FIRST COMET WELL BULK SAMPLE YIELDS NUMEROUS GOLD NUGGETS
Novo Resources Corp. has provided an update of processing of bulk samples from Comet Well, part of Novo's greater Karratha gold project located in the Pilbara region of Western Australia.
During bulk sample processing, rock is first crushed and screened, and the minus 6.0-millimetre-plus-2.5-millimetre fraction is fed through a conveyor fitted with a metal detector so that coarse gold nuggets can be isolated and extracted for study. The remaining material is set aside for further gold analysis. Eighty nuggets, some partially embedded in rock matrix, were recovered from bulk sample KX157 (7,143 kilograms), the first sample to be processed through the test plant at SGS Minerals, Perth (please refer to Novo's news release dated Feb. 6, 2018, for further details).
Bulk sample KX157 was collected from a trench exposing boulder conglomerate at the Powerline prospect. Importantly, this sample originates from a position approximately 0.3 to 0.8 metre above the basal contact of the conglomerate package suggesting a thicker section of conglomerate is mineralized at Comet Well when compared with Purdy's Reward where most gold is concentrated within a half metre of the basal surface. Metal detector strikes are recorded over approximately four m of conglomerate thickness at the Powerline prospect.
Recovered nuggets from bulk sample KX157 range in size from three millimetres to two centimetres. In spite of two stages of crushing, most appear intact and relatively unscathed retaining their characteristic flattened melon seed appearance, a clear indication of a water-worn alluvial origin. Fine-grained halo gold particles are observed around nuggets partially encased in rock matrix similar to that observed around nuggets recovered from Purdy's Reward. Nuggets ultimately undergo further treatment to remove rock matrix so that an accurate mass of gold can be determined and important information about nugget size can be recorded for statistical purposes.
Following nugget extraction, bulk sample material is subjected to further processing including finer grinding and gravity gold separation. Samples of concentrates and tailings are collected from various points as material passes through the test plant. Once all subsamples have been analyzed, the Au grade of the bulk sample can be calculated.
Processing of bulk samples has been slower than expected due to a number of factors including rock hardness, additional screening steps, and complexities around tail homogenization and sampling. Various modifications have been, and are being, made to the test plant to improve reliability and increase capacity to process the Comet Well conglomerate within a well devised quality assurance/quality control framework. Steady-state processing is estimated to be achieved within six weeks. Grade results for the first few samples from the Powerline prospect are now expected to return by late May. Currently, there are 18 samples from Comet Well in the queue at the laboratory.
"Treatment of bulk samples has required certain modifications to the test plant at SGS resulting in a modest delay in the return of grades from recently collected Comet Well samples," commented Dr. Quinton Hennigh, president, chairman and a director of Novo Resources. "Nonetheless, we are very pleased to see numerous gold nuggets emerge from the first bulk sample to be processed, KX157. This result provides us confidence that our strategy of collecting plus-five-tonne samples is appropriate for this style of mineralization. In many respects, we are dealing with a gold deposit akin to diamondiferous kimberlite, rock that is routinely bulk sampled to yield sufficient diamonds for grade estimation. As done for diamonds, we are analyzing the size of gold nuggets to provide statistical data to better understand this deposit. We look forward to receiving further data including grade from this sample and several others from Comet Well by late May."
Quality control and quality assurance
Novo staff, under the supervision of Dr. Hennigh, collected bulk samples discussed in this news release. Bulk samples are being submitted to SGS Minerals in Perth, Australia, where they are treated in a test plant detailed in Novo's news release dated Feb. 6, 2018. Samples are scrutineered by independent consultants from RSC Mining and Mineral Exploration, Perth, whilst each sample is collected and each sample is treated at the laboratory.
Dr. Quinton Hennigh, the company's, president and chairman, and a qualified person as defined by National Instrument 43-101, has approved the technical contents of this news release.
