Toronto, Ontario – April 6, 2017 – Noble Mineral Exploration Inc. (“Noble” or the “Company”)
(TSX-V:NOB, FRANKFURT: NB7, OTC.PK:NLPXF) has been advised that MacDonald Mines
(“MacDonald”) has begun metallurgical testing of the oxide sands at the Wawa-Holdsworth project. In the
MacDonald News Release dated April 5, 2017 MacDonald states that “It has shipped approximately 100
kilograms 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 two kilometres and its
thickness ranges from two to 10 metres. The oxide sands reach a depth of more than eight metres. A
sampling program of the oxide sands conducted in 2002 produced an average grade of 4.03 grams per
tonne gold and 30.89 g/t silver. Preliminary mill testing by normal vat leach processing without crushing or
other processing resulted in a gold recovery of 94 per cent (Seymour M. Sears, PGeo, 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 chief executive officer, 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 testwork on the immediate gold target on the property and secured a
100-per-cent 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."
Wawa-Holdsworth project highlights:
• Approximately 285 hectares, 20 kilometres northeast of the town of Wawa;
• Neighbouring Argonaut's greater-than-six-million-ounce gold Magino deposit and Richmont's
greater-than-one-million-ounce gold Island gold mine;
• Numerous gold showings with diversified mineralization styles occurring in a 500-metre-wide
deformation corridor;
• Year-long road access and easy access to rail, road, electrical power, labour force and suppliers.
