VANCOUVER, July 10, 2012 /CNW/ - Mawson Resources Limited ("Mawson") (TSX: MAW) (Frankfurt: MXR) (PINKSHEETS: MWSNF) announces results from a further 9 drill holes from the Rompas gold project in Northern Finland. The highlight result is 1 metre at 114.5 g/t gold from 44 metres depth in drill hole ROM0015.
Mr. Michael Hudson, President & CEO, states, "This second batch of results from our first drill program at Rompas, with a best intersection of 1 metre at 114.5 g/t gold in drill hole ROM0015, is a successful follow up to the initial drill results released on May 31, 2012, which contained 6 metres at 617 g/t gold in drill hole ROM0011 including 1 metre at 3,540 g/t gold.
Although it is early in our understanding of the controls on gold mineralization, we are beginning to define a linked vein array that hosts high-grade gold structures within a broader gold anomalous zone characterized by hydrothermal calc-silicate veining and alteration. Given we have tested only a small area in a much larger mineralized system, future exploration work will test two different scales. The first is to drill the large known mineralized area over its 6 kilometre trend and the second to drill and understand the controls and continuity of gold mineralization within individual high grade structures."
Phase 1 drilling has now been completed at Rompas for a total of 39 diamond holes for 4,178 metres. Drilling during this Phase 1 program has tested two small windows of the larger 6 kilometre mineralized strike at Rompas (Figures 1 and 2). Drilling in other areas awaits further permitting. Assay results reported in this release are from 9 drill holes: ROM0015, ROM0017, ROM0018 and ROM0022 from the northern block of South Rompas (Figures 3 and 4) and ROM0023, ROM0026, ROM0027, ROM0029 and ROM0030 from the southern block of South Rompas (Figures 3 and 5). Results from a total of 24 from 39 drill holes have now been released.
The northern block corresponds to significant surface mineralization and has now been drill tested over a 160 metre strike (Figure 4). All 4 holes reported in this release from the northern block returned gold >0.5 g/t over one metre or better (Table 1). In contrast, the southern block tested the southern extension of the interpreted mineralized trend under soil cover and has now been drill tested over 240 metres of strike (Figure 5). Holes reported from the southern block did not return mineralization above 0.5 g/t gold. Drilling was completed on 20 to 40 metres spaced sections with drill holes averaging 100 metre depth, with 1 to 4 holes drilled on each section. Holes were drilled at 45 degrees to the west and east (Table 3, Figures 6 and 7).
This drill program has provided the first opportunity to sample continuously across the mineralized "footprint". Drilling has confirmed the width and scale of a >100 metre wide hydrothermal veined mineral system with a defined hanging wall and footwall. The zone is variably but consistently calc-silicate (actinolite/tremolite and calcite) veined with multiple zones up to 20m wide hosting 20% to 30% veining. Some veins host significant visible gold. Mineralized veins are texturally and compositionally similar to those that are not mineralized. The calc-silicate veins are thought to have formed during an early structural event and have been deformed by later geological events.
The drilling was undertaken by Olstam Borrteknik AB of Sweden who provided 47 millimetre diameter core and Arctic Drilling Company Oy Ltd of Finland who provided 50.7 millimetre diameter core. Drill recoveries are excellent and average close to 100% in fresh rock. Drill intersections are estimated to be 70 to 90 per cent of the true width. After photographing and logging, core intervals averaging one metre in length were cut in half at the Geological Survey of Finland core facilities in Rovaniemi, Finland. These half core one metre samples weigh two to three kilograms. The samples were then transported by Mawson personnel to ALS Chemex Ltd's laboratory in Pitea, Sweden where the samples were prepared and sent to ALS Chemex Ltd's laboratory in Vancouver, Canada to be analyzed by Au-ICP21, GRA-21, ME-MS41u, PGM-ICP27 and ME-MS61u techniques. The QA/QC program of Mawson consists of the systematic insertion of certified standards of known gold content, with blanks at the beginning of each batch. In addition, ALS Chemex inserts a number of blanks and standards into the analytical process. The remaining half core is retained on site for verification and reference purposes. Test work has shown >90% of gold at Rompas to be fine and <100µm in diameter. The qualified person for Mawson's Finnish projects, Mr Terry Lees, VP Exploration for Mawson and Fellow of the Australian Institute of Geoscientists has reviewed and verified the contents of this release.
