Valuation Commentary: MacDonald Mines Exploration Ltd. (TSX-V: BMK) (US Listing: MCDMF) (Frankfurt: 3M72) Wawa-Holdsworth Gold Project is located 25 km NE of Wawa Ontario, Canada, uniquely positioned proximal Argonaut's >6Moz Au Magino deposit property, and Richmont's >1Moz Au Island Gold Mine, along an underexplored extension of the prolific Michipicoten Greenstone Belt. The risk-reward characteristics are highly advantageous for investors establishing a long position in BMK.V as the current market cap (~$11.4M Canadian, trading at ~19 cents/share) relative to the inherent value of MacDonald Mines' Wawa-Holdsworth Gold Property appears disproportionate; near-term share price catalysts exist as the Company is aggressively exploring to build on known gold values and leverage its exploration teams expertise and experience in the Wawa district gold camp.

 

 

Fig. 1 Location Map of MacDonald Mines' Wawa-Holdsworth Gold Project - Within a few km of impressive gold deposits of miners whose deposits keep growing, and mills. There is road access to the property, it is close to power, rail, and a stable workforce, in a mining-friendly region.

 

The Wawa-Holdsworth project is proximal to the crustal-scale Wawa–Hawk Lake–Manitowik Lake Fault and encompass a 500 metre-wide deformation zone where gold was concentrated in different structures. These includes the Pyrite Zones, source of the gold-bearing Oxide Sands, the Soocana Vein System and the Golden Goose Shear Zone.

Oxide Sand Zones offer a quick pathway to cash flow:

 

Voluminous gold-bearing oxide sand (black sand) zones near surface have demonstrated potential for an immediate pathway to production/cash flow; e.g. 3.45 g/t gold and 29.99 g/t silver average grade from a composite of 23 panels, with preliminary metallurgical testing resulting in between 69% and 98.7% gold recoveries (without even crushing). The exploration team is now undertaking a program of mapping and quantifying these zones which were previously not mapped well and historically ignored for gold but characterized in the early-1900's as one of the best massive sulphide deposits in the country. There is the possibility of a 2.2 km strike length of gold laden Oxide Sands Zones over the auriferous iron formation (which acted as a trap for gold circulating in the system).

 

Company intends to extract 50,000+ oz Gold from oxide sands:

 

On March 30, 2017 the Company announced 100% ownership via LOI of the Wawa-Holdsworth Gold Project with terms that point to an imminent production scenario; aside from 5.5 million shares of BMK.V issued (along with equal warrants exercisable at $0.30 -- something we like to see as the belief is share price of BMK.V will rise substantially) and a partially repurchasable 1.5%NSR, the bulk of the principle consists of MacDonald Mines paying the equivalent of 5,000 ounces of gold equivalent to Noble once MacDonald has extracted, refined and sold a minimum of 50,000 ounces of gold from the oxide sands portion of the Property.
 

In brief, the oxide sands are the cap of the pyrite prospect on the property, which to date is just over 2,200 metres long and has a defined historic (non NI 43-101) resource of sulpher but never tested for Gold until 1988 (it was noted to have gold in it from trace to over 8 g/t, however no assaying was done for silver at the time). 43-101 compliant drilling in 2002 covered 332 m of strike length (of the 2,200 m); within that known length and extrapolated for tested widths + estimated depth we get sizeable tonnage of apparent ~3.45 g/t Gold (average grade tested) and ~29.99 g/t Silver (average grade tested) ready for the taking. Extrapolating that known 332 m length (x ~6) over the 2,200 m there appears 146,000 tonnes of such material for the taking in the initial strike set. The average depth based on historic drill holes would be much larger as far as surface extraction goes. The assumption on a parallel and multiple sets of sulphide sands is valid and has been proven in drill holes -- this rationalizes 550,000 to 675,000 tonnes (not yet NI 43-101, but the science is there to more than support an ~81,700+ ounce Gold equivalent target), most of which can be self financed from production that appears to require little capex at all to begin. Neither aggregate licencing nor bulk sampling permissions will be required for the extraction of the oxide sands on the Wawa-Holdsworth Project.

