(TSXV: BHS) (the \"Company\" or \"Bayhorse\") has conducted extensive metallurgical work on a high grade sample from the Bayhorse Silver Mine, Oregon, USA., to establish a smelter concentrate for submission to select smelters for off-take pricing.A select 62.52 kg sample was milled and subjected to a known standard open circuit batch concentration process whereby a gravity concentrate is made and the middling gravity recovery would normally be resent through the milling circuit for further gravity upgrading. The subsequent mineralized tails are subjected to further gravity recovery and flotation to create an overall concentrate. On a weighted average basis, the first gravity concentrate yielded 9.171.5 kg that contained 19,512.9 g/t (570.30 oz/short ton) silver, 25.9% copper, 14% antimony, 12.4% zinc, 4.1% arsenic, and 6.2% silica. The partial results are tabulated below.Concentrate Weight gramsAg g/tonne Ag ozshort tonCu % Zn % Sb % As %Si %Weighted Avg 9,171.50 19,512.00 570.30 25.90 12.40 14.17 *4.10 6.2 (*Antimony is over limit by the assay method and should be viewed as approximate)While normally the middlings of 7.63 kg would be recirculated through the mill to produce additional gravity concentrate, in this instance the middlings are already of direct shipping grade of 10,443 g/t (313.97 oz/st) and are added directly to the gravity concentrate without further concentration. Silver recovery was 27.8% to gravity concentrate, rising to 40.6% when middlings are added to give an average grade of 15,528 g/t (439.7 oz/t). The table gravity tails of 45.7 kg, (73.1%) containing 59.4% of the silver, also of direct shipping grade, were subjected to additional recovery analysis using a Falcon Concentrator plus flotation. Three passes of the Falcon Concentrator gave similar results of 11,646 g/t (340.4 oz/t) indicating more passes would recover more silver. This gave a preliminary silver recovery of 67.9%.A separate sample of the high grade table tailings was subjected to flotation at starvation reagent levels. 45.3% of the residual silver was recovered at a grade of 13,450 g/t (393.4 oz/t), which is equivalent to a combined gravity and flotation silver recovery of 67.2%. The resultant concentrate an...
