This is what gets on my wick with Shanta as, whilst I'd previously praised Zurrin's presentations, they're increasingly burying the bad news, like this tucked away in yesterday's RNS:
"Gold produced for the period was 12% less than budgeted mainly attributable to poor grinding efficiency that affected gold recovery. The decrease in grinding efficiency in Q3 is partly attributable to poor cyclone classification due to unavailability of the cyclone spares, ore hardness and increased milling throughput. DRA-South Africa is conducting a study with recommendations in Q4 on the way forward to be implemented".
Now they've just tweeted (not RNS'ed) a transcript of the call with analysts which contains various bits I'm sure people would have wanted to know:
"In the second half of September, we encountered ground instability at Bauhinia Creek 850 level of the crown pillar and this resulted in about 11,000 tonnes, grading 4.29 grams per tonne for about 1,600 ounces, being indefinitely unavailable for mining due to safety and operational reasons. So this was in fact the hanging wall, which became unsafe to continue mining. Around November 10th we will expect to start removing a further 13,500 tonnes, grading 9.7 grams per tonne containing 4,200 ounces, so we'll expect to remove that from the 900 level at the B.C. crown pillar, this is about 50 metres above the 850 level. We've now accessed this area and we've had to develop 80 metres to get into here and so we've now accessed it, and we're preparing it for blasting."
and a bit more general:
"we managed our equipment carefully amidst ongoing pressure from unreliable supply chains and cost inflation. These pressures cannot be underestimated and taken for granted"
and
"The overall grade of 3.18 grams per tonne in the plant is a function of the blending that we did from open pits underground and run of mine stockpile sources. Gold produced for the period was impacted by poor grinding efficiency within the mills that affected gold recovery. Particularly, as we fed high grade ore from the crown pillar we saw the efficiency reduce. So, the decrease in grinding efficiency in Q3 is partly attributable to the poor cyclone classification. And this really goes back to the unavailability of cyclone spares in the supply chain, or hardness changed temporarily, and higher grades impacted some of that recovery."
Now none of these are the end of the world as such but it irritates me that we don't get the full story.
Also the analyst call says "Work is underway now, as we speak, to update the M&I resources at Isulu and Bushiangala, which we expect should be ready around mid-December" yet in the public RNS it says "Updated Mineral Resource Estimate, targeting conversion from Inferred to Indicated resource category at both Isulu/Bushiangala and Ramula, expected in Q1 2023".
It would be nice if they could just tell everyone, straight up, in an RNS, at the same time...
