Located three kilometres from the Chisel North mine, the Lalor project is on a fast track to become our next major underground mine. The project is believed to hold the second-largest metal deposit in the Flin Flon Greenstone Belt and the largest pre-development deposit discovered in the Flin Flon-Snow Lake region.

Project Status

At Hudbay’s 100% owned Lalor project in Manitoba, of the total mine construction budget of $441 million, Hudbay has invested approximately $404 million and has entered into an additional $32 million in commitments to June 30, 2014. Hudbay has completed the underground mine project development. The company has also completed the new 6,000 tonne per day capacity (ore and waste) production shaft and mechanically commissioned it for hoisting as well as personnel transport.


Construction is complete on the 910 and 955 metre levels on the mine dewatering systems, rock breakers and the loadout systems. There is minor electrical work remaining that is expected to be completed in August 2014. Commissioning of the rockbreakers and loadout systems is complete and Hudbay will commission the main de-watering system after the remaining electrical work has been completed. The remaining committed funding is largely for the office/changehouse and surface exhaust fan installation. Hudbay expects the completion of the remaining surface construction to be completed in late 2014. Hudbay has substantially completed the refurbishment of the Snow Lake concentrator which will be commissioned to treat 2,700 tonnes per day, doubling its previous capacity.


An underground exploration drift at Lalor will be started in the third quarter of 2014 at an estimated cost of $3.1 million. The exploration drilling is intended to assist in the upgrading of inferred resources to a higher resource category and allow for an expanded program in 2015 to further test the down dip extension of the copper/gold zone.

1955 – Exploration in the Chisel Basin has been active since 1955. The Basin has hosted five producing mines: Chisel Lake, Chisel Open Pit, Chisel North, Photo and Ghost-Lost.

2007 – Lalor deposit is discovered.

2009 – Gold zone and copper-gold zone identified. In December, construction begins on the three-kilometre underground ramp from the Chisel North mine to Lalor deposit.

2010 – Hudbay's board of directors made a full commitment to the development of Lalor by authorizing the expenditures necessary to put the project into full production.

2011 – Decision made to construct new concentrator.

2012 - Initial ore production commenced from ventilation shaft

2014 - Lalor mine construction complete on time and on budget
