RE: Putting the Record straight7 Nov 2021 10:06
The PFS was based on drilling upto February 21.
The last Jorc compliant drilling results were announced on 28th January which could be included in the PFS.
These results were from drilling completed around end of Nov early December 2020 and upto Xmas before they went to assay.
End of Jan results 138,504m drilling completed
28th October 210,629m drilling completed
Therefore there are 72,125 of drilling not used in the PFS
Of the 138,504m only a small proportion will have been used for the PFS
I’ve estimated around 140-175,000m aren’t in the PFS.

There are 3 plans on this RNS first one at 4800 reduced level that’s close to the top of the ore body, on it can be seen the black outline of what was included in the MRE.
Also can be seen squares/shells/cubes where infill drilling has been targeting.
At this level there’s no Northern breccia included.
Go down to the next level 4500 that’s 350m in to the ore this is the bottom of the PFS there’s hardly any black lined MRE resource in the Northern breccia, these weren’t included in the PFS.
Between 4800 and 4500 on the SE side of the Dyke the breccia outside the sulphide high grade squares within the black lines are not included in the PFS.
The infill drilling here has been adding these breccia to the next MRE.
The area to the NW of the Dyke is mainly crackle from 4800 downwards but increasingly turning to cemented further down.
Between 4500-4200 you can see the Northern corridor forming, the infill drilling has been increasing these cemented breccia zones and finding high grades sections.
Infill drilling below 4200 level has been finding more high grade sections and cemented breccia. It all depends in these areas whether they have completed enough infill drilling to include in the next MRE.
The Eastern breccia will definitely not be in the next MRE only 5 drills so far not enough.
There’s 37m tons of maiden MRE not in the PFS most of these should be included in the next MRE but the mining plan may exclude some of these. Most of these are surrounding the sulphides only a small proportion are in the Northern breccia.
There should be a big increase in the resource estimate within the Northern breccia between 4500 and 4200 and maybe lower.
The sulphide zone below 4200 has high grades but the actual volumes of it aren’t that great but they’ve been hitting this zone with infill drilling and should be included. The grades here though are high and volumes of gold/ copper should be good.
Could this double the initial Maiden resource well yes quite possibly if they have completed enough infills of the shells.
Double the PFS resource very easily
