Abstract
The property is underlain by the St Peter Sandstone, of Ordovician age, and is homogeneous pure quartz sand. The St Peter sandstone (also known as the Ottawa sand in commercial operations) is considered to be a major source of frac sand within the United States, especially in Wisconsin. The Arkansas Geological Survey reports that in the nearby Mt. Pleasant area the sand ranges from 135 - 150 feet in thickness. On the Bray property, drilling by Rainmaker has demonstrated thicknesses in excess of 120 feet. Bluebird Sand LLC produces frac sand from the same formation.
The sand deposit lies at surface and consists entirely of beach sand from the shores of glacial Lake Agassiz. This lake covered much of the central Prairies until approximately 10,000 years before present. Wave action on the beaches has resulted in clean, well-rounded sand grains, which may be suitable for hydraulic fracturing. The sand is derived from a marine quartzose sandstone horizon in the Cretaceous Manville formation.
Rainmaker Resource Corp., a well-rounded frac sand company, has acquired frac sand assets in Canada and the United States: Jayjay Lake project in north-central Saskatchewan and The Bray Property in Arkansas. Both projects have excellent access to key infrastructure and are close to existing frac sand producers.
