Sudbury 2.0 Project, Ontario, Canada
Inventus' Sudbury 2.0 Project is targeting the source of the Temagami Magnetic Anomaly, a large magnetic anomaly that may be related to the Sudbury Igneous Complex, a world class magmatic Ni-Cu-PGE mining camp. The Sudbury mining camp has produced approximately 1.7 billion tonnes of ore with historic production and current known reserves valued around 1 trillion dollars at current commodity prices.
The Temagami Anomaly was of great interest to Falconbridge (now Glencore) during the 1990's. Falconbridge geologists believed that the Temagami Magnetic Anomaly could be related to a magmatic intrusion. It was thought that the anomaly was an excellent exploration target due to its size, magnetic intensity and location relative to the Sudbury Mining Camp. Falconbridge staked the entire anomaly and carried out exploration into the early 2000's.
In 2014, a 2,200 metre hole was drilled by Canadian Continental into the peak of the Temagami Magnetic Anomaly. Core examination conducted by Inventus suggested a strong resemblance to marginal units of the Sudbury Igneous Complex, including sublayer norite and offset quartz diorite dykes.
Subsequent academic work conducted by the University of Wuerzburg in 2017 has determined the magnetic mafic intrusive in hole AT-14-01 to have similar rare earth element geochemistry to the unique offset dykes occurring around Sudbury. The report can be viewed below.
Inventus' Sudbury 2.0 Project is located east-northeast of Sudbury, Ontario. The property is easily accessible by road. See map below for general location.
The Sudbury 2.0 project consists of 188 square km's of mineral claims covering the Temagami Anomaly. Inventus owns a 100% interest in the property. Additionally, Inventus owns 18% of the issued and outstanding shares of Canadian Continental Exploration, which holds claims to the east of the Sudbury 2.0 Project area.
The general surface geology on the property consists mainly of rocks of the upper Huronian Supergroup, a 2.45 to 2.2 Ga sedimentary basin. Other rocks in less abundance in the area include the Nipissing Diabase, a 2.2 Ga mafic intrusive and Olivine Diabase Dykes relating to a 1.28 Ga mafic dyke swarm. Present also on the property are small mafic dykes of unknown origin and areas of extensive hydrothermally brecciated Huronian rocks that could be Sudbury-type breccia, related to the Sudbury Igneous Complex.
Ore Deposit Model
Rocks of interest on the property are the mafic dykes, which could be related to the Sudbury Igneous Complex, and hydrothermal breccia, which is known to contain Au-Cu mineralization in the Wolf Lake Area.
Inventus believes three styles of mineralization can exist on the Sudbury 2.0 Project:
- Sudbury-type magmatic Ni-Cu-PGE-Co-Au mineralization
- Wolf Lake-type hydrothermal Au-Cu breccia
- Strata-bound Pardo-type paleoplacer Au mineralization in the lower Huronian Sediments
The first two styles of mineralization could be the result of an underlying magmatic intrusion related to the Sudbury Igneous Complex.
Pre 1950's - Individual Prospectors held claims in a variety of areas on Inventus' property with little to no reports on activities.
1970 to 2011 - Flag Resources held mineral claims over Wolf Lake and various other areas. Flag was focused on breccia hosted Au-Cu mineralization and did not understand the potential of a deep seated magnetic intrusion until the mid 1990's when their company
1991 to 2000 - Falconbridge staked the entire anomaly in the 1990's conducted some geophysical survey's and drilled one hole. There one drill hole deviated from the target and was abandoned.
1999 - Wallbridge drilled one hole as part of an agreement with Falconbridge. The hole was called at 1200 metres and the source of the magnetic anomaly was not intersected.
In the upcoming 2018 field season, Inventus plans to conduct prospecting and geological mapping in areas of interest. The primary goal is to locate occurrences of mafic dykes and structures containing alteration and Sudbury-type breccia. Inventus plans to sample these areas carefully and conduct geochemical and petrographic analysis of the rocks. Any areas with encouraging results will be extensively explored by mapping and prospecting in greater detail, as well as geophysical surveys and diamond drilling if warranted.
