Five Star Diamonds trades under the symbol STAR on TSXV, with around 6.5 m shares out, giving it a market cap under 3 m. It recently got an infusion of capital from Turquoise Capital Corp -- a capital pool for which Five Star Diamonds became its 'Qualifying' investment. In effect, the Turquoise Capital Corp contributed the funds needed to advance the Catalao project and then renamed itself Five Star Diamonds, after the former company's name. It was a way to get money and a listing on the TSX Venture exchange.
Given the low market cap, Five Star has very promising diamond exploration properties, as discussed on the company website fivestardiamonds.net The Catalao project is the one being fast tracked toward production, if all goes as planned.
Note that the diamonds are in Kimberlite pipes near the surface, and preliminary results have found high quality diamond samples.
