– Results suggest a 5t caustic fusion sample would be the appropriate minimum size to predict grade, by obtaining enough >1.18mm stones to understand the size vs. frequency distribution of the global diamond population.
The samples were taken at the same intervals as the first and they confirm that the different rock types have different diamond counts. The indicator minerals also demonstrate that the two main rock types, the volcanoclastic kimberlite and coherent kimberlite are different. While both have indicators equivalent to those found in the population of large diamonds found around the world, and diamond inclusion chromite,
only the coherent kimberlite has significant “G10” and eclogitic garnets with diamond inclusion chemistry.

The Sequoia caustic fusion results were processed through SRC laboratories of
Samples are placed in a kiln, heated to 5080C with caustic soda for 24 hours. The residue is hot poured through a 0.075mm sieve. The residue is then further chemically treated if required until just the refractory minerals remain including diamonds. The residue is sized by sieving and then the diamonds are selected by a mineralogist. Larger diamonds (>0.5mm) are described and weighed.

Cautionary Statement Regarding “Forward-Looking” Information
This news release contains “forward-looking statements” including but not limited to statements with respect to Arctic Star’s plans, the estimation of a mineral resource and the success of exploration activities. In this release it is not certain if the kimberlite discovered will be economic or not as this depends on many factors. Forward-looking statements, while based on management’s best estimates and assumptions, are subject to risks and uncertainties that may cause actual results to be materially different from those expressed or implied by such forward-looking statements. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Factors that could affect our plans include our potential inability to raise funds as intended, and in such event we may require all funds raised, if any, to be used for working capital rather than the intended uses as outlined. Accordingly, readers should not place unduereliance on forward‐looking statements.
