Berkwood Resources Ltd (CVE:BKR) announced more positive news Tuesday as it revealed that testwork on its graphite concentrate from Lac Gueret South in Quebec had shown it could potentially be sold into a wide-range of markets.
The material can be expanded and the concentrate can easily be purified to 99.95%, the Vancouver based firm told investors in a statement.

Testing was carried out by ProGraphite GmbH in Germany, which is recognized for determining graphite qualities specific to various end uses, it added.
"This report is one of the final pieces of the puzzle that was crucial for Berkwood," said CEO Tom Yingling.
"The company knew we have high-grade graphite and large flakes. From the recently announced NI 43-101 resource estimation report, we knew that Berkwood has a substantial amount of it and it is right on surface. One of the last pieces of the puzzle we needed to know was if the graphite is able to be expanded, and, can it be done so very easily using standard methods," he added.
Yingling also confirmed that the graphite concentrate can be easily purified to 99.95%.
"For Berkwood, this opens up the opportunity to sell our graphite flakes into a wide range of standard and value-added graphite markets," he said.
Expandable grahite is achieved by inserting molecules between the carbon layers. During this process, which is named intercalation, the expanded material takes on new properties - such as an increase in the volume of the graphite of up to 375 times and around a 10-fold increase in surface area.
The worldwide market for expandable graphite is among the fastest growing along with Li-Ion batteries, noted Berkwood, and has seen significant price increases in the last couple of years.
Uses for expandable graphite include flow batteries and fuel cells, coatings, aerospace, energy storage, wind energy and semiconductors.
Earlier this month, Berkwood said it was on the hunt for a joint venture partner and/or an off-take agreement for the Lac Gueret project
A maiden resource estimate has shown 549,200 tonnes of contained graphite, with 299,200 tonnes in the higher confidence indicated category and 250,000 tonnes in inferred.
The resource has an estimated market value of US$1,500 per tonne as used in the NI 43 101 estimate announced last month.
