Assume you are an investment planner in a major mining firm and your mine exploration

team notifies you that they found gold in a potential mine. You know that mining is a long$-$

term investment that has a long payback period that can be up to $20$ years. Therefore,

you must carefully calculate the potential revenue and costs and report your findings to the

company executives for them to decide whether it is feasible to invest in this potential field.

To create the comprehensive financial plan, you consider the lifecycle of a Gold Mine

which has four major stages:

$1.$ Gold Mine Exploration and Discovery:

Gold mine exploration consists of searching for gold ore in a location that requires

expertise in many disciplines $$ e$.$g$.,$ geography, geology, chemistry, and engineering. If

initial indicators are found, we want to explore the area to make sure we have a feasible

amount of valuable minerals to invest in there.

$1$

$2.$ Gold Mine Development: Reaching this stage means that you are lucky; exploration

and discovery investments were not a total loss. This stage starts with the investment of

the feasibility study, performing it$,$ raising the funds, and getting mining permissions.

Since your company has multiple operations, you will need to output the name of the

mine. However, they haven$$t decided on a name yet. It will be given as input to your

program when it is run. Write a line of input that takes the name of the mine and

stores it into a variable.

You also need to account for all investments required to reach the orebody. The table

below lists the initial costs of mine development. Write a statement to calculate the

sum total of all development costs and store it in a variable. Print this variable as

output.

Items Cost $($in Million USD$)$

Land, Buildings $145\mathrm{.}23$

Main Equipment $36\mathrm{.}2$

Openings development $209\mathrm{.}5$

Infrastructure $80\mathrm{.}7$

Tailings Dam $48\mathrm{.}1$

Miscellaneous $28\mathrm{.}2$

$3.$ Gold Mine Exploitation: After reaching the orebody, the ore is extracted and

processed into dor $$e $(60\%-90\%$ gold containing metallic alloys$)$ and then this dor $$e is

transported into refineries to obtain pure gold.

We have to calculate the yearly potential operating revenue and cost to see whether

our mine is profitable or not. Our total cost is the sum of excavation, processing,

employee salaries, and other items, as listed in the table below. Your program should

calculate the sum of all yearly operating costs, store it in a variable, and print it

as output.

Items Units Unit Price $($USD$)$ Count $($per year$)$

Excavation Metric Ton $($T$)$ $$9$ per T $1\mathrm{.}0$ Million T

Processing Metric Ton $($T$)$ $$10$ per T $1\mathrm{.}0$ Million T

Employees People $$100,000$ per Employee $150$

Utilities & Other $-$ $$100,000,0001$ per year

Next, we want to calculate our gold price and yearly revenue. This requires several

steps:

$($a$)1$ Metric Ton of ore contains $11$ grams of gold, and we expect to extract $1$ million

T of ore yearly. After extraction, we get a dor $$e that is sent to a refinery. The

$2$

refinery refines the dor $$e into $100\%$ pure gold. However, as a processing fee, the

refinery takes $5\%$ of the product and hands over the rest as gold bars. Calculate

the resulting pure gold bars you get in a year in grams, store it in a

variable, and print it as output.

$($b$)$ The gram price of pure gold is constantly changing. Therefore, we need to update

this information without having to change the code. Write an input line to ask

the user to input the expected gold price.

$($c$)$ Combining the steps above, write code that calculates the yearly revenue and

store this number in a variable.

NOTE:

$1$ Metric Ton $=1000$ Kilograms

$1$ Kilogram $=1000$ grams

$4.$ Gold Mine Closure and Reclamation:

After the mine is deemed unprofitable, the mine is closed and all its related facilities

are dismantled. The mining company is responsible for the re$-$vegetation, and rehabil$-$

itation of the land. We assume this will cost $$150$ Million; store this reclamation

cost in a variable.

Input

The program will take two lines of input:

$1.$ The name of the mine

$2.$ Expected price per gram of gold $($an integer$)$

Output

Company executives will expect the program to print out a report of our
