TinOne Resources Inc. announced it has sampled highly elevated lithium grades from its 100%-owned 9,600 hectare Aberfoyle Project located in the tier-one mining jurisdiction of Tasmania, Australia. During reconnaissance exploration programs for tin across the Aberfoyle project, TinOne geologists sampled mica (greisen) altered granite, where ten samples returned highly elevated lithium values of 0.1% Li2O or above with a maximum of 0.57% Li2O. Greisen alteration of the type sampled at Aberfoyle is a typical alteration style associated with many tin deposits globally and is also associated with certain large scale lithium deposits, where the mica alteration minerals are lithium-bearing.

Lithium grades (expressed as Li2O) in these mica-hosted deposits are typically in the range 0.3-0.7% Li2O. The elevated lithium samples at Aberfoyle come from three separate areas over an area of more than 8 km by 4 km, suggesting that the lithium occurrences are not isolated and may be part of a previously unrecognised lithium camp. The main area of elevated lithium sampled to date covers the historic Guinea Pig and Dead Pig small-scale tin mining prospects with five of the seven rock samples collected over an area of approximately 600 x 250 metres returned values over 0.1% Li2O and up to 0.57% Li2O.

Approximately 2 km north of the Guinea Pig prospect, two samples in the Ockle Creek area returned 0.10% and 0.12% Li2O, respectively. In addition, another sample collected at the Tasmania Creek prospect to the northeast returned 0.22% Li2O and one sample a further 1 km north returned 0.1% Li2O. Samples that returned 0.1% or more Li2O were sent for umpire analysis at SGS Townsville, Australia and returned values consistent with the original ALS results (Table 1), thereby confirming the significance and validity of the original laboratory results.

Selected higher grade samples were also analysed by X-ray diffraction12 (XRD) at the Minerals Resources Tasmania laboratory and confirmed the presence of substantial quantities of the mica zinnwaldite {KLiFeAl(AlSi3)O10(OH,F)2}, which is globally the most important mica-host for hard rock lithium deposits.
