MAS Gold Corp announced additional positive results from preliminary metallurgical testwork completed on composited drill core material from the North Lake gold deposit located in the La Ronge Gold Belt of northeastern Saskatchewan. Mr Ron Netolitzky President and CEO of MAS Gold said "Although preliminary, the flotation gold recovery test results of better than 89% for the five tested sub-samples are very encouraging. These test results, combined with our earlier reported, positive cyanidation recovery test results, provides MAS Gold with a number of potential options for high gold recoveries from our North Lake property. Other positives include the BWI of T2.9 kWh/tonne, which reflects a medium hardness for the tested material, and total sulphur recovery to flotation concentrates of better than 93%, which suggests a limited potential for acid generation from the flotation tails".

Two sets of flotation tests were carried out on 2.0 kg sub-samples taken from the Master Composite. The first set (on sub-samples F-1 and F-2) tested the effect of grind size on gold recovery. The second set (on sub-samples F-3 through F-5) tested the effect of different reagent concentrations at a grind size targeting P80 125 pm (i.e. approximately the mid-point of the grind sizes for sub-samples F-1 and F-2).

A standard bulk flowsheet was employed in both cases, along with the following reagent suite
PAX (potassium amyl xanthate, a strong sulphide collector and an effective reagent for free gold recovery)
F-160-10 at 60 g/t (a strong, glycol-based frother used to ensure a stable froth)