The Pyrite Zones are believed to contain multiple Gold-laden Oxide Sand Zones; e.g. drill core sample taken by Falconbridge Nickel Mines Ltd. (Band, 1983) was reported to contain 0.35 oz/ton, Au across 1.5 meters. Another sample from this hole taken from a pyritic shear in the hanging-wall six (6) meters above the Pyrite Zone was assayed four times yielding a range of assays from 0.24 to 0.51 oz/ton, Au.

  

At present, five related zones have been confirmed, thus >four times that above number (>675,000 tonnes = ~72,800 oz Gold, ~633,700 oz Silver* non NI 43-101 = ~81,700 oz Gold Equivalent (using US$17/oz Silver and US$1,200/oz Gold conversion) on parallel and multiple sets which have been proven in drill holes.

Oxide Sands can be treated like aggregate. Visible in the images of black oxide sands (seen in Fig. 2 above) taken from the property is gold and some course grain quartz (which likely also contain gold). The oxide sand zones appear amenable to MacDonald Mines simply obtaining a permit for mining aggregate; backhoe the material, then crush and ball mill the material (to maximize recoveries), and transport the floured material to one of the several mills located within a few kilometers of the property. Works programs underway this winter and spring 2017 are geared towards affirming a voluminous and robust understanding of these Oxide Sands Zones -- the potential for substantial share price appreciation from current price levels appears in order as exploration findings/results affirm what is suspected.

 

Bulk sampling/trenching on Oxide Sands to commence Spring 2017:
In 2002, the Oxide Sands were sampled over 332.5 metres along strike. They were reported to reach a depth of at least 8 metres and contained an average gold grade of 3.45 g/t and an average silver grade of 29.99 g/t. The objective of MacDonald's trenching program is to confirm the Oxide Sands' strike length and thickness and to undertake a systematic sampling of the mineralized horizon over the total strike length.

 

Excerpt of MacDonald Mines March 21, 2017 release regarding bulk sampling:

 

MacDonald Mines Prepares for 2017 Bulk Sampling Program at its Wawa-Holdsworth Project

 

TORONTO, ONTARIO--(Marketwired - March 21, 2017) - MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) ("MacDonald Mines" or the "Company") announces that it is initiating a bulk sampling program of the oxide sands at its Wawa-Holdsworth Project. The Company also announces that, following consultations with Ontario's Ministry of Natural Resources and Ministry of Northern Development and Mines ("MNDM"), neither aggregate licencing nor bulk sampling permissions will be required for the potential extraction of the oxide sands on the Wawa-Holdsworth Project.

 
The Wawa-Holdsworth property is comprised of fee simple absolute patents carrying both mineral and surface rights which make them exempt from MNDM exploration plan and permit requirements. The property is also located in an area which is currently not subject to designated licensing requirements under the Aggregate Resources Act. This will help to expedite preparation for potential extraction as the Company now drafts a closure plan.

 
About the Oxide Sands

 
The Holdsworth Pyrite prospect is a gold and silver bearing, black colored, "oxidized cap" ("oxide sands") that overlies a massive pyrite zone. The five confirmed zones (the 'East', 'East Extension', 'East Offset', 'West' and 'West Offset') have a combined strike length in excess of 2,200 metres (Algoma Steel Corp. and the Grasseli Chemical Co.). The actual width of the underlying pyrite zone has a range of 2 to 10 metres. In several test locations, the oxide sands were reported to reach a depth of over 8 metres.

 
The oxide sands are one of the main gold targets on the property. MacDonald Mines' current trenching program is mapping and confirming the oxide sands' strike length and thickness. The Company is also conducting a systematic sampling of the oxide sands over its total strike length. During the 1988 exploration program, sampling from the red, yellow and grey soil above the oxide sands was found to contain elevated gold values, ranging from trace to 0.206 oz/ton, gold. This surface material will also assist in delineating the extent of the oxide sands.

