OK465:
There is also a Silver ILS 16R for certain approved operators that has much lower mins. It was explained to me that if certain aircraft had good engine out performance and could do the MAP over the terrain after descending to lower mins, the Silver ILS was approved.
Interesting, too, that the FAA version of the approach has some differences, notably a 9000' PT alt and 8500* at TAKLE (*7400 when authorized by ATC).
