Holdsworth
Property Overview
Property Location and Ownership
The Holdsworth Property consists of 19 contiguous patented mining claims (the "Holdsworth Claims") covering some 304 hectares. Sixteen of these are located in the extreme southern part of Corbiere Township and the remaining three extend into the northern part of Esquega Township, Hawk Junction, District of Algoma, Wawa Area, Sault Ste. Marie Mining Division, Ontario.
The Holdsworth Property is the potential to host Gold and Silver mineralization within three (3) distinct geological environments namely:
- Lode Gold in traditional quartz veins -- "The Soocana Vein",
- An oxidized cap at surface developed over a massive pyrite zone (Algoma Iron Formation) -- "The Oxide Sands", and
- The precursor to the Oxide Sands - a massive pyrite zone (Algoma Iron Formation) at depths -- "The Massive Sulphide".
Ownership
Noble has recently disposed of its interest in the Wawa Holdsworth project for consideration totaling:
- 8,000,000 treasury shares of MacDonald Mines Exploration Ltd;
- 8,000,000 3 yr warrants of MacDonald (2.5mm exercisable at $0.15 per wt plus 5.5mm exercisable at $0.30 per wt);
- 10% gold streaming from production of the Holdsworth Oxide Sands up to 5,000 ozs. of gold;
- 1.5% NSR on the property (subject to a 50% buyback for $500,000)
The property has the potential to host Gold and Silver mineralization within three (3) distinct geological environments namely:
- Lode Gold in traditional quartz veins, known as the "The Soocana Vein",
- An oxidized cap at surface developed over a massive pyrite zone (Algoma Iron Formation) known as the "The Oxide Sands", and
- The precursor to the Oxide Sands - a massive pyrite zone (Algoma Iron Formation) at depths, known as "The Massive Sulphide".

"Highlights from MacDonald's initial sampling program include:
- The discovery of a new gold-bearing shear zone next to the old CN railway line (image 1) sample containing 5.36 g/t gold; and
- The Company (MacDonald) has determined that the known gold mineralized zones at Wawa-Holdsworth are part of a 500-metres wide corridor with multiple zones of deformation and hydrothermal alteration that are considered favourable for gold mineralization.
Quentin Yarie, MacDonald's President and CEO commented: "We are excited that with the limited time spent on the property since the announcement of the Option Agreement, our experience in the Wawa Gold Camp has led to the discovery of a gold-mineralized shear zone next to a railway line that has been used for decades. The observation of numerous deformation and alteration zones in a 500-metres wide corridor suggests that the gold system at Holdsworth is much larger than what previous exploration results indicate. Results to date are exciting and we are looking forward to further the development of this very promising project."
Results from the initial sampling program
This sampling and mapping program led to the discovery of a gold-bearing shear zone located alongside the old CN railway in the southern part of the property. The discovered gold-bearing shear zone is formed close to the contact between a volcanic sequence and a composite porphyritic intrusion. This sampling and mapping program also indicates that the previously known zones of gold mineralization of the Wawa-Holdsworth Project are part of a much larger deformation and alteration corridor that is now defined over a width of 500 metres.
The main zones of gold mineralization of the Wawa-Holdsworth Project include:
- Lode Gold in traditional quartz veins, known as the "The Soocana Vein",
- An oxidized cap at surface developed over a massive pyrite zone (Algoma Iron Formation) known as the "The Oxide Sands", and
- The precursor to the Oxide Sands - a massive pyrite zone (Algoma Iron Formation) at depths, known as "The Massive Sulphide".
The identification of this large deformation and alteration corridor, which already hosts many zones of gold mineralization, indicate that the gold system is likely larger than what is indicated by previous exploration and that additional exploration may uncover additional zones of gold mineralization.
MacDonald's future exploration programs at Holdsworth will take full advantage of its technical team's experience and expertise in the Wawa Gold Camp. This includes the use of forefront technologies like short wave infrared and portable XRF analyses that provide quantitative mineralogical and chemical indicators to evaluate the fertility and prospectivity of gold-bearing structures. The Company has also initiated a detailed review and re-interpretation of the existing exploration data on the property to pinpoint possible areas of gold mineralization that were missed in the past. This will help define the boundaries and size of the gold system present on the property, and guide future exploration programs.
2010
The Company intends to carry out a 2,000 meter auger drill program on the Black Sands Zone of the Holdsworth Gold Project. The purpose of the program is to quantify the gold/silver resource in the Black Sands surface zone as a follow up to the metallurgical testing recently completed at SGS/Lakefield Laboratories. Upon completion Hawk will be able to complete a resource estimate and commence to determine the technical feasibility and economic viability of the Black Sands Zone.
The auger-drill program is expected to commence sometime in the late summer/fall of 2010.
2009
The Company announced the final results (See NR 09-01-13) of its 34-hole, 5,498m drill program for the gold-mineralized Soocana Vein System on the Holdsworth Gold Property, Hawk Junction-Wawa Area, Northern Ontario. A total of 2,422 drill core samples were submitted to ActLabs in Thunder Bay for Au, Ag and 36 element ICP analysis.
Hawk also shipped an additional 90kg (see HUI NR -09-05-04) of Black Sands material from the 4 pit locations in the Black Sands Zone to SGS Labs, Lakefield, Ontario for additional metallurgical testing.
Holdsworth Project -- Drilling Results
The following are highlights of the results from Hawk's 34-hole drill program on its Holdsworth Gold Property.
*Bracketed values are Metallic Sieve Au analysis and check results using Metallic Sieve analysis.
Appendix A provides the comprehensive results for this 34-hole program, as well as information regarding the location, spacing and depth of each hole. As disclosed on Appendix A, the results from the holes that are not included in the preceding table returned no significant results.
Of the total of 340kg of material from the Black Sands Zones was sent to SGS Lakefield for metallurgical testing (see NR May 4, 2009)
Holdsworth Project: Black Sand Zone -- Pitting Program Results
Metallurgical studies are being conducted by SGS Group at their facility in Lakefield, Ontario. Preliminary results from those studies show that gold (Au) recoveries on the Black Sand material range from 69% to 90% in a 48 hours agitated cyanide leach test. SGS is an independent accredited analytical laboratory.
Initially, 4 individual samples (Sample 'A', 'B', 'C', & 'D') consisting of approximately 250kg that were extracted from the Black Sand Zone, were composited and demonstrated an average 69% Au recovery. When the samples were analyzed individually, recoveries were: Sample 'A' -- 89.8%, Sample 'B' -- 80.5%, Sample 'C' -- 45.6 % and Sample 'D' 80.3% Au respectively (see table below).
SGS/Lakefield recognized that Sample 'C' was a problematic sample and has since commenced additional tests on Sample 'C' such as an "ultra fine grind" and a "Diagnostic Leach Study" which utilizes a sulphuric acid leach to dissolve any coatings that may be on the gold mineralization followed by a cyanide leach, a hydrochloric acid leach to dissolve any oxides present, and finally a second cyanide leach. It is hoped that these measures will provide an indication of the gold metallurgy and help explain why the sample is not amenable to direct cyanide leaching.
Hawk plans to commence delineation and definition drilling using an auger or a sonic drill rig to quantify the gold and silver mineralization in the approximately 4400m of strike length of the 4m width and 8m depth of the Black Sand Zones this summer. As part of this program, Hawk will isolate and quantify separately, Sample 'C' type material which is known to exist over approximately 50m between Sample 'B' and Sample 'D', and then evaluate the need for additional testing.