 
Potential Extraction of the Oxide Sands

 
The soft and relatively unconsolidated oxide sands material can be easily excavated with a backhoe and appears to be amenable to being extracted like an aggregate. The area's shallow overburden, the proximity to labour and equipment and the easy access to the site should result in very inexpensive mining costs should the Company delineate a large enough deposit. A sampling program of the oxide sands conducted in 2002 produced an average grade of 4.03 g/t gold and 30.89 g/t silver. Preliminary mill testing by normal vat leach processing without crushing or other processing resulted in a 94 % gold recovery (Seymour M. Sears, P. Geo., 2002).

Excerpt of MacDonald Mines April 5, 2017 release regarding metallurgical testing:

 

MacDonald Mines Begins Metallurgical Testing of the Oxide Sands at its Wawa-Holdsworth Project

 

TORONTO, ONTARIO--(Marketwired - April 5, 2017) - MacDonald Mines Exploration Ltd. (TSX VENTURE:BMK) ("MacDonald Mines", or the "Company") has shipped approximately 100kg of oxide sands to SGS Minerals Services to conduct metallurgical testing and investigate potential processing methods for the Wawa-Holdsworth Pyrite prospect.

The Wawa-Holdsworth Pyrite prospect is a gold and silver bearing, black coloured, "oxidized cap" ("oxide sands") that overlies a massive pyrite zone. The strike of the pyrite zone runs over 2 km and its thickness ranges from 2 to 10 metres. The oxide sands reach a depth of more than 8 metres. A sampling program of the oxide sands conducted in 2002 produced an average grade of 4.03 g/t gold and 30.89 g/t silver. Preliminary mill testing by normal vat leach processing without crushing or other processing resulted in a 94 % gold recovery (Seymour M. Sears, P. Geo., 2002).

The metallurgical testing initiated by MacDonald Mines will investigate simple processing methods that require no chemicals to concentrate the gold and silver and achieve the highest possible recovery.

To evaluate multiple options the following will be completed:

  • Head assays;

  • Mineralogical characterization of the feed;

  • Bond ball mill grindability test;

  • Heavy liquid separation testing;

  • Knelson Concentrator testing;

  • Flotation and leach testing on gravity tailings as diagnostic tests.

Quentin Yarie, MacDonald's President and CEO commented: "In the few months our team has worked on the Wawa-Holdsworth Project, we've already initiated a bulk sampling program of the oxides sands, initiated metallurgical test work on the immediate gold target on the property and secured a 100% interest in the property. Following spring breakup, the Company will ramp up its sampling program to better define the oxide sands and continue to prepare for their potential extraction."

Fig. 3 (below) Wawa-Holdsworth Gold Zones -Three styles of gold mineralization exist on the original 285 hectares Wawa-Holdsworth project (the Company has since added 84 claims of similar ground nearby), all part of the same gold system within the 500 metre-wide deformation corridor:

 

"*" in the image above signifies non NI 43-101 compliant values for the Soocana Vein.

 

The three gold mineralization styles on the property (and shown in the claims map above) are:

  1. An oxidized cap at surface developed over a massive pyrite zone (Algoma Iron Formation) -- "The Oxide Sands",

  2. The precursor to the Oxide Sands - a massive pyrite zone (Algoma Iron Formation) at depths -- "The Massive Sulphide", and

  3. Lode Gold in traditional quartz veins -- "The Soocana Vein".

Large near-term exploration upside potential - Oxide Sands, BIF, and Load Gold Vein

 

The exploration team has learned from other projects in the area that the alteration system associated in this land package is very large, something that people historically either didn't recognize, or know about, or chose to ignore, instead they would focus on the quartz veins. Banded Iron Formations (BIF) are hosted on the property, similar to other formations that were historically mined near Wawa. We know that when you put these type of rocks in an environment where gold bearing fluids are circulating they form very good traps for gold, and we know that BIF on this property are mineralized because the Oxide Sands are derived from the weathering of those banded formations. Additionally, localized drilling and samples in BIF have shown them to be gold bearing, historic samples were upwards of ~0.3 ounces/t.

