I think Cupric has shown the best, most cost effective method of mining the contact is underground mining - as it does dip away at some angle, is not all that thick (10m think - you aint going to dig down 100m to mine 10, a 10:1 strip will ruin economics) and also lends itself to not having to backfill / paste fill which is quite expensive.
