- Gold and Silver
- 3 kilometres north of the town of Hawk Junction (20 kilometres northeast of the town of Wawa) in the Corbiere and Esquega Townships of Northern Ontario. The property has year-long road access as well as easy access to other infrastructure including rail, road, electrical power, labour force and suppliers.
Property Size Land Position:
- 18 contiguous patented mining claims covering approximately 285 hectares
Stage of Exploration:
- Early Exploration
- Binding LOI with Noble Mineral Exploration Inc. to acquire 100% interest in the Holdsworth property (part of the land package that comprises MacDonald’s Wawa-Holdsworth Project).
- 1.5% net smelter return royalty to Noble Mineral Exploration Inc. on the Holdsworth property only.
Historic work by previous operators defined three gold targets on the Wawa-Holdsworth Project:
- Greenstone-hosted quartz-carbonate vein deposit (Soocana Vein System);
- BIF-hosted gold deposits (gold-bearing pyrite zones in an Algoma-type iron formation);
- Gold-bearing Oxide Sands developed from the weathering of the auriferous Pyrite Zones.
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. 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. Preliminary metallurgical testing conducted by previous operators on composite samples recovered, without crushing, between 69% and 98.7 % gold.
MacDonald Mines has identified the Oxide Sands as a short-term target for gold production and is anticipating that additional Oxide Sands zones can be discovered along the 2 km strike length of the pyritize iron formation defined so far on the property.
2017 Work Program:
- MacDonald Mines initiated a core sampling program from the 2008 Drill Program. The Company is developing a database of the lithological and geochemical signatures associated with high grade gold assays at the Wawa-Holdsworth Project by utilizing XRF, magnetic susceptibility and SWIR measurements.
- The Company launched a trenching program to map and confirm the oxide sands' strike length and thickness. MacDonald Mines is also conducting a systematic sampling of the oxide sands over its total strike length.
- A bulk sampling program of the oxide sands was initiated in March 2017. 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.
- In April 2017, 100 kg of oxide sands were shipped to SGS Minerals Services to conduct metallurgical testing and investigate potential simple processing methods to concentrate the gold and silver from the Oixde Sands and achieve the highest possible recovery.
- 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.
