Ann: Laneway to Resume Gold Production from Agate Creek, page-58

@Mercury9 - regarding this part of your post -

"Partly this was due to MAR not providing adequate funds for cyanide stock for the processing. The processing manager sounded like a decent, hardworking fellow and was spitting chips about the lack of funding for the cyanide feed before he got the boot.did your contact."



Was it MAR or OPS's responsibility to stock enough cyanide solution? Obviously its a highly regulated substance and probably not cheap, surely if they needed more cyanide to increase gold recovery its just a case of doing it right away and argue about the costs later? Otherwise you are sending gold directly to the tailings dam, which is insane. I have heard that even moderate copper content in the ore sends cyanide consumption through the roof - sometimes to the point where the cost of the cyanide exceeds the improvement in gold recovery? Lots of people came unstuck trying to operate CIL plants in a high copper environment, just like at Osborne Mine where the CIL plant was never really utilised, guess where that CIL plant ended up after being sold? Yep you guessed it - Lorena.

Anyway - at least there is no copper at Agate Creek to stuff up cyanide leach recoveries but you would hope that a test batch or two goes from Agate Creek to Lorena (or a reputable met lab) so that they can check if the Agate Creek ore is actually compatible with the Lorena plant? I know LNY has a decent geologist but do they have anyone with gold metallurgy experience? Because if they don't do this due diligence, and the Agate Creek ore is somehow incompatible with what is at Lorena and they have committed to road train contracts then LNY will be the proud owners of the worlds most expensive waste rock dump located within someone else's mining lease. That would be embarrassing.
