Northern Silica Corp. 100 % Indirect
All of the shares of Heemskirk Australia were acquired by Northern Silica Corp. (NSC) in July 2017.

Heemskirk Canada Limited is a wholly-owned subsidiary of Northern Silica Corp. (NSC)

On June 30, 2020, Northern Silica Corporation, Heemskirk Mining Pty. Ltd., Heemskirk Canada Holdings Limited, Heemskirk Canada Limited, Custom Bulk Services Inc. and HCA Mountain Minerals (Moberly) Limited (collectively, the “NSC Companies”) became subject to an initial order (the “Initial Order”) under the Companies’ Creditors Arrangement Act, RSC 1985, c. C-36, as amended (the “CCAA”). The Initial Order was granted by the Honourable Madam Justice K.M. Horner of the Alberta Court of Queen’s Bench. Pursuant to the Initial Order, Alvarez & Marsal Canada Inc., LIT was appointed as Monitor of the NSC Companies.

Deposit Type

  • Sedimentary


Summary:

The material that is mined at Moberly is the Ordovician Mount Wilson Quartzite unit. Near Golden it reaches a maximum thickness of 480 metres at Horse Creek (less in the mine area) and Mount Moberly is the northern limit of the unit, where it is terminated by a thrust fault. The quartzite is typically grey to buff coloured massive orthoquartzite with some evidence of crudely laminated and cross laminated beds near the base.

Bedding generally strikes around 118° magnetic and is vertical to steeply NE dipping. The rock consists of an orthoquartzite which is variably de-cemented (ie by removal of the silica ‘cement’ binding the grains) so that most of the mining area consists of ‘altered’ friable or ‘sandy’ quartzite to various degrees. There appears to be no systematic variation or control of the de-cementing. The composition of the rock is +99% SiO2 as quartz, with the remainder being silicate clays and very rare other silicate minerals.

Petrological studies show that the sand grains within the rock vary between 0.841mm to 0.105mm in diameter (20 mesh (#) to 100 mesh (#) on the US scale).

The only potentially economic mineralization observed within the map area is quartzite. The quartzite found on the property is a sedimentary deposit known as the "Wonah Quartzite", probably of Ordovician age and is found as two distinct members. The first is a friable quartz sandstone which comes in contact with limestone to the southwest in the area of the sand pit in the pre-existing Kathy 1 claim (now included in the north-western portion of the Ralph mineral claim) with a maximum thickness of 700 feet and a minimum thickness observed of some 300 feet. It continues southeasterly along strike through the Ralph, Corner and at least a portion of the Sandy mineral
claim and thus for a strike length of at least 10,500 feet. The remaining quartzite in this 1600 foot to 2000 foot thick zone is hard competent quartzite and is separated from another zone approximately 2800 feet thick of the same lithology by a 2000 foot thick band of limestone. The hard quartzite can be described as frosty white sedimentary quartzite with a clastic texture containing fine, well-rounded polished grains 1/8 - 1/4 m in diameter. Very competent bonding allows
breaking to occur through the quartz grains. Minor iron staining occurs along some fracture planes and is interstitial to the quartz grains in some small sections. Chemical analysis has shown the quartzite to contain greater than 99.5% SiOZ in some of the areas sampled.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Moberly silica sand deposit was drilled by four cored holes in 1982 with logging was largely done on a qualitative basis and indicates the homogeneity of the deposit at depth, although this would be essentially down-dip of the sandstone beds. Extensive exposure and mining in three dimensions by open cut mining.


Crushing and Grinding


Processing

  • Wash plant

Summary:

Frac sand is manufactured from naturally occurring pure quartz sand via a straightforward crushing, grinding and washing process and is used as a proppant for the oil and gas sectors; chiefly the shale gas industry.
