From the feasibility:

"the rhenium concentration in the 48 to 50% molybdenum concentrate is expected to be higher than 400 ppm."

"The average price was increased to over $3,000/lb in 2008 and 2009."

"The LOM average annual production is estimated to be approximately... 9,280 t/a of molybdenum concentrate"

Putting these numbers together means that the rhenium could contribute $24.6M/year in revenue. For comparison, the average revenue without the rhenium should be around $1227M per year. Keep in mind that the rhenium is difficult to process so the additional processing costs may cancel out the extra revenue.

"The recovery process for rhenium is complex and needs to be weighed against any potential profit."

"The potential additional value of rhenium in the molybdenum concentrate should be evaluated."

So it's something worth looking into, but it's not going to be a game changer for Schaft Creek.
