Statement of Contribution: Your submission must include a separate Statement of Contribution outlining the individual contribution from each member of the group. All members must agree to and sign this statement of contribution. In addition, we may have a group members interview for allocation of individual marks. In addition, all internally enrolled students must must actively participate and engage in Whittle software Lab sessions where they will complete the Whitle software tasks individually.
Learning objectives/outcomes:
1. Outline mine planning processes, opportunities and constraints associated with a mining operation.
2. Develop mine plans through manual procedures, mathematical models, and mining software.
3. Analyse and communicate mine plans for real-life scenarios.
Introduction:
This group project covers the following two aspects of the unit/course learning outomes:
1. Part A: Ultimate pit limit design, production scheduling, and after-tax discounted cash flow analysis of a hypothetical orebody using manual procedures.
2. Part B: Ultimate pit limit design and production scheduling of large-scale realistic orebodies using GEOVIA Whittle® software. Note that this document provides information about Part B.
Part B - Whittle® software - realistic/existing copper deposit (15%)
Blended learning approach: Accomplishment of the project requires a mandatory pre-lab learning of the Whittle software through pre-recorded videos available in Week 4 of the Unit Materials.
Based on the pre-lab learning, all internally enrolled students are required to actively participate and engage in their respective lab sessions for the Whittle software. Within the allocated three-hour timeframe, students must complete the designated tasks given below. Following individual completion, students will collaborate within their groups (including externally enrolled group members), sharing their work and engaging in a follow-up discussion to select the appropriate/best work as a submission.
Given the significance of achieving the learning outcomes associated with the Whittle software component, any internally enrolled member of the group who chooses not to participate in their assigned lab session should expect a deduction of 10% of the total for Part B. It's important to note that no assessment extensions for participation in the allocated lab session will be granted under any circumstances.
Problem statement
Given a large porphyry copper orebody model from an existing project and other relevant input parameters, develop strategic mine plans in terms of optimal ultimate pit limit, phase design, and production schedule using GEOVIA Whittle® software.

Technical/operational and economic inputs:
Element units = Copper (Cu) in % Pit slope angle = 44°
Copper price = $5,700.00 per tonne of Cu,
Copper treatment, refining and selling charges = $1100.00 per tonne of Cu, Ore mining cost = $3.50 per tonne of ore,
Waste mining cost = $4.20 per tonne of waste (hard-digging), Waste rehabilitation cost = $2.30 per tonne of waste,
MCAF = 1.0,
Mining recovery = 96%,
Processing cost = $12.50 per tonne of ore,
Processing recovery = 92%, Discount rate = 10%.
Copper demand = 125,000 tonnes per year
Irrespective of the mining and processing capacities, the mining and processing overheads are expected at $2,400,000 per year.
Scenario 1 - Base case @ oreselection method = cut-off
I. [Marks = 25] Determine the appropriate scale of mining and processing capacities using Whittle® software.
II. [Marks = 5] Given the mining and processing capacities in Part (I), calculate the initial capital cost (ICC), assuming that ICC = $400,000T0.6 (Hustrulid et al., 2013) is applicable in the current Australian environment. Note : T is the processing rate in tonnes of ore per day (assume opertaion runs 365 days per year).
III. [Marks = 25] Develop an ultimate pit limit, phase (pushback) design, production schedule, and sensitivity analysis (change commodity price (±10%) and processing cost (±10%)).
Scenario 2 - MCAF and capacity expansion MCAF changes as follows:
First 6 benches incur reference mining cost, next 9 benches, each bench incurs additional $0.05 per tonne of material, last 18 benches, each bench incurs additional $0.06 per tonne of material.
Capacity expansion
Owing to the shortage of available capital, the operation explores the option to provide relatively lower mining and processing capacities initially (i.e., year 1 to 4 @ mining capacity = 6,000,000 tonnes, processing capacity = 4,000,000 tonnes, and refining capacity = 30,000 tonnes) with the possibility to expand later to full capacity (Scenario I-I) from year 4 onwards.
IV. [Marks = 40] Develop an ultimate pit limit, phase (pushback) design, production schedule, and sensitivity analysis (change commodity price (±12%) and processing cost (±12%)) under MCAF and capacity expansion options.
V. [Marks = 5] Present results in Scenarios 1 and 2 in a table as your executive summary.
