Mine Life15 years (as of Jan 1, 2020)
On February 2, 2021, Agnico Eagle completed the acquisition of TMAC for consideration of approximately $226.0 million. In September and October of 2021, there were a significant number of COVID-19 cases identified at the Hope Bay project. As a precautionary measure, the Company decided to suspend mining and milling operations. The Company started to ramp-up exploration and underground activities in mid-November 2021. However, with increasing cases of COVID-19 in December 2021, the Company again reduced all activities at site to essential services only. The Company determined in February 2022 that production activities would be suspended for the remainder of 2022 and 2023 and the Company’s primary focus during this time would be accelerating exploration and the evaluation of larger production scenarios.

On February 2, 2021, the Company acquired all of the issued and outstanding common shares of TMAC pursuant to a court-approved plan of arrangement under the Business Corporations Act (Ontario). At the time, TMAC was a Canadian based gold mining company that was listed on the Toronto Stock Exchange (“TSX”) and held a 100% interest in the Hope Bay project in Nunavut.

Deposit Type

  • Breccia pipe / Stockwork
  • Mesothermal


Summary:

The Hope Bay Property is located within the Hope Bay volcanic belt which is part of a massive structural-geological complex called the Slave Structural Province.

The Hope Bay deposits (Doris, Madrid, and Boston), as well as a large number of other prospects, are considered to be typical of orogenic-type mesothermal lode gold deposits, greenstone-hosted quartz carbonate vein deposits.

• The Doris gold deposit is a typical Archean lode deposit which occurs within an over 3 km long, steeply dipping quartz vein system, in folded and metamorphosed pillow basaltic rocks.
• The Madrid deposit area lies within a north-south striking package of mafic volcanic rocks, comprising a sequence of Fe-Ti tholeiitics, Mg tholeiitics, komatiitic basaltic, synvolcanic to late gabbroic, and ultramafic rocks.
• The geology in the area of the Boston deposit is a bimodal assemblage of mafic and felsic volcanic rocks in contact with sedimentary rocks, all of which are complexly folded about a large-scale synformal-anticline. The core of the anticline is occupied by mafic volcanic rocks that host the Boston deposit and these are in turn overlain by sedimentary rocks.

THE DORIS AREA
The Doris Deposit is located at the north end of the north-south trending Hope Bay greenstone belt of Archean age near Cambridge Bay in Nunavut. Gold mineralization is contained within predominantly sub vertical quartz veins hosted within mafic volcanic rocks.

Mining Methods

  • Truck & Shovel / Loader
  • Longhole stoping
  • Transverse stoping
  • Longitudinal stoping
  • Cemented backfill


Summary:

During 2018 and 2019 a small open pit was mined near Doris Lake where the hinge outcropped at surface.

A small open pit is being mined on the Naartok East Limb.

Mining at the Hope Bay Project incorporates longhole mining methods in order to address the deposit geometry and anticipated ground conditions. Mining will take place under permafrost conditions where the mineralization is located away from any water bodies and under nonpermafrost conditions in what is known as the talik in the vicinity and under the lakes in the area.

Doris North will be under permafrost while the Connector and Central zones at Doris will be beneath the lake. A portion of the Madrid North deposit (part of Naartok) as well as the Madrid South deposits (Patch and Wolverine) are situated beneath the lakes and therefore will not be under permafrost conditions.

The deposits will be accessed, and services will be provided by a decline from surface with an average grade of 13%. The ramp will also be used for ore and waste haulage from the underground operations.

The Doris deposit is in production, with an existing ramp decline reaching active mining areas. Mining will continue as per current methods until depletion. Transverse and longitudinal longhole mining is planned for Doris. Madrid North (Naartok and Suluk) and Boston will be mined using longhole stoping methods with sub-levels placed at 20-m vertical intervals (16-m drilling heights). Bot ........
