over a 7.7 km2 area within an approximate 2.6km x 3.6km zone of contiguous lithium- anomalous samples supported by similar pathfinder elements.
The highest lithium assay recorded at this location was 158ppm in sample PFX0578 along with 23.9ppm Cs, and 157ppm Rb. The remaining priority infill soil targets consist of clusters of lower priority areas of interest which will be completed later in the year. Data analysis and target generation for base metal potential is ongoing.
