On November 7, 2018, Talon and Kennecott entered into an agreement (the 2018 Tamarack Earn-in Agreement) pursuant to which Talon has the right, subject to certain funding and reporting obligations, to increase its interest in the Tamarack Project to a maximum 60% interest and become the manager/operator of the Tamarack Project. The 2018 Tamarack Earn-in Agreement is subject to approval by the Talon shareholders of a financing required to be completed by Talon in connection with the Tamarack Project, such shareholder approval to be sought at a meeting to be held on or before January 31, 2019.
Summary:
The Tamarack Intrusive Complex (TIC) is an ultramafic to mafic intrusive complex that hosts Ni-Cu sulphide mineralization with associated Cobalt (Co), Pt, Pd (PGEs) and Gold (Au).
The geometry of the TIC, as outlined by a well-defined aeromagnetic anomaly, consists of a curved, elongated intrusion striking north-south (NS) to southeast (SE) over 18 km. The configuration has been likened to a tadpole shape with its elongated, northern tail up to 1 km wide and large, 4 km wide, ovoid shaped body in the south (S). The northern portion of the TIC (the Tamarack North Project), which hosts the currently defined resource and identified exploration targets, is over 7 km long and is the focus of this PEA.
The Ni-Cu sulphide mineralization with associated PGEs and Au form as the result of segregation and concentration of liquid sulphide from mafic or ultramafic magma and the partitioning of chalcophile elements into the sulphide from the silica melt.
Mining Methods
- Drift & Fill
- Longhole open stoping
- Paste backfill
Summary:
The mining method proposed for the Upper and Lower SMSU (semi-massive sulphide unit) is transverse long hole open stoping with cemented paste backfill.
The mining method proposed for the MSU (massive sulphide unit) zone is overhand, transverse drift-and-fill with a cemented paste backfill.
Paste backfill will be used for the majority of the backfilling requirements for the Tamarack North Project for ground stability, increased ore recovery, and to minimize the quantity of tailings stored on surface. A strong backfill that includes the addition of cement is required for the primary MSU and SMSU stopes. The secondary long hole open stopes and driftand-fill stopes can be filled with a backfill requiring less cement.
Flow Sheet:
Summary:
The metallurgical process consists of bulk rougher and scavenger flotation followed by separate cleaning of the rougher and scavenger concentrates. The upgraded rougher concentrate is subjected to Cu/Ni separation. The process generates separate Cu and Ni concentrates. Further, the bulk scavenger tailings are treated in a desulphurization stage to produce a low-mass HS stream and high-mass, potentially NAG tailings.
