Electronic Multishot - Grade Control

It is vitally important that all Grade Control holes are positioned accurately as this is the last opportunity prior to mining to pin point the ore body.

Can you afford to dilute your ore body?

Our Electronic Multishot is utilised to survey at 5m intervals providing a true and accurate hole path.

Usually a series of holes are drilled from one bench then we use ore called in for survey prior to back filling or prior to blast hole drilling.

At Downhole Surveys we understand the mining process and are mindful that Grade Control is an integral part of the day to day life of an operating mine.

Our aim is to complete the downhole survey with minimal interruption to the mining process.

The Electronic Multishot is our survey instrument of choice due to its ability to survey many holes in one session, reliably and accurately. Our productivity is typically 3000m per shift.