 

Lode Gold in traditional quartz veins -- "The Soocana Vein": Almost all the historic drilling and work done for gold on the property was concentrated into a 700 m strike length associated with this 'Soocana' vein with very little efforts put into other gold plays on the property, apart from the Oxide Sands. The Soocana vein system is a shear zone with stacked auriferous quartz veins. A poor understanding of the shear system geometry by previous operators is obvious as drilling occurred in every direction with un-systematic sampling practice. Noteworthy historic (non NI 43-101 compliant) drilling intersections include 16g/t gold over 4.3 m, and 6.9 g/t gold over 15.8m and demonstrates the potential.

 

Figure 5 (below) Surface Mining Plan of Soocana Vein from November 15, 1933 - From the then Soocana Mining Company. There were plans at one point to exploit the robust gold and silver values of the vein. At the time, the Soocana Mining Company Limited calculated a gold resource (historical non NI43-101) of 54,000 tons of material grading 0.556 oz/t (19.06 g/t), however the Soocana Vein was never meaningfully mined in any way, only a small pit scratched the surface in one spot from earlier on.

On February 28, 2017 MacDonald Mines announced that it has begun a core sampling program at its Wawa-Holdsworth Project. The Company has begun a systematic analysis of core from the 2008 Drill Program. It is developing a database of the lithological and geochemical signatures associated with high grade gold assays by utilizing XRF, magnetic susceptibility and SWIR measurements. Initial observations found that the highest grades of gold are associated with deformed quartz-iron-carbonate veins, with additional sericite, chlorite and tourmaline alteration, hosted in mafic metavolcanic rocks. These veins locally contain visible gold, accompanied by chalcopyrite, galena and pyrite mineralization. The Company will be assaying any previously un-sampled prospective zones, particularly those containing significant shearing and quartz-iron-carbonate veining, and re-sampling any significant quartz veins and analyzing them using metallic screening. Highlights from the 2008 Drill Program include:

28.35 g/t gold over 1.07 m
17.9 g/t gold over 0.54 m
13.5 g/t gold over 0.66 m
4.07 g/t gold over 0.95 m
4.03 g/t gold over 0.90 m

Proven exploration team that understands area geology: One of the most effective investment techniques for generating superior returns in exploration mining stocks is to follow quality/proven people to new ventures. The advisory and exploration team for MacDonald Mines has enjoyed exploration success in the Wawa gold camp (e.g. another mining Company just raised ~$6M off the success of their exploration efforts on a neighboring property). For example, Dr. Jean-Philippe Desrochers ,Ph.D., P.Geo., is part of the MacDonald advisory/exploration team (Dr. Desroches is also currently the QP for Osisko) -- he was Vice-President of Exploration at the Windfall Lake Gold Project (now owned by Osisko Mining) in its early days from 2005 to 2010 (then Murgor), and became Eagle Hill's Chief Geologist in 2010 before becoming Vice-President Exploration for Eagle Hill in 2013. Under his watch from 2005 - 2013 he took the Windfall gold project from conceptual to advanced stage with impressive resource that resulted in the Osisko buy-out. The advisory and exploration team of MacDonald Mines is looking to replicate that type of success here on the Wawa-Holdworth property now and believe their success in the area and intimate understanding of the geology provides a level of insight and expertise that was never previously afforded this prime land package.

 

Plans - Winter-Spring-2017 works program:

 

There are many gold structures that are present on the property and the exploration team knows that the structures control the gold so the first order of business is to get a handle on them with geophysics this winter and map them all. The exploration team will pick targets, do trenching to test the Oxide Sands, expose structures, and perform channel sampling. The goal will be twofold; 1) lead to drilling load-hosted/shear-hosted structures highly prospective for significant discovery, and 2) to quantify the potential of the gold laden Oxide Sands for a short-term path to production which could finance the Company in exploration (non-dilutively) going forward and reward shareholders establishing a long position now.

 

The Company is topped up, and able to meet near-term exploration objectives. The area is hot, area miners keep growing their deposits, and the property has already yielded exceptional grades in different mineralization styles -- showing the potential of what we can expect in what is shaping up to be one of the most exciting exploration plays in North America this 2017.

Wawa-Holdsworth Gold Zones

 

Three styles of gold mineralization on the Wawa-Holdsworthproject -all part of the same gold system within the 500 metre-wide deformation corridor.

