Vein-type graphite deposits hosted in igneous rocks are globally rare; however, these deposits have the potential to produce high-purity graphite required to compete with the $8 billion per year synthetic graphite market. Ultra high-purity graphite (>99.95% C) is required to support Canada's emerging green technology sector, as this type of graphite is required for the manufacturing of Li-ion batteries, fuel cells, graphene-based applications, pebble-bed nuclear reactors. Canada is on the verge of potentially developing the world's first igneous-hosted vein graphite deposit, the Albany deposit, near Hearst, ON. Zenyatta Ventures Ltd, who is the industrial sponsor of the proposed research, discovered Albany in 2010. As mining and processing costs for vein graphite would come at much lower production and environmental costs than synthetic graphite (produced by expensive and energy demanding refinement of petroleum coke), the principal benefit to Canada is the establishment of its own supply of ultra-high purity graphite for its emerging green technology sector. Although the potential economic benefits are significant, the geological understanding of igneous-hosted is limited owing to very few known global discoveries and the resulting paucity of data on igneous-hosted vein deposits. Consequently, a research partnership between Zenyatta Ventures and Lakehead University has been established to study the origin of the Albany deposit. This research will involve the integration of field and laboratory techniques, including core logging, microscopic studies, whole-rock geochemistry, spectroscopic investigations, radiogenic isotope geochemistry, geochronology and stable isotope geochemistry. In addition to the potential long-term economic benefits, Canada will benefit in the short-term through student training and research, which will lead to the development of more robust mineral deposit models, which can be applied by exploration industries in Canada and by Canadian companies working abroad to aid in future discoveries.

在火成岩岩石中托管的静脉型石墨沉积物在全球范围内很少。但是，这些存款有可能生产高纯石墨，以与每年80亿美元的合成石墨市场竞争。需要超高纯度石墨（> 99.95％C）来支持加拿大新兴的绿色技术领域，因为这种类型的石墨是制造锂离子电池，燃料电池，基于石墨烯的应用，卵石床核反应堆所必需的。加拿大即将发展世界上首个火成岩托管石墨矿床，即赫斯特附近的奥尔巴尼矿床。拟议研究的工业赞助商Zenyatta Ventures Ltd在2010年发现了Albany。由于静脉石墨的采矿和加工成本将比合成石墨的生产和环境成本低得多（由昂贵的和能源需求的石油coke的改进而产生的，因此对加拿大的主要供应了其自身的绿色供应商的供应供应的供应工具，这是其自身供应的供应供应。尽管潜在的经济利益是显着的，但由于很少有已知的全球发现以及对火成岩托管静脉沉积的数据的匮乏，对火成岩托管的地质理解受到限制。因此，已经建立了Zenyatta Ventures与Lakehead University之间的研究伙伴关系，以研究奥尔巴尼矿床的起源。这项研究将涉及现场和实验室技术的整合，包括核心记录，微观研究，全岩地球化学，光谱研究，放射原性地球化学，地球人工学和稳定的同位素地球化学。除了潜在的长期经济利益外，加拿大还将通过学生培训和研究在短期内受益，这将导致开发更健壮的矿产存款模型，加拿大的勘探行业和加拿大公司可以使用，这可以应用于加拿大的加拿大公司，以帮助未来的发现。
