Vancouver, Canada -- Mawson Resources Limited ("Mawson") TSX -- MAW; Frankfurt -- MXR, PINKSHEETS- MWSNF announces the final results from the Phase 1 drill program and updates results from the summer field program from the Rompas gold project in Northern Finland.
Mr. Michael Hudson, President & CEO, states, "Our first drill program at Rompas returned some very exciting results, notably 6 metres at 617 g/t gold in drill hole ROM0011 including 1 metre at 3,540 g/t gold, released on May 31, 2012 and 1 metre at 114.5 g/t gold in drill hole ROM0015, released on July 10, 2012. These results confirm the significance of the hundreds of bonanza grade surface occurrences that were channel sampled over the last two years and with the new drill information, we are now starting to define a continuous envelope which contains the high grade gold. Nevertheless, we are only beginning to scratch the surface of a project that exceeds 6 kilometres in strike length. Due to drill access limitations, only two small, lower priority areas were tested during this Phase 1 program.
In addition, new early stage Rompas-style surface discoveries have recently been made 8 kilometres east of Rompas at Rajapalot, significantly adding to the prospectively of this exciting area."
Full results from Phase 1 drilling area now available, as provided in Table 1. New results released here include 1 metre at 4.3 g/t gold from 17 metres depth and 1 metre at 3.2 g/t gold from 68 metres in drill hole ROM0037.
Although the program only tested a small proportion of the 6 kilometre strike of mineralization (Figure 1a) down to an average depth of 50 metres, some spectacular drill discoveries were made. In total 39 holes for 4,187.8 metres were drilled at South Rompas in two small areas: the North (160 metre strike) and South Blocks (250 metre strike) (Figures 3 and 4). Drilling along the remainder of the trend awaits further permitting. The North Block corresponds to significant surface mineralization and was drill tested with 15 holes for 1,683.6 metres (Figures 5a and 5b). Ten holes drilled in the North Block returned gold of >0.5 g/t over one metre or better. Drilling in the South Block was of a lower priority, as it tested the southern extension of the interpreted mineralized trend under soil cover (Figure 6). Twenty-four holes for 2,504.3 metres were drilled over 240 metres of strike, two of which returned gold of >0.5 g/t over one metre or better. A majority of drilling in the South Block was designed in an east-west traverse to better understand the geology beneath glacial soils, and investigate nearby geophysical anomalies.
Assay results reported in this release are from 16 drill holes: ROM0020, ROM0025, ROM0028 and ROM0035-ROM0037 from the North Block of South Rompas (Figures 3 and 4) and ROM0016, ROM0019, ROM0021, ROM0024, ROM0026 ROM0031-ROM0034, ROM0038, ROM0039 from the South Block of South Rompas (Figures 6). Drilling was completed on 20 to 40 metre spaced sections with drill holes averaging 100 metre depth, with 1 to 4 holes drilled on each section. Holes were mostly drilled at 45 degrees to the west and east (Table 2).
Compilation of drilling data has led to an improved understanding of the Rompas mineral system. Drilling 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 20 metres wide hosting 20% to 30% veining. Some veins host significant gold with visible gold noted in 12 drill holes. Mineralized veins are similar in texture and composition to those that are not mineralized. Recent research has defined an altered mafic volcanic as host to mineralization and delineated a geochemical halo which has the capability to show the extent of an envelope that hosts the high-grade gold (Figures 5a, 5b and 7). Although bonanza gold grades may not be continuous at the scale of current drilling (20 to 40 metre spaced sections), this envelope enables better drill targeting at both prospect scale and within individual high grade structures.
On receiving further drill permissions, Mawson will test the priority targets along the 6 kilometre long Rompas trend, and drill test closer to the bonanza grade veins discovered during this Phase 1 program.
Summer Exploration Program Update
In addition to the recently completed drill program, a 12 person team has been undertaking an active summer exploration program at Rompas and surrounding areas. Work completed to date includes 62 line kilometres of geophysical surveying (gradient array induced polarization) over the Rompas trend; a 1,200 sample soil grid and rock chip program over the prospective sequence in the semi-regional Rompas trend and regional prospecting.
As a result of the prospecting work, a new area of Rompas-style mineralization has been discovered at Rajapalot, 8 kilometres east of Rompas (Figure 1a). The area was targeted with airborne radiometrics and surface soil geochemistry (Figure 1b). Visible gold and uraninite has been found within carbonate veins within albitized basalt in 3 sites (2 boulders, one outcrop) within an 800 metre trend where 36 radioactive spots have been identified to date. All radioactive sites have been discovered under thin soil by means of hand-held spectrometers and routine sampling is yet to take place. This trend lies within a broader 5 kilometre long anomalous area where 96 radioactive sites have been located where the rocks contain uraninite within in albitized, sericitized, sulphide-bearing and variably amphibole altered quartzites. Reconnaissance grab sampling of some areas has been undertaken, work continues and results of sampling are awaited.
In other news, in keeping with the Company's strategy to focus in Scandinavia, Mawson has staked seven claim reservations through Finland for a total of 104,223 hectares which have potential for Rompas and other styles of mineralization. In addition, in Sweden the Company has staked six claim applications in three project areas for a total of 23,053 hectares. Information regarding these additional claims will be announced as further research is conducted.
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.
