Far West Mining Reports High Grade Assays from Western Extension of Santo Domingo
|
| |
Vancouver, BC. - Far West Mining Ltd. (TSX: FWM) is pleased to report the results from six diamond drill holes at Santo Domingo. The drill holes confirm the extension of mineralization of the Santo Domingo deposit approximately 50 metres to the west. The existence of the extension was indicated by earlier drilling and reported in the news release of May 11, 2010.
In April and May 2010, Far West Mining (the "Company") completed a program of six diamond drill holes for a total of 1,537 metres. Four drill holes were completed at the western edge of the Santo Domingo deposit and two holes were targeted on a breccia body in the centre of the deposit that had been identified during earlier drilling for metallurgical sample material. Drill results are summarised in Table 1.
Drill holes 370 and 387 (see Figure 1, and reported in the news release of May11, 2010), located 200m apart on the western edge of the deposit, were targeted to intersect the bounding fault at a depth of approximately 300m. The holes failed to intersect the fault and continued in mineralization. In response to this unexpected result, the Company drilled four additional holes to define the western limit of the deposit.
Drill holes 394 and 395 were drilled from the same pad towards the deposit with different inclinations. Drill hole 394, drilled at 70°, intersected a sequence of barren tuffs and limestone before ending in a previously known diorite intrusion. Drill hole 395, drilled at 50°, intersected thick manto mineralization starting at 138m, thereby extending the previous limit of mineralization by approximately 50 metres to the west. Copper mineralization consists of high grade chalcopyrite and bornite hosted in massive hematite mantos.
Drill hole 396 was positioned 100m further north and intersected the same high grade copper mineralization, confirming the extension to the west. Drill hole 397, positioned 100m north and even further west, intercepted three narrower manto horizons in a sequence of limestone and tuff. The western edge of the deposit appears to be defined by gradually diminishing mineralization, possibly due to a change in host lithology, as opposed to a previously interpreted discrete fault.

Drill holes 393 and 398 were designed to characterize a previously unknown breccia body in the centre of the Santo Domingo deposit. The drill holes demonstrated the limited extent of the breccia body and confirmed continuity of mineralization in and below the breccia.

Depending on the angle of inclination, true width varies from 77% (50° inclination) to 94% (70° inclination) of the reported widths.
At the data cut-off date for the July 12, 2010 resource calculation, assays from these drill holes were not available, but the lithological logs from the new drill holes were used to determine the limits of mineralization for the purposes of the resource calculation. Inclusion of the new results will not cause a material change of tonnage or grade to the overall resource. However, as the weighted average copper grade of the additional material is higher than the average resource grade (0.62% Cu versus 0.32% Cu) the new results will have a positive impact on the initial mining area.
Assaying Procedures
Samples were subjected to peroxide fusion and analyzed for 18 elements by ICP-AES (induced coupled plasma atomic emission spectrometry). Gold was analyzed by fire assay with atomic absorption finish using a 30g pulverized sample. A QAQC (quality assurance, quality control) program conducted by Far West consisted of the introduction of standard, duplicate, and blank samples into the sample sequence at regular intervals.
