NOVO ANNOUNCES BULK SAMPLE RESULTS FROM COMET WELL
Novo Resources Corp. has released bulk sample results from its Comet Well joint venture (80-per-cent Novo; 20-per-cent Smith/Gardner Mining), part of Novo's greater Karratha gold project, Western Australia.
First-round bulk sample results confirm the potential of the basal conglomerates at Karratha and support Novo's view of significant prospectivity across its Comet Well/Purdy's Reward tenements and, more broadly, the prospectivity of Novo's 12,000-square-kilometre landholdings across the Pilbara.
Highlights:
Bulk samples reported in this news release come from two gold-bearing conglomerate units at Comet Well, the Upper Cannonball conglomerate and Lower Cannonball conglomerate, as well as surrounding rock strata.Bulk samples were collected from two-metre-by-two-metre pits scattered along 1.2-kilometre strike from Cannonball Gully in the southwest to the Purdy's Reward tenement boundary in the northeast (Purdy's Reward is a joint venture on conglomerate/paleoplacer gold; 50-per-cent Novo and 50-per-cent Artemis Resources Ltd.). Thicknesses of samples range from approximately 0.35 to 1.20 metres.The bounds of gold-bearing conglomerates are not readily identifiable by eye, therefore bulk sampling encompassed sections of conglomerate above and below each respective gold-bearing unit in order to better constrain their limits.Processing of each sample encompasses coarse crushing and screening then passing material through a metal detector to collect any nuggets. Once detected, the sample is finely crushed, screened and further processed through a gravity concentrator. Concentrates and tails are analyzed, with the final grade based upon the gold recovered from each of the three sample streams.At Cannonball Gully, Novo has identified what it believes are significant basin-bounding faults that may have been active during sedimentation and controlled LCC deposition. Diamond drilling indicates the LCC continues into the basin, and may open up and become more laterally extensive, particularly to the east. Therefore, Novo believes that exposures of LCC at Cannonball Gully form a small outcropping apex of this important unit. Bulk samples from the mineralized core of the LCC include KX157 (7.14 tonnes) grading 10.40 grams per tonne gold and KX158 (6.85 tonnes) grading 1.51 grams per tonne gold (samples previously reported in the company's news release dated May 31, 2018). Collectively, these two samples represent a 1.4-metre high vertical profile through the LCC with a weighted average grade of 6.06 grams per tonne gold. Nearby samples KX160 (7.17 tonnes) grading 1.99 grams per tonne gold and KX161 (13.5 tonnes) grading 2.62 grams per tonne gold collectively represent a 1.8 m high vertical profile through the LCC with a weighted average grade of 2.40 grams per tonne gold. Gold nuggets recovered from bulk samples of LCC are typically flat, up to 10 millimetres across, weigh a gram or less and occur within sandy matrix between boulders. Boulder clasts in the LCC range in size up to 1.5-metre diameter and are tightly packed.Bulk samples from the mineralized core of the UCC include KX223 (3.78 tonnes) grading 4.53 grams per tonne gold, KX227 (3.40 tonnes) grading 3.06 grams per tonne gold, KX198 (6.44 tonnes) grading 2.26 grams per tonne gold, KX224 (4.11 tonnes) grading 1.29 grams per tonne gold and KX171 (4.96 tonnes) grading 1.22 grams per tonne gold. Gold nuggets recovered from bulk samples of UCC are similar in shape to those of the LCC but are typically larger, up to 18 mm across and weighing up to approximately six grams. Such size nuggets are typical of mineralized conglomerate at nearby Purdy's Reward, therefore Novo believes the UCC at Comet Well may be geologically related to the Purdy's Reward conglomerate. Novo has currently explored a combined length of 3.6 kilometres of UCC and Purdy's Reward conglomerate. This zone remains open at both ends and into the basin. Novo collected circa 300-kilogram bulk samples from trenches at Purdy's Reward late last year. Results from these samples were discussed in Novo's news release dated Feb. 14, 2018.Variability of grade in conglomerate bulk samples is largely a function of the number of nuggets in each sample. Novo also believes the proportion of boulders to matrix in each respective sample significantly impacts variability. Given the nuggety nature of gold mineralization at Karratha, such variability is expected.At Karratha, gold almost universally occurs as nuggets with a thin, two-to-five millimetre halo of fine-grained gold in the matrix of conglomerates. In spite of this, the proportion of gold occurring as nuggets varies widely from bulk sample to bulk sample. Novo believes this may reflect breakdown of nuggets to finer gold particles during processing of some samples. Novo does not see evidence of a significant component of fine-grained, disseminated gold in Comet Well conglomerates.

The multitonne bulk samples presented in this news release serve to provide an indicative grade of the two gold-bearing conglomerates at Comet Well. Novo takes the view that bulk sampling on the scale of 10,000's of tonnes is required to more fully ascertain the grade, distribution, and continuity of these units and to determine the commercial viability of whether a potential mining operation could proceed. Such process is well-known in the diamond industry where trial excavation of very large samples is required to evaluate economics of deposits prior to mining.
Novo plans to use this bulk sample data along with geologic data collected from recently completed diamond drill cores as a basis for a mineralization report, a critical component needed to convert an exploration licence to a mining lease.
Bulk sample processing
Novo staff collected bulk samples discussed in this news release.Bulk samples were submitted to SGS Minerals in Perth, Australia, where they were treated in a test plant detailed in Novo's news release dated Feb. 6, 2018, and May 31, 2018. Because gold mineralization at Comet Well is extremely coarse, the entire sample is coarsely crushed, screened and passed through a metal detector to collect any nuggets.Once detected, the sample is finely crushed, screened and further processed through a gravity concentrator. Concentrates and tails are analyzed, with the final grade based upon the gold recovered from each of the three sample streams. Samples are scrutineered by independent consultants from RSC Mining and Mineral Exploration, Perth, whilst each sample is collected and received into the laboratory, maintaining complete integrity over the chain of custody. All assay certificates and head grade calculations were provided by SGS as secured documents, with the calculations and head grades checked by Novo internal resources and verified by Dr. Simon Dominy. There were no limitations to the verification process and all relevant data were verified.

Dr. Simon Dominy, FAusIMM (CP), a consultant geometallurgist to the company, a qualified person as defined by National Instrument 43-101, has approved the processing and sample grade content of this news release.
