Novo recently received necessary Plan of Work approvals for core drilling at the Purdy’s Reward prospect.
The Purdy’s Reward tenement is part of a farm-in and joint venture Novo has with ASX-listed Artemis Resources Limited and is part of Novo’s greater Karratha gold project. As discussed in the Company’s news release dated 31 August, 2017, Novo envisions a two-pronged approach to drilling at Karratha. Scout diamond core drill holes will help allow initial assessment of the depth and thickness of targeted gold-bearing conglomerates. Once target depth and thickness has been determined, large diameter RC holes (17.5 in. diameter) will be drilled to collect bulk samples. Novo has engaged Orlando Drilling to undertake diamond core drilling and FORACO International SA to undertake large diameter reverse circulation drilling. Drilling will commence in areas within which heritage clearance has already been conducted. Core drilling is expected to begin around September 27th and large diameter drilling around October 15th.
Preliminary trenching activities have begun. Novo has recently mobilised a 35 t excavator to site which, in addition to helping construct drill pads, will be used to open up several exploration trenches at Purdy’s Reward. Mobilisation of a hardrock trencher as discussed in the company’s 31 August, 2017 news release, will take place once approvals have been received to upgrade the track into site.
Bulk samples from large diameter reverse circulation drilling and trenching will be delivered to Nagrom Metallurgical Laboratory, Perth and subjected to analysis as follows:
“We are eager to commence exploration activities at Karratha,” commented Dr. Quinton Hennigh, President, Chairman and Director of Novo Resources Corp.“We anticipate diamond core drilling to provide us with a good handle on stratigraphy and target depths. Follow-up large diameter reverse circulation drilling will provide necessary bulk sample material to evaluate grades of this very nuggety gold system. Similarly, bulk samples collected from trenching will provide critical data on grade and gold distribution. Karratha is a very exciting gold discovery, and Novo is ready to meet the challenge of exploring it.”
Karratha Gold Project
Gold mineralisation at Karratha is hosted by a sequence of conglomerate beds, fossil gravel horizons, ranging from a few meters to approximately 20 m thick comprising the base of a much thicker package of sedimentary and volcanic rocks called the Fortescue Group. Rocks of the Fortescue Group were deposited between 2.78 and 2.63 years ago upon 3.0 - 3.7 billion year old igneous and metamorphic rocks that make up the Pilbara craton, an ancient piece of Earth’s crust.
Over the past year, local metal detectorists have excavated gold nuggets originating from weathered conglomerate along an eight-kilometer, southwest-trending corridor between the Purdy’s Reward prospect (please refer to the Company’s news releases dated May 26 and August 15, 2017) and Comet Well. These gold-bearing conglomerates dip gently southeastward under cover at angles of between 2 and 20°. The company secured 100% control over approximately 7000 km2 in areas along strike and down dip from Purdy’s Reward and Comet Well through aggressive staking earlier this year. Novo believes that these gold-bearing conglomerates may underlie significant areas within the greater Fortescue basin. In the Company’s news release dated 12 July, 2017, Novo discussed discovery of gold nuggets in a bulk sample collected from a trench at the Purdy’s Reward prospect. Metallurgical test work conducted on this sample was discussed in the Company’s news release issued 8 August, 2017. The weighted average grade of two splits of this bulk sample was 67.08 gpt Au. Approximately 82% of the gold in this sample was determined to be coarse, mainly nuggets displaying several interesting characteristics. These are commonly flattened with rounded edges giving them an appearance similar to watermelon seeds. Most are coarse, +2 mm and are not attached to quartz or other minerals. Gold is of high purity, +96%, much higher than the gold content of nuggets derived from basement-hosted lode gold deposits from the Pilbara region that commonly display purities of 70-90%. Nuggets display crenulated surfaces thought derived from burial and compaction within a sandy matrix.
In addition to coarse gold, this metallurgical test confirmed a significant fine-grained gold component is present in these conglomerates. Such fine gold, if it is indeed disseminated throughout the conglomerates, could prove important to help evaluate grade and continuity of this deposit.
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.
