Rock Tech Lithium Inc. has announced the first batch of assay results from the field sampling programme recently completed at its 100%-owned Georgia Lake lithium property in the Thunder Bay Mining District of Northwest Ontario, Canada.
Phase I of the field program targeted the Parole Lake region, an area of the Georgia Lake lithium property that hosts at least six lithium-bearing pegmatites. The No. 4 pegmatite was the site of drilling conducted this past spring and hosts an historic resource estimate. During this field programme, the No. 1, No. 2, No. 3 and No. 5 pegmatite dykes were located and georeferenced. While no outcrop was found related to the No. 6 pegmatite, historic trenches were located and georeferenced. A total of six (6) grab samples were collected from the No. 1 and No. 3 pegmatite dykes, the results of which are presented in the following table:
Martin Stephan, Chief Executive Officer of Rock Tech, commented:
“The Parole Lake region is one of the key growth areas of the Georgia Lake lithium property and the sample results confirm that follow up trenching and drilling is warranted. The geo-referencing of these pegmatites has provided us with modern coordinates and proper locations, increasing the effectiveness of follow up trenching and drilling. Sampling these pegmatites will provide valuable insights regarding the lithium content of these pegmatites as assays were not reported for all historic drill holes completed in the 1950s and 1960s.”
Parole Lake Region
The Parole Lake region of the Georgia Lake lithium property hosts at least six lithium-bearing pegmatites. One of them, the Parole Lake No. 4, was the site of recent drilling and channelling and has an historic resource estimate of 1.5 million t grading 1.30% Li2O (Pye, 1965); however, the historical estimate does not use the categories set out in sections 1.2 and 1.3 of NI 43-101 and a Qualified Person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. As a result, the Parole Lake pegmatite is not included in Rock Tech’s NI 43-101 resource estimate.
The results from the recent channel programme confirmed the presence of high-grade lithium mineralisation on surface with a sample showing an average grade of 1.89% Li2O over 4.22 m, including 2.69% Li2O over 1.03 m. The recently completed drill programme, with one intersection averaging 1.53% Li2O over 11.65 m, confirmed lithium mineralisation at depth, provided a better understanding of the geometry of the lithium-bearing pegmatite, and will greatly enhance the efficacy of future drill programs. Additional drilling is required before estimation of true width in core intersections can be determined. For complete details of the channel sample and drill results, please see the news releases dated 3 May and 29 June 2017, respectively.
All samples were analysed by Actlabs, an ISO 9001:2008 certified analytical laboratory located in Geraldton, Ontario.
The field programme was carried out by Pleson Geoscience, an exploration consulting company dedicated to providing its clients with experienced personnel and efficient services. The company’s focus is on low-impact, high resolution data collection from grass-roots prospecting to preliminary economic evaluations.
