Newman Madsen - 2011 Project Update
Newman-Madsen is one of the Company's early stage exploration projects in Ontario and is held in a 50/50 joint venture with Premier Gold Mines with Sabina as the operator.
The rock units underlying Newman-Madsen property are considered to be very prospective in that all of the key features for high-grade mineralization in the Red Lake belt can be found on the property. These units are locally cut by northwest-trending structures, making them especially attractive where coupled with elevated gold and arsenic geochemical signatures.
The property is underlain by Archean rocks of the Red Lake greenstone belts consisting of the Mesoarchean Balmer assemblage in the northern portion of the property and the Neoarchean Confederation assemblage to the south. The assemblages are separated by a regional unconformity which has been identified in close proximity to numerous high grade gold deposits in the Red Lake area, including the Madsen, Campbell and Red Lake mines. This regional unconformity crosses the south-southeastern sector of Newman-Madsen property over approximately 1.6 km where it remains largely untested at depth. The Madsen Mine situated along trend to the Southwest historically produced >2.4 million ounces from an underground mining operation.
Newman-Madsen work in 2010/2011 was organized into a two phase $1.09 million drilling program with 50% of the cost borne each by Sabina and Premier.
Phase 1 consisted of four holes totalling 3,183 metres of drilling to test the north eastern extension of the Madsen Mine stratigraphy at levels significantly deeper than previously explored.
Drilling was successful in intersecting the targeted stratigraphy and delineating a highly prospective area of hydrothermal alteration where significant gold values including a high-grade intercept of 43.51g/t over 0.65 meters were encountered.
The intercept is interpreted to demonstrate the potential for the Newman-Madsen property to host significant mineralization consistent with the recognized horizons hosting the Madsen Mine (>2.4 million ounces) located immediately to the Southwest.
Further anomalous and significant gold assays were also returned from a series of quartz-feldspar porphyry intrusives that are a part of ongoing interpretations and follow up exploration. Phase I mapping and core re-logging has also been completed increasing the geologic confidence within the property while further defining exploration targets.
Phase II exploration of the Neman-Madsen property commenced in early 2011with diamond drill testing of a diverse group of high priority targets generated through the incorporation of newly derived and historic data that has been coupled with developing geologic interpretations throughout phase I exploration. A series of ten holes, totalling approximately 3000 meters was implemented to test this series of targets. The targeting focused dominantly on interpreted folded mafic and ultramafic rock sequences of the Balmer Assemblage where coincident with favourable D2 structures, geochemical signatures, and resistivity anomalies. Results of this drilling is still being interpreted. These targets are elected to present opportunities to intersect mineralization reflecting in similarity to the Red Lake Mine High-Grade Zone style.
Golden Sidewalk - 2008 Property Update
The Golden Sidewalk and Skinner projects are adjacent projects, both are located approximately 70 km East Northeast of the town of Red Lake, Ontario. Both projects are located in the northwest quarter of Skinner Township, Kenora-Red Lake Mining Division, Ontario. The Golden Sidewalk project lies north of the Skinner project. The property hosts several mesothermal quartz vein hosted gold showings. The historic Bathurst Mine was developed on one of the veins. The Golden Sidewalk property consists of a contiguous group of 12 leased claims and 6 staked claims and is 100% owned by Sabina Silver Corp.
The property is underlain by pillowed, spherulitic, and massive mafic flows together with irregular and ill-defined areas of gabbro. These latter areas may represent coarser grained core regions of massive flows, or alternatively truly intrusive material. The metavolcanics are flanked on the west by trondhjemite of the Trout Lake Batholith, and locally by an ultramafic. metavolcanics and gabbroic rocks of the central and eastern parts of the property are cut by numerous felsite bodies, most of which clearly transect stratigraphy at about 090-120°. A second set exhibits an approximately north-south strike, roughly conformable to stratigraphy.
From November 2007 through March 2008 twenty-three holes, totalling 7,863 m, were drilled on the property. The holes tested the depth and strike extension of the historic Bathurst Mine Horizon. The program was intersected gold mineralization in the primary target Bathurst Mine Horizon and also discovered a second gold bearing mineralized horizon, including 45.96 g/t Au over 1.70 meters. Diamond drilling of the Bathurst Mine Horizon and the new Upper Bathurst Mine Horizon confirmed the presence of multiple gold bearing structures. Exploration potential exists along strike and at depth.
Skinner - 2008 Property Update
The Skinner and Golden Sidewalk projects are adjacent projects, both are located approximately 70 km ENE of the town of Red Lake, Ontario. Both projects are located in the northwest quarter of Skinner Township, Kenora-Red Lake Mining Division, Ontario. The Skinner project lies south of the Golden Sidewalk project. The property hosts several mesothermal quartz vein hosted gold showings.
The Skinner property consists of a contiguous group of 19 staked claims. Sabina holds 100% ownership subject to the following royalties and carried interests. Premier Gold Mines Ltd. holds a 7.5% net profit interest (capped at $450,000). Newmont Canada holds a 1% net smelter return royalty. A local prospector holds a 2% net smelter return interest (1% of which can be purchased by Sabina for $1,200,000, while the other 1% is subject to a right of first refusal granted to Sabina).
The claim group is underlain by rocks of the Balmer Assemblage in the extreme southern portion of the property and the Narrow Lake Assemblage in the remaining portion of the property. The property consists predominantly of massive to pillowed, locally variolitic basaltic komatiite to basaltic flows. Minor interbedded clastic to possibly cherty sediments have also been noted as minor metre-scale to ten's of metre-scale banded units within the massive and pillowed flows. These units have been extensively intruded by concordant to sub-concordant massive to weakly foliated gabbroic sills. Minor feldspar +/- quartz-phyric sills or dykes occur in the central and southern portions of the property. All units are generally ESE to east trending with facing directions indicating tops to the north. Calc-alkaline basaltic andesitic to rhyolitic fragmental units as well as minor tuffaceous siltstone and massive, fine to medium grained, locally moderately foliated and amphibolitized basaltic flows of the Balmer Assemblage occur in the extreme southern portion of the property.
A number of gold occurrences (Dunkin Prospect, Tie Line Showing, Vihonen Showing) are located on the property and generally these are spatially associated with the concordant to sub-concordant gabbroic sills.
Drilling in 2008 on the Skinner Property intersected a gold mineralized shear zone developed along the contact between a gabbro sill and an underlying ultramafic unit. The newly discovered ultramafic unit is located under an arm of Narrow Lake. At present, only two holes have tested the mineralized structure, both returning anomalous gold values, including 4.97 g/t over 0.75 m, 1.29 g/t over 0.70 m and 1.28 g/t over 0.30 meters . These two holes were successful in discovering gold mineralization in a broad east-west trending shear zone; now called the "Blind Zone". Gold mineralization is associated with up to 3% pyrite and arsenopyrite.