  1. Greenstone-hosted quartz-carbonate vein deposit (Soocana Vein System);

  2. BIF-hosted gold deposits (gold-bearing pyrite zones in an Algoma-type iron formation);

  3. Gold-bearing Oxide Sands developed from the weathering of the auriferous Pyrite Zones.

Most of the property outside the Soocana Vein and the center of the defined Oxide Sands Zones remain under-explored

 

Fig. 10 (right) Gold Zones

 

BIF-hosted gold mineralization (gold-bearing pyrite zones in an Algoma-type iron formation) was the earliest discovery on the property.

  • It was sparsely drilled for gold (7 exploration holes, un-systematic sampling).

  • Into a shear zone with penetrative deformation and strong alteration.

  • Gold mineralization inside pyrite, but also in sheared zones above and below sulfide horizons.

  • Prospective strike length of 2.2 km – Oxide Sands are derived from the BIF formation.

Fig. 11 (right) Auriferous and Pyrite-rich Algoma-type Iron Formation

 

Oxide Sands Zones are mapped over a 610 metres strike-length.

 
Of that, detailed sampling of panels sampled was done over a 332 metres strike length whereas the remaining zones were poorly defined and not systematically sampled.

 
Possible extensions over the entirety of the 2.2 km strike length of the auriferous and pyritic iron formation.

 
These extensions of the Oxide Sands remain to be proven and defined.

 

Fig. 12 (right) Oxide Sands shown in yellow.

 

  

Fig. 13 (above) Oxide Sands

 

The Oxide Sands are one of the main gold targets on the property. Gold mineralization occurs in black sands composed of fine quartz, non-magnetic iron oxides (likely oxidized pyrite) and free gold. The Oxide Sands are interpreted to be derived from the weathering of an auriferous and pyritized Algoma-type iron formation. The pyritized iron formation is, so far, traced on the property over a 2 km-long strike length.

 

In 2002, a detailed and systematic sampling of the Oxide Sands was conducted over a strike length of 332.5 metres (Blocks A and B). The mineralized sands reached a depth of at least 8 metres and contained an average gold grade of 3.45 g/t and an average silver grade of 29.99 g/t.

The Pyrite Zones are believed to contain multiple Gold-laden Oxide Sand Zones:

 

The Pyrite Zones are a pyrite-altered Algoma-type iron formation and represent a iron formation-hosted gold target. Algoma-type iron formation are recognized hosts of large gold deposits in Canada and the United States. Key examples of gold deposits in Algoma-type iron formation in Canada the Meadowbank, Meliadine and Musselwhite gold deposits (Dubé et al., 2015). The pyrite Zones forms steeply dipping east-west trending lenses distributed along a mafic/felsic metavolcanic contact over a defined strike length of 2.2 kilometres. A gold intersection of 5.18 g/t gold over 1.5 metre were also obtained in a sericite-altered shear zone in the hanging wall of the pyrite zone whereas a 1988 drilling intersection in the pyrite contains 0.85 g/t over a 11.83 metres. This appears to be similar to the Bousquet deposit (see below) taken from 1917 report on the property which identified a historic (non NI 43-101) sulphide resource.

 

The Holdsworth Pyrite Prospect consists of massive lenses of pyrite situated at the contact between mafic and felsic metavolcanic rocks. These lenses trend approximately east-west and dip steeply towards the north. They are locally cut and offset by north-northwest trending faults. At present, five related zones have been confirmed by surface stripping and prospecting and several others indicated by ground geophysical surveys. The five confirmed zones (the 'East', 'East Extension', 'East Offset', 'West' and 'West Offset') have a combined strike length in excess of 2200 meters. Two drill programs completed from 1918 to 1926 (Algoma Steel Corp. and the Grasseli Chemical Co.) identified an iron reserve of 1,019,273 tons of 46 % sulphides within what is herein referred to as the East Pyrite Zone.
 
