Mine Life2020
Holt Mine Complex consists of three mines: The Holt Mine and Mill and the Holloway Mine, and the Taylor Mine located approximately 68 km by road west of the Holt Mill.

Operations were suspended at the Holt Complex effective April 2, 2020 as part of the Company’s COVID-19 response and while the Company conducted a strategic review of these assets. In July 2020, the Company announced that the suspension of operations at Holt Complex would be extended until further notice. As a result, there was no production, sales, operating costs or capital expenditures from Holt Complex in Q3 2021 or YTD 2021. Care and maintenance costs in YTD 2021 related to Holt Complex totalled $3.7 million ($0.8 million in Q3 2021). In addition, the Company recorded an asset impairment of $6.5 million related to the disposal of equipment at the Holt Complex in Q1 2021.

Summary:

Regional Geology
The Taylor Mine Complex is located along the Porcupine-Destor Fault Zone (PDF), a major structural feature associated with globally significant gold deposits lying within the Abitibi Greenstone Belt of northeastern Ontario and north-western Quebec.

Local and Property Geology
The Taylor Mine Complex is almost entirely covered by glacial overburden, ranging from 3 m to 60 m in thickness (generally 30 m to 40 m thick). Thus, interpretations of the property geology have been made principally from diamond drill hole information as well as the underground excavations in the shaft and ramp areas developed in the Shaft Deposit.

The Taylor Mine Complex is located along the PDF in its central portion, approximately 60 km east of the main gold producers in the vicinity of Timmins. The PDF in the area of the Taylor Mine Complex strikes roughly east-west, and dips to the south between 40° and 60°, with the majority of the property lying to the south of the projected trace of the PDF. The PDF is a complex structural zone and it is more accurately described as a zone of tens of metres width, along which are contained many individual zones of movement. In the Taylor property area, the footwall of the PDF is considered to be a thick series of relatively undeformed and unaltered metasedimentary rocks intersected to the footwall.

Mining Methods

  • Drift & Fill
  • Overhand Cut & Fill
  • Longhole stoping
  • Cemented backfill


Summary:

The Taylor Mine consists of a few zones: the Shoot Deposit (located on the west side of the property), the West Porphyry Deposit (WPZ), the East Porphyry Deposit and the Shaft Deposit (located on the east side of the property).

The WPZ extend vertically about 600 m and is mostly open at depth. The WPZ is accessed via a ramp and mined by overhand cut and fill method (for shallow dip ore zones) or longhole stoping (where the ore zones dip at an angle greater than 45°). Ore and waste are trucked to surface where the ore is loaded into surface trucks for haulage to the Holt mill and the waste is stockpiled on designated surface areas.

Overhand Cut and Fill (OC&F) and Drift and Fill (D&F) were selected as the most suitable mining methods:
- Where the ore is dipping at less than 45° and the ore horizontal width is narrower than 10 m, OC&F is the method of choice;
- Where the ore is dipping at less than 45° and the ore horizontal width exceeds 10 m, D&F will be the method of choice.

Where the ore is dipping at more than 45°, longhole mining will be the method of choice, requiring minimum mining width of 3 m. Waste rock generated by development activities is the source of backfill (whether cemented or not).

Upon examination of the mining shapes, the geologist applied a dilution factor varying from approximately 10% to 50% and a dilution grade ranging from approximately 0.5 g/t to 1.0 g/t. Mining extraction varied from approximatel ........
