| ABSTRACT: | Kingsrose Mining (ASX:KRM) advises that the update Mineral Resource at the Way Linggo mine in Indonesia is 354,000 tonnes at 7.2 g/t Au and 68 g/t Ag for 81,000 ounces of gold and 769,000 ounces of silver. This estimate, is based as at June 30, 2018, and is reported in accordance with the JORC Code (2012 ed.) This is the first significant update to the Mineral Resource since production resumed at Way Linggo and the Company’s shares were re-instated to trading in 2017. The mine is now in full production using conventional open cut methods (see photo, Figure 1). GEOLOGY AND GEOLOGICAL INTERPRETATION The Way Linggo gold / silver deposit is centred on an extensive epithermal quartz vein system, which has been modelled over a strike of approximately five hundred metres. Conceptually, the interpreted domains for estimation are individual, sub parallel, continuous epithermal veins. For practical purposes however, closely related parallel veins, and hence some internal wallrock dilution, is included into the estimation domain definition wireframes. DRILLING, SAMPLING, SUBSAMPLING AND SAMPLE ANALYSIS The samples informing this Mineral Resource estimate are from a mixture of diamond drill holes (drill core) and underground face sampling. Typical, for a historical project of this duration, a wide range of drilling diameters (from BQ to PQ) are known to have been used. Face sampling is taken from an insitu rock face into a sample bag using a standard geological hammer according to typical industry practice. Core is cut by diamond saw and half core used for sampling, the remaining half is archived. For gouge, soft and friable core a manual knife (or similar device) is used to approximately halve the core. Face chips are nominally chipped horizontally across the face/trench, sub set by geological features. Sample collection is manual via a geological hammer. Core samples and face samples sampled on site in this way are dispatched to the laboratory for further sample preparation (crushing, splitting if required, followed by fine grinding), subsampling and analysis. Gold concentration in diamond drilling samples is determined by fire assay lead collection followed by flame atomic adsorption spectrometry. Analysis for silver in diamond drilling is variable historically with analysis using industry standard methods for the period of drilling. Gold and silver concentrations in face/trench samples is determined by aqua regia digestion with an AAS finish. The nature, quality and appropriateness of the sampling, sample preparation and analysis technique are typical for mineralisation and resource estimation of this type. | |