 
The pyrite zone has been intersected in 6 holes in more recent exploration programs including 2 holes by Falconbridge in 1983 and 4 by Reed Lake Exploration Ltd. in 1988. The Holdsworth Pyrite zones are of interest for their gold potential for two reasons. One of these is represented by the unoxidized portion of the sulphide zone and it's surrounding rocks. A drill core sample taken by Falconbridge Nickel Mines Ltd. (Band, 1983) was reported to contain 0.35 oz/ton, Au across 1.5 meters. Another sample from this hole taken from a pyritic shear in the hanging-wall six (6) meters above the Pyrite Zone was assayed four times yielding a range of assays from 0.24 to 0.51 oz/ton, Au. The massive pyrite typically contain up to 5% sugary to greasy quartz stringers and ribbons similar to the black sands. The massive pyrite contained gold values ranging from nil to 0.14 oz/ton. Three of the five holes drilled by Reed Lake Exploration Ltd. were found to contain very anomalous gold values: 1.03 g/t Au over a core length of 2.13 meters (Hole R23); 3.06 g/t over 6.1 meters (Hole R26) and2.08 g/t Au over 5.8 meters (Hole R27).
 

The second zone of interest on the Holdsworth Pyrite prospect is a gold and silver bearing, black colored, "oxidized cap" that overlies the massive pyrite. This coarse sandy material is in excess of eight (8) meters thick in most locations, where sampled, and contains gold values ranging from a few parts per billion to a high of 14.2 g/t (0.41 oz/ton).
 

The oxidized material that forms a "cap" to the Holdsworth Pyrite deposit has been described by old-time prospectors as a 'black sand'. It consists of siliceous grains and non magnetic iron oxide pellets ranging from a few centimeters to several microns in size. It is assumed to be the oxidized equivalent of the underlying massive iron sulphide. The sulphide zones are frequently anomalous in gold. Assays from a number of drill holes (Band, 1983; Sears, 1989) have ranged from nil to 0.056 oz/ton, Au. The best intersection to date was from Hole R26 (Reed Lake Exploration, 1988) which contained a 6.1 meter (20 foot) section assaying 1.06 g/t (0.031) oz/ton, Au. The enriched gold values in the overlying material are assumed to be related to the oxidizing and weathering process.
 

In 1988, Reed Lake Exploration Ltd. carried out a stripping program over parts of the East and West Pyrite Zones (Figure 4). In the early part of the program, the overburden was stripped completely down to the black, oxidized granular material. When it was discovered that the overlying red and yellow soil was also highly elevated in gold, the remainder of the stripping stopped just below the overlying bouldery till. Sampling was then carried out by means of surface channels at regular intervals across the zone (Appendix 1). Two blocks within the East pyrite zone in which the oxidized cap was exposed yielded assays ranging from trace to 0.284 oz/ton, Au and an average grade of 0.208 oz/ton, Au. The sampled width averaged 2.9 meters (9.5 feet) for a strike length of approximately 100 meters (328 feet). The actual width of the underlying pyrite zone has a range of 2 to 10 meters (6.5 to 33 feet). In several test locations, the bottom of the zone was not reached at a vertical depth of 8 meters.
 

During the 1988 program, sampling from the red, yellow and grey soil above the black oxidized zone was also found to contain elevated gold values, ranging from trace to 0.206 oz/ton, Au. This material extends throughout the area stripped, so it was assumed that the black granular oxide occurred beneath it at shallow depths. A very limited amount of stripping was completed on the West Zone to check for the existence of the oxidized cap material. Six (6) grab samples were collected from two three meter sections across this zone. Four of these consisted of brown soil and contained trace amounts of gold. The other two were of black-green material and contained 0.052 and 0.064 oz/ton, Au.

 

 

Fig. 14 (above) Oxide Sands - A total of 340kg of material from the Black Sands Zones was sent to SGS Lakefield for metallurgical testing in 2009. Preliminary metallurgical testing of the oxide sands resulted in gold recoveries between 69% and 98.7% via 48 hours agitated cyanidation without crushing.

 

Load-Gold, Greenstone-hosted quartz-carbonate vein deposit (Soocana Vein System)

 

Soocana vein system – Shear zone with stacked auriferous quartz veins
 

Except for the Oxide Sands, almost all the historic drilling and work done for gold on that property was concentrated into a 700 metres strike length associated with this vein with very little efforts put on the others gold plays of the property.

 
 

 
Overall the property remains underexplored.
