Guyana Frontier provides final 2012 drilling results from Marudi Mountain Project
Monday, Jun 25, 2012VANCOUVER, June 22, 2012 /PRNewswire/ - Guyana Frontier Mining Corp. ("Guyana Frontier") is pleased to provide an update on the results of the remaining six diamond drill holes from the Marudi Mountain Gold Project ("Marudi Mountain") in Guyana, South America. The six holes reported here, totalling 909.5 metres, were drilled at the Marudi North target area from two collar locations, of which three holes encountered gold mineralization. The 2012 drilling program at Marudi North successfully intersected gold mineralization within quartzite-metachert rocks (the "host rock") in six of the nine holes drilled. In all, 1,977.47 metres were drilled in 12 holes at both target areas during the Phase 1 drilling program. Nine holes totalling 1,438.17 metres were drilled in the Marudi North segment of the 2012 drilling program, and 539.30 metres were earlier completed in 3 holes at Mazoa Hill.
Mazoa Hill Target Area
Guyana Frontier's three Mazoa Hill 2012 drill holes showed significant gold mineralization, as indicated by holes MH12-130, -131 and -132. For example,hole MH12-132 returned a weighted average of 2.59 grams/tonne gold over 37.47 metres from 47.03 to 84.5 metres, which included 11.06 metres of 5.85 grams/tonne gold from 63.44 to 74.5 metres, and 2.0 metres of 11.0 grams/tonne gold from 66.5 to 68.5 metres (see Guyana Frontier's news release of May 2, 2012). Guyana Frontier has access to most of the historical drill core from the 1991-1995 and 2004 drilling programs on site in a secure storage facility, and prior to further drilling plans to carry out additional re-logging, re-sampling and re-assaying programs to add further understanding of the historical gold resource, which is not compliant with the standards of National Instrument 43-101 (see Guyana Frontier's review of the Mazoa Hill historical resource estimate in its news release of June 6, 2012).
Marudi North Target Area
At Marudi North, located 1.6 kilometres to the north of Mazoa Hill, Guyana Frontier has begun to define a new zone of gold mineralization, and has collected valuable subsurface geological information for integration with prior results of trenching and soil sampling, and planned geophysical surveys. Previously reported holes MN12-134 returned a weighted average of 4.29 grams/tonne gold over 17.55 metres from 12.50 to 30.05 metres, which included 12.0 metres of 5.54 grams/tonne gold from 12.50 to 24.50 metres, and MN12-135 returned a weighted average of 1.80 grams/tonne gold over 32.24 metres from 23.26 to 55.50 metres (see Guyana Frontier news release dated May 24, 2012).
Three of the last six holes drilled in the Marudi North target area encountered varying amounts of gold mineralization in the host rock. The host rock appears to be faulted and deformed in this western area of Marudi North, which made targeting more difficult. For example, in hole MN12-137, a feldspar-porphyry dyke and extensive faults were encountered at the expected location of the upper host rock target zone, and the lower zone host rock was not intersected until 195.13 metres to 204.94 metres. In hole MN12-138, the host rock was not intersected, despite its suggested strike and direction interpreted from the 2011 trenching program. In holes MN12-140 and -141, the host rock unexpectedly appears to trend westerly and dip southerly. The geological characteristics and mineralization of the host rock at Marudi North is therefore not completely understood, and demands further drilling to determine its full potential.
