trading on a pe of 4

sorry forgot to change the heading to something more accurate.
PEM is trading on a current PE of 4. Forecast PE's for 2008 and 2009 are 4-5. Dividend yield is around 5%.
I cant find a cheaper stock on the entire bourse and thats why i bought these last week. Huntleys and UBS have current valuations around $3.50 using metals prices for Zn @ 0.90 and PB @ 0.70. All their current currency and metal hedges are in the money. PEM has around 170 miilion in cash. Results from Mt Oxide copper are imminent and the grades will be impressive. Visual copper intersects. Dont forget that some recent hits came back with +5% copper over 30m. Take away the cash on hand and the company has a current market cap around 250 million. Way way too cheap for the money they are making and forecast projects to come online. Mt Oxide will impress imho. Please do your own research.
