Brodie Pit No. 0597
2017 Technical Information Report
Location:
The pit is located approximately 44 km southwest of Merritt via and adjacent to the Coquihalla Highway
at Exit 250.
Legal Description:
Unsurveyed Crown Land together with that portion of DL 599, Yale District. The pit is covered by a
Section 16 Map Reserve in the name of the Ministry of Transportation & Infrastructure. The geographic
coordinates for the pit are UTM Zone 10, 5520200 Northing, 648500 Easting.

Gradation:
The average and range of laboratory samples and oversize rock field estimates from the 2017
testing program at Brodie Pit are as follows:
Laboratory Samples
Classification:
Average (%) Range (%)
Gravel (4.75-75mm) 51.0 22.5-78.6
Sand (0.075-4.75mm) 46.8 20.4-72.9
Fines (<0.075mm) 2.2 0.8-7.5
Oversize Field Estimates
Classification:
Average (%) Range (%)
Boulders (>375mm) <1 0-1
Cobbles (150-375mm) 3 0-12
Cobbles (75-150mm) 6 1-18
The maximum rock size observed was 400 mm. The rock found in TP17-05 and TP17-06 was
not included in the averages/ranged noted above. These test holes contain small to medium sized
cobbles intermixed with some sands and gravels (see photo of TP17-05 on Page 9). These
locations have been excluded from the recommended suitability area on the Pit Development
Plan, however, the material is still accessible and available if needed.

Granular Volume:
Estimated volume: 45,000 m3
Pit Development and Recommendations:
The mining area has been previously developed by the Ministry of Transportation and
Infrastructure (MoTI). Any additional development will be the responsibility of the
contractor and shall be completed as per the pit development plan or as directed by the
Ministry Representative.
Due to a high percentage of oversize rock contained within the deposit the use of a primary
crusher is required during aggregate production.
The crusher is recommended to be located as identified on the Pit Development Plan to the
north of TP17-01, with mining proceeding in a northeast and southeast direction as indicated.
Processed aggregate may be stockpiled north of the suitability area where space permits.
Some minor stripping may be required prior to mining and aggregate stockpiling. If
additional development is required it shall conform to the requirements of the pit
development plan or be completed as directed by the Ministry Representative.
At the completion of mining, active pit faces shall be sloped to a minimum of 1 ½:1 with
granular material.
All reject materials resulting from aggregate production are to be placed in separate
stockpiles free from deleterious material and in an easily accessible location. No
stockpiling against the pit face is permitted without the permission from the Aggregate
Resource Manager.
