Hi Hagetaka,

Like Albert M I don't particularly like or condone the responses to your posts. I have seen similar responses on other forums and don't fully understand why.

Someone responded to a poster who did such a thing by saying ( hyperbolically paraphrased) - 'if you come into the local drinking hole here don't even appear to be criticizing the local brew - take a few sips and get a feel for the place or someone will tap you on the shoulder and ask you to 'step outside' with them".

I have been contemplating a post on the extractive processes of BLK's refractory ores for awhile and will try to tread carefully with the following.

It seems to me there are 4 main types of ore BLK will be dealing with

Oxide - standard well tried practice and the principal source for the next few years

Free Milling UG quartz with Au - again pretty standard processing - gravity +?CIL

Refractory UG As Sb rich gold ores at high grades - roasting, BIOX now the standard method
at fairly reasonable recovery rates.

Finally the calcined tailings - a set resource but no stated method of Au extraction ATM I believe.

BLK has ample oxide ore for several years but from what I understand they plan to mix it with other ore sources as and when the mine plan suits. First addition would likely be the Free Milling followed by refractory and or calcined types IMO.

Below is some information I have googled over the last hour or so in a search to try and find out how much ore the BIOX system can handle. Hagetaka mentions 800tpa Hagetaka

This seems a bit low to me unless it is from a flotation product and represents many more tons out of the ground or some other thing Aurefice or Nabaru and others have covered this very recently. Excuse crossing posts.

I will only leave the following images from my brief research on this topic.

PS. Hagetaka I looked at a small selection of your posts and didn't see any images or links. They say a picture is worth a thousand words sometimes...

I posted one image from a presentation earlier in the year that indicates 800tpa. This number was referenced at least twice in BLK announcements. I've been trying to ascertain the numbers reliability. The numbers in their presentations don't add up and I'm not going to assume that they are "typos".

It's getting a little late in the evening for me to post much now. However, here are some links and images for the time being:
