A little bit of hype. Anyone investing in a stock should do their DD. Most people buy on speculation expecting to make a fast buck. Playfair has alot more potential now than it had 8 months ago. Shareholders will see a buck again in due time.
Greyriver will give Playfair a positive cash flow to keep exploring for new tungsten deposits. Supply and demand, it's what keeps the price high and @ this point demand exceeds supply.
