Looks like the buyout price is about 220 million dollars. Mag's main holding is a portion of Fresnillo which amounts to about 120 million ounces of inferred silver equivalent. Also as far as i can tell, Mag holds $60 million in cash, so the buyout is really more like $160 million which amounts to about $1.33 per ounce silver equiv. Their grades are about the same as ECU but their widths are better at the main vein running 3 to 4 meters. At this point Mag's portion of the resource is only 1/2 to 1/10th of ECU's depending on if potential is counted. The mine overall is great and substantial with about 270 million ounces silver equiv, but still probably smaller than ECU's, and Mag only owns 44% of it.
If ECU doubles its MI+I to 400 million ounces than $1.33 per ounce silver equivalent would give us a market cap of 533 million dollars or about $2.20 per share. A year or two ago, the silver juniors and majors were priced at about $3 to $4 per ounce silver. At the current $9 COMEX silver and 50 cent zinc, nobody is profitable so something has to give here.
