Pursuit Minerals Limited announced Heavy Liquid Separation test work, on zinc-lead mineralisation from the southern end of the JB Zone Mineral Resource, on the Paperbark Project, northwest Queensland, has been extremely successful. A composite sample from drill hole PB01-17, which intersected 68m @ 1.39% Zn and 0.05% Pb, was able to be upgraded using HLS to 17.5% Zn, while retaining 85.4% of the originally contained zinc metal. Paperbark Project ­ JB Zone HLS Test Work Program: The Paperbark Project is located approximately 215km northnorthwest of Mount Isa and 25km south-east of the Century Mine in north-west Queensland. It occurs within the Lawn Hill Platform of the Western Succession of the Mt. Isa Province. The project consists of two exploration permits (EPM's 14309, 25191), covering an area of approximately 110km. Previous exploration focused on the JB Zone, where a Mineral Resource of 10.4Mt @ 2.7% Zn, 0.2% Pb, 1g/t Ag at 1.5% Zn cut-off grade and classified as Inferred in accordance with the JORC Code (2012), has been defined. Drill hole PB01-17 was drilled through the southern section of the JB Zone Mineral Resource in order to investigate the variation and extent of higher grade zinc and lead mineralisation, within the Mineral Resource and to provide a thick section of zinc and lead mineralisation for HLS test work. A 68m section of drill hole PB01-17 returned 1.39% Zn and 0.05% Pb, from 271m down hole depth. Quarter core samples from the mineralised section (271m-339m down-hole depth) of the JB Zone were submitted to ALS Metallurgy Services for HLS test work. Sample Preparation: Quarter core samples from the mineralised section (271-339m) were weighed and composited into a single bulk sample. The bulk sample, PB01-17 Composite, was crushed to P100 16mm. A head sample, 2 x 2kg sighter test samples and 2 x 5 kg HLS test work samples were split off. One sighter test sub-sample was crushed to P100 8mm. Following sighter tests, one 5kg sub-sample was sized at 8mm, 4mm, 1mm and 0.045mm. On completion of the HLS test work on the P100 16mm material, the second 5kg sample was crushed to P100 8mm and sized at 4mm, 1mm and 0.045mm for further HLS testing. Fractions in the -16/+1mm range were separated by static HLS using diiodomethane as the heavy liquid. The -1mm faction was separated by centrifugal HLS using diiodomethane. A number of sighter tests were conducted at HLS separation densities of 2.75, 2.85, 2.95 and 3.3kg/dm. These initial tests showed that recovery to the HLS sink at 2.85kg/dm was highly variable, indicating that a large proportion of the composite samples had a density close to 2.85kg/dm, allowing small density variations to result in large changes to the float/sink ratio. The sample fractions were combined, and a test run at 2.8 and 2.9kg/dm resulted in more stable sink/float ratios. HLS of the P100 16mm fractions indicated significant upgrading of the zinc, with approximately 74% of the contained zinc reporting to the +2.9kg/dm fractions. However, a further 18.7% of the contained zinc was retained in the +2.8/-2.9kg/dm fraction of the -16/+8mm material. In addition 1.5% of the contained zinc reported to the -0.045mm fraction. In order to improve recovery on the 2.9kg/dm fraction a sub-sample was crushed to P100 8mm and separated under the same conditions as the P100 16mm sample. Zinc recovery to the sink fraction improved with approximately 85% (up from 74%) of the zinc reporting to the +2.9kg/dm fractions. The additional crushing increased losses to fines with 3% of the total zinc contained in the -0.045mm fraction. Heavy Liquid Separation (HLS) on zinc-lead mineralisation, from drill hole PB01-17 at the JB Zone on the Paperbark Project, north-west Queensland, was proven to be very successful. Using a fluid of density +2.9 kg/dm and a crush size of P100 8mm, 85.4% of the contained zinc reported to the HLS fraction, with a subsequent upgrade in the zinc grade to 17.5% and a 10-fold decrease in overall sample mass. The HLS results indicate that pre-concentration of the JB Zone Mineral Resource, has the potential to increase the grade of zinc placed into the milling and flotation section of a processing plant to >15% Zn and reduce the mass of material to be processed by a factor of 10. The substantial increase in zinc grade and reduction in overall sample mass, has the potential to significantly decrease both the operating and capital development costs for processing the JB Zone Mineral Resource.
