inwood Dolomite

Magnesium-rich Dolomite

The Inwood Magnesium Dolomite Property is located in south-central Manitoba, 80-km north of Winnipeg. The Property covers 1,583 hectares (3,914 acres) holding near or at surface beds of high-purity dolomite that are above the water table. The Property hosts a substantial resource identified in a National Instrument 43-101 resource report. The current focus of the Project is the identification of viable markets for high-purity dolomite.


Gossan also holds 3 additional claim blocks in the area totaling over 4,400 hectares. These Northern Claim Groups also hold near or at surface beds of dolomite that are above the water table.


On November 16, 2016, Gossan announced that it had entered into an Exclusive Supply Agreement with Sediment Research & Minerals Ltd. (“SRML”) to be its sole provider of high-purity dolomite. SRML has identified several markets for dolomite and also has access to Akwaton®, a trademarked synthetic polymer, and other polymers. These polymers have a number of applications that require high-purity dolomite.


Under the terms of the exclusive supply agreement, Gossan will receive a production royalty on all dolomite sold to SRML of $1.00 per tonne for products with a price of less than $70 per tonne and a royalty of 2% for products with a price of $70 per tonne or greater. Gossan will also retain an equity interest in any project.


Sediment Research & Minerals Ltd (SRML) is a Manitoba-based, privately-owned, “green” company. SRML intends to utilize its proprietary processes to develop a set of high-value by-products. Markets for these innovative specialty products potentially include agriculture, aquaculture, human & animal healthcare, mineral development & tailings remediation and wallboard construction.


On February 14, 2017, Gossan received approval to access, explore, and extract up to 10,000 tonnes of dolomite from a proposed test quarry.


On May 12, 2017, Gossan received a legal survey which it conducted on the Ant claim and the 2 quarry leases therein, to advance the development of the dolomite project.


On May 13, 2006, the Gossan completed a 27-hole drill program, totaling 496 metres, on its Inwood Magnesium Dolomite Property. Watts, Griffis McQuat (WGM) were retained to undertake a National Instrument 43-101 Report resource calculation based on the results from the 2006 drill program and 25 holes previously drilled on the Property.


The 2006 drill program was conducted at a grid spacing of 200x200 metres over an area of approximately 80 hectares. The program targeted the Fisher Branch Formation which typically outcrops at surface and extends to a depth of about 12-15 metres. Some of the holes also investigated the underlying Upper and Lower Stonewall Formations down to a depth of about 25 metres.


On September 8, 2008 Gossan announced the findings of the Watts, Griffis, McOuat National Instrument 43-101 Report (Final) on the Inwood Dolomite Project. The final report utilized a more sophisticated block modeling technique than an initial report. Total residue for the Fisher Branch resource was reduced to 0.34%.

The Inwood Property hosts a very-large, high-quality deposit with the report estimating the Fisher Branch resource as follows:

Formation and Zone Resource Classification Tonnage Grade MgO (wt%) Grade CaO (wt%)
Fisher Branch Measured 28,819,000 21.15% 30.91%
Fisher Branch Indicated 5,057,000 21.40% 30.66%
Fisher Branch Inferred 131,236,000 21.64% 30.51%


An initial environmental study has been conducted at the Inwood Property. No endangered species were identified in the assessment of the natural environment. The area provides typical habitat for garter snakes and grouse amongst other species, and alvar vegetation. Portions of the Inwood Property are part of a wildlife management area. The Fisher Branch resource is in an area of the property which is not within a wildlife management area.


Gossan contracted Jim Collinson, the former head of Canada's delegation to the OECD High Level Committee on Environment and Economy and the President of the UNESCO World Heritage Committee, to conduct a site visit at Inwood, which took place May 3, 2012 to study all environmental factors pertaining to the Inwood Property. Collinson made various recommendations to mitigate environmental concerns.


The Peguis First Nation has filed a Treaty Land Entitlement (TLE) in a large area in southeastern Manitoba which includes the Inwood area. Gossan has initiated an engagement process with the Peguis First Nation (PFN). The PFN is considered a pro-business band and their potential involvement could lead to additional support for the Inwood Project.


Between 2007 and 2013, the Company collaborated on the development of a new high efficiency magnesium metal production process being developed by Douglas J. Zuliani, known as the Zuliani Process. Despite considerable success in advancing the process and its development, the agreement with Dr. Zuliani expired in early 2013, at a time when considerable uncertainty developed regarding the outlook and future of the magnesium market. China produces about 85% of the world’s magnesium. As of January 1, 2013, China dropped its 10% export duty on magnesium ingot which resulted in a softening of magnesium prices. China is fully committed to remaining the world’s dominant magnesium producer.


Since the fall of 2015, Gossan has been collaborating with a third party, Sediment Research & Minerals Ltd. (“SRML”), to assess the quality and nature of the Inwood dolomite for various uses and applications. Over this period, testing was conducted on two dolomite samples in both Canada and Germany with positive results. SRML also has access to Akwaton®, a trademarked synthetic polymer. The polymer has a number of applications that require high-purity dolomite. SRML also has access to other polymers. On November 16, 2016, Gossan announced that it had entered into an Exclusive Supply Agreement with SRML to be its sole provider of high-purity dolomite. Gossan will receive a production royalty and also retain an equity interest in any project.
