Guyana Goldfields Inc. announced the results of hole MKD 187 drilled into the central mineralized zone at the Mad Kiss satellite deposit at the Aurora Gold Mine, located in Guyana, South America. The purpose of the hole was to confirm the distribution and continuity of gold grades within the dip plane of the mineralized quartz-feldspar porphyry. The hole was drilled at an inclination of -73 degrees along an azimuth of 316 degrees and was terminated at a depth of 345.0 metres (‘m’). The hole returned an average of 6.11 g/t gold over a core interval of 301.4m, starting from 14.1m down hole. The intercept included an Upper Porphyry Zone from 14.1m to 134.2m grading 6.40 g/t and a Lower Porphyry Zone from 188.0m to 315.5m grading 7.67 g/t separated by a Mixed Zone of both porphyry and metasediments from 134.2m to 188.0m grading 1.77 g/t. Both the Upper and Lower Zones were comprised of shorter, high-grade subintervals of extensional veins, stockworks and breccias displaying intense silica-sericite-pyrite alteration. A complete summary of the assay results from the hole is tabulated below followed by a photo illustrating the alteration and veining from a portion of the hole. This work was completed as part of the Company's approved 30,000 m drill program for 2019. The Company currently has two surface diamond drills and a single RC rig working at Aurora. The intent is to swap one of the surface rigs out for an underground drill once the decline has been sufficiently advanced. Analytical work was performed by MS Analytical of Langley, British Columbia, a commercial laboratory with both ISO 17025 (Testing and Calibration Laboratories) and ISO 9001 (Quality Management Systems) accreditation. Sample preparation and assays are done at their facilities in Georgetown, Guyana. Samples are dried, 1kg is crushed to 2mm, a split is then pulverised to 85% passing 75µm, preparation code PRP-920. Assaying is done by a 50g fire assay with an atomic absorption finish, assay code FAS-121. Samples which return above 10 g/t are given a gravimetric finish, assay code FAS- 425. High grade intervals identified in core by Company geologists are assayed by metallic screening. 500g of sample is screened to 106 µm and the entire plus fraction is assayed while the minus fraction is assayed in duplicate. Both fractions use fire assay techniques with gravimetric or instrumental finish, assay code MSC-550. In addition to laboratory internal duplicates, standards and blanks, the Company inserts standards, blanks and duplicates representing 5% of assays for standards and 4% of assays for both blanks and duplicates to monitor quality control.
