FURTHER RESULTS OF metallurgical tests at a site in Clontibret, Co Monaghan have come back “highly positive”, Conroy Gold and Natural Resources said today.
The gold exploration and development company, developing a gold mine at Clontibret, conducted tests on the “flotation recovery”, after tests earlier this month relating to mill design.
The gold flotation recovery, at 90 per cent, is higher than assumed and the company said “this is most encouraging both technically and financially”.
These results mean that processing of the gold should go more smoothly. Part of the process involved is extracting metal from the rock which contains it which is ground down in the hope of getting as much gold as possible out of it.
The results also indicate an 8 per cent sulphur grade in concentrate where a grade of 12 per cent had been assumed. The lower sulphur grade in the concentrate is highly advantageous as it will reduce process operating costs.
The laboratory flotation full locked cycle tests were completed and the results are positive. The importance of these tests is that they simulate what might be achieved when the processing plant of the mine is in continuous operation. Steady state conditions were achieved as soon as the fifth and sixth cycles. The firm said this is a “very satisfactory outcome” as the results suggest an efficient and smooth running flotation process.
Commenting today, Chairman of Conroy, Professor Richard Conroy said the results are very encouraging and fit in with the company’s plan to bring a mine into production in three years’ time.
Further metallurgical test work is ongoing.
