However future work on the Ontario property will be reviewed by the joint venture following completion of the sale of GTA's mineral property assets, which remains pending.
GTA currently has a 54% interest in Northshore and is the project operator.
GTA shareholders last month approved the sale of its mining assets to CBLT Inc (TSXV: CBLT) and to voluntarily delist from the TSX Venture Exchange, along with other conditions to meet a C$425,000 loan agreement struck with CBLT in October.
At the time, GTA president and CEO Peter Clausi said the decision was not made lightly and he believed GTA's shareholders would be "better served in a growth industry other than junior exploration" while still having exposure to the assets through the to-be-dividended shares of CBLT.
Clausi is also CEO of CBLT, saying in October "the brutal junior mining market has created opportunities for us".
The two companies also share a CFO and director in Brian Crawford.
