The following information is taken from a Nova Scotia Government website listing mineral occurrences in the Province: Carbonotec Industries et al. (1986): Kelrock Ltd. optioned the ground to Carbonotec Industries who conducted an exploration program, bulk milling tests and market studies. The prospect was described in their report as follows: "Reserve: there has not been enough work done on the property to estimate ore reserves especially in a case such as this where the economic variables more or less dictate what can be considered to be mineable. However, the consistency in carbon content and the type of deposit are indicators that extrapolation of surface information will provide a reasonably accurate picture of the extent of the ore. Morever, the deposit has unique mining and market potential that allows a grade cut off far below normal for this type of ore body. Within that framework, the probable ore reserves exceed one million tons in the explored zone. If the operation can be optimized there may be recoverable reserves in excess of 10,000,000 tons. Additional work is required to prove up the reserves. Initial sampling confirmed historical data which showed the ore having carbon content of 40-60% as amorphous (cryptocrystalline) graphite. Subsequent work showed that the carbon content was lower than anticipated, being 35-50% C: that the sulphur content was much higher at 3-55%, as opposed to 0.2 - 0.3% S shown in weathered samples: that the degree of graphitization was less than expected and the possibility of flake graphite was discounted entirely. However, very large tonnage appears likely, though, the structure is somewhat more complex than originally envisioned." The Carbontec report goes on to describe "spherical agglomeration tests were very successful in improving the concentrate grades. Carbon levels of +80% were quickly attained with very high recovery (90%).

Fine grained, amorphous graphite is developed to varying degrees in black, schist or phyllites. Black calcic marbles and white dolomitic-marbles are interbedded with the schists, but these two units do not appear to host much obvious graphite mineralization. The graphitic schist appears to represent a dynamically metamorphosed (sheared) black, carbonaceous slate. Ovoid shaped pyrite nodules occur in high concentrations in localized areas within the graphitic schist unit.

Hill (1989): The deposit was studied as part of Hill's regional studies of mineral occurrences hosted by Precambrian carbonate rocks on Cape Breton Island. Hill described the occurrence as follows: " The Glendale graphite showing is located on the west side of the Glen Brook Valley, adjacent to the Glendale calcite marble occurrence. The showing consists of at least two highly deformed, carbonaceous to graphitic and pyritic schist zones, 100m wide, in black, cryptocrystalline limestone and siliceous dolostone. It is unclear whether the graphite schists represent bedding parallel layers in the carbonate sequence or discordant shear zones. The carbonaceous layers are likely sedimentary in origin but have undergone some degree of remobilization and perhaps concentration during regional metamorphism. Up to 31% non-carbonate carbon is found in samples from the most carbonaceous zone. Pyrite nodules 5 cm in diameter and containing anomalous gold (up to 28ppb), have developed within the graphitic schist. "

Miscellaneous reports (1931-32): Two short shafts, 2 adits and several trenches and test pits were dug on the graphite showing between 1931 and 1932. An extensive graphite deposit with a strike length of over 3000 feet was outlined by this work. The graphite content was reported to increase with increased depth below the surface. Samples of the graphite were sent to the Hydro-Electric Power Commision in Ontario to be tested for paint filler. This testing returned very positive results.

The deposit was described by Messervey as follows: I traversed the first brook above tunnel "A" and at a distance of three hundred feet above the tunnel I found another graphitic deposit about fifty feet in width and about six hundred feet west of the tunnel there was evidence of graphitic material over a zone of one hundred feet. The deposits are amorphous graphite and occur in beds of varying thickness standing at angles of about thirty to fourty degrees in a country rock of impure crystalline limestone. The limestone is metamorphosed and the graphite beds were undoubtedly formed by the metamorphism of coal beds. West of this limestone occur Precambrian syenitic rocks so that the limestone may be a shallow water deposits on these older rocks. These limestones were classed by the Geological Survey as upper Precambrian."
