Hi everyone - have a look at this video from Oz Minerals form their new mine at Carrapateena. This is the mine that Hydrogen posted the video link of the box-cut yesterday.
It looks like it may be an exact blueprint of how Havieron mat develop over time. They have a similar situation where they have a higher grade section at the top of the deposit and a bigger lower grade section underneath. The decline has been sunk to the orebody and they are currently mining the top section using a sub-level caving method.
At the same time they are continuing with the mine infrastructure to create a block-cave at the the bottom of the ore-body and eventually they will begin to extract the ore from the the bottom. They will create multiple levels to extract the ore efficiently (similar to what Newcrest do at Cadia now).
Then they have discovered other ore deposits in the vicinity (sound familiar) that they will be able to develop by just creating a horizontal connecting tunnel that would enable them to use the decline and all the crushing / conveyor equipment from the original deposit.

Can anyone see the possibilities that Havieron will create for Newcrest - what if those cores from the Artemis drilling come back with decent grades, what if we discover than the Eastern breccia expands, what if they find more mineralisation at the Apollo and Atlas targets to the North of us.
The story at Havieron has a long, long way to go yet before we even look at possibilities like Scallywag, Parlay, Goliath, etc, etc.
