Newmac Resources Ltd. Drills 0.36 G/T Gold Over 0.3 Metres And 7.4 G/T Silver Over 0.45 Metres Raft Gold Property

The board of Newmac Resources Ltd. presents the results of the recently completed 1,272 metre 5 hole diamond drilling program on its recently optioned early stage Raft gold property near Vavenby, B.C. 

The 33,641.71 hectare Raft property hosts several shear zone and intrusion associated high grade and bulk tonnage low grade gold, tungsten-copper-lead skarn, zinc-lead manto and zinc-lead +/- copper massive sulphide targets including the recently discovered Bridge gold zone where intrusive hosted quartz-sulphide material dug up from a shallow trench returned 46.7 g/t over a sampled length of 2 metres (true width unknown) (see press release dated October 29, 2010).

The five diamond drill holes Newmac completed, tested for the down dip projection of the surface mineralized zone over a 300 metre wide approximately east west section of the over 2 kilometre long by over 2 kilometre wide target area to a vertical depth of up to 225 metres.

The geology from examination of new drill core has similarities to other Cretaceous aged western north American intrusion associated gold deposits such as Donlin Creek, where gold is hosted by arsenic, antimony and mercury enriched quartz-carbonate-arsenopyrite-pyrite shear and tension veins within faulted biotite granitic and rhyolitic dyke rocks and Fort Knox where gold -bismuth-tellurium quartz shear veins occur within a granite host.

Unlike Donlin Creek the Raft mineralization appears to be from a deeper mineralizing system with negligible mercury, little antimony and ductile shear hosted quartz vein mineralization and shallower than Fort Knox as bismuth does not occur until deep in the drill holes.  Like Donlin Creek the mineralization is closely associated with structurally controlled biotite granite dyke swarms that intrude both older biotite granites and hornfelsed and variably hydrothermally altered sheared metamorphic cover rocks.

Hole R10-01 was collared 40 metres at a bearing of 300 degrees from the high grade gold trench sample and was drilled at a bearing of 120 degrees and a dip of -46 degrees to undercut the trench directly below the high grade trench sample as recommended David. R Bridge, P.Geo.  Newmac’s project manager for the completed surface phases including the recently completed trenching program.  The hole was drilled to a depth of 294.1 metres.

The intervals detailed in the table below occur in highly sheared, quartz-sericite altered and weakly pyrite mineralized quartz shear and fracture veins.  Arsenic is also strongly anomalous.  The mineralization is underlain by 22 metres  (drill length)of lower grade gold-arsenic  values.  The upper part of the interval is about 20 metres deeper than a vertical projection of the surface mineralization indicates.  Additionally numerous other weakly gold –arsenic mineralized intervals occur further down hole.   At the bottom of the hole pyrrhotite was intersected over pyrite and bismuth values were increasing over arsenic.

Hole R10-02 was collared at the same location as and drilled at a bearing 30 degrees south of hole 1.   This hole intersected mostly intrusive rocks. No gold intercepts greater than 40 ppb gold were reported.

Hole R10-03 was collared at the same location and drilled at a bearing of 90 or 30 deg.  north of hole 1.  Compared to hole 1 this hole intersected much less intrusive although the extensions of sulphide mineralized structures appeared at about the same depth indicating a northerly strike and steep dips.  The best intersection was from 259.2 m to 259.6 metres returning 0.123 g/t gold with weakly anomalous arsenic.   No other intersections returned greater than 0.07 g/t gold.

Hole 4 was drilled directly under hole 3 at a dip of -55 deg.  This hole intersected deeper extensions of the intrusive and mineralized structures encountered in hole 3.  From 110-111.4 metres an intercept of 0.11 g/t gold was returned along with weakly anomalous arsenic.  From 111.4 to 111.85 in the same structure a value of 7.4 g/t silver along with weakly anomalous gold, and tungsten were intersected.  This intersection and the similarly located intercepts in holes 1 and 3 may be the down dip extension of the structure hosting the surface high grade zone.  Similar to hole 1 this intersection occurs within a larger interval of more weakly gold mineralized shear intrusive. 

From 304.9 to 305.2 a value of 0.36 g/t gold was intersected along with weakly anomalous arsenic, lead and silver.   This structure may be the one intersected in hole 3 at 259.2 m.
Hole 5 was collared 100 metres at a bearing of 120 degrees from hole 1-4 and was drilled back towards hole 1 at a dip of -45 degrees.  The top 30% of this hole intersected intrusives with the bottom 2/3 a mixtures of metasediments and intrusives.    Numerous variably mineralized structures were also intersected.  From 118.87 to 119.6 a mineralized structure returning gold values of 0.11 g/t gold with anomalous arsenic and weakly anomalous antimony was intersected. 

The drill used was a unitized AR 125/AR 250 drill supplied by DJ Drilling Ltd. of Aldergrove, B.C.  Producing HQ sized core.   The field portion of the program was managed by Leopold J. Lindinger, P.Geo.  of Renaissance Geoscience Services Inc. from Kamloops, B.C.

Newmac management will evaluate these results with respect to the mineralization found at surface and the many other exploration targets on this property.

Chain of Custody (COC) and Field quality control and quality assurance (QAQC) procedures.

The core was delivered directly from the drill to a secure core logging facility near the drill site.  There the core had preliminary geoteching, including washing, metre marking and geological logging and sample marking procedures completed.  During the sample tagging process tags for prepared field standards from licensed suppliers and blanks comprised of washed cement quality silica sand were inserted approximately every 23 samples.   Field blanks were also inserted after any highly sulphide mineralized intervals.

The core was then delivered daily to Renaissance’s secure core processing facility in Kamloops B.C. by canopied pickup trucks.  Once there the core had additional geotech procedures completed including basic reassembly, loss location and estimation, and imaging.  The core was then sampled, depending on its durability to minimize loss by saw cutting, or splitting while maintaining a fast as possible sample processing speed.   Great care was taken to make the sampling as representative as possible.

The core samples were transported from Kamloops by Greyhound Courier directly to Acme Analytical Laboratories Ltd. in Vancouver for gold by fire assay AA finish and 36 element ICP-MS analyses from a 15 gram digested subsample.

3D spatial accuracy was maintained by surveying the area drilled using a hand held GPS.   The holes were also down hole surveyed with a Flexit multishot tool taking readings at about every 30 metres (100 foot) intervals.

Additional information will be released as results are received.
