Lima, Peru, March 28, 2013 (GLOBE NEWSWIRE) -- The Graystone Company(OTCQB: GYST) announced today that the Company's mining crew hascompleted setting up the new equipment and has begun using it forthe company's mining operations. The Company has uploaded photos onits Facebook page of the new equipment. Previously, the Company used a 12-foot sluice box that did notcontain riffles. The Company now is using a 30-foot sluicebox with Hungarian riffles. The Company's CEO, while in Perulast week, tested the tailings from our mining operations and foundfine gold in the tailings. Even though the Company has onlybeen using the new equipment for few days, the new tailings containa significant less amount of fine gold. Therefore, theCompany expects the amount of gold recovered will significantlyincrease now that the new equipment has been set up and is in use. The company will be adding additional photos from Peru alongwith videos on its Facebook page. We have received questions on how a sluice box works in goldmining. Essentially a sluice box is like a long tray which isopen at both ends. Most will have riffles, spaced evenly along thelength of the sluice perpendicular to the length of the sluice.Riffles cause small barriers to the water flow which creates eddiesin the water, giving the heavier material (black sand and gold) achance to drop to the bottom, behind the riffles. The longer thebox is and the better the quality of riffles correlates to theamount of gold that will be recovered.The reason that riffles work is twofold. First, there is an eddycreated behind each riffle, causing a temporary lull in the waterflow. The material that is flowing is in a liquid state. Thiscauses the heavier material (a/k/a heavies) to be at the verybottom of the flow. As the flow passes over a riffle, the heavieswill fall to the bottom behind a riffle. Second, the rifflesare spaced a couple of inches apart, and act as a series of smalldams, stopping the creep of the heavy material down the sluice.Without them, there would be a slow, but sure creep of gold out theend of the sluice.Normally most of the trapped gold will be behind the first coupleof riffles. This is because the heavies fall fast. Small flour goldmay extend several riffles further, and, hopefully, the last fewriffles have zero gold. The longer the sluice box is the more goldthe Company can capture. Typically there will be a 3/16thinch layer of material called miner's moss or carpet laying on thesurface of the sluice. It is a loose weave matt with lots of airspace. It traps and holds the smallest gold particles. On top ofthat can be a layer of expanded metal. This creates a criss-crosspattern of spaces, each with their own eddies. Then the riffles,that resemble a ladder, with each riffle a rung, when swung up, islowered into place and latched down.Each time you clean up, you raise the riffles, and remove the moss.You then wash down the sluice, wash out the moss, and put it backtogether.
