Is the mining sector successful at this point in time?

The mining sector has typically gone through "boom and bust" cycles that depend on commodity prices. For example, gold mines flourish when the price is high (say around $1000/oz), but when the price drops significantly (to say half this amount) many gold operations will shut down for awhile or permanently. Commodity prices are dependant on the demand for that particular mined commodity.

As a result of growing concerns about climate change, many governments in North America are phasing out the use of coal for power generation, making the coal mining industry unprofitable. Similarly, uranium mining appears to be in trouble as many governments are abandoning the construction of nuclear reactors due to safety concerns.

Since China's economy is not expanding as quickly as it once did, base metal mining (iron, copper, zinc, and lead) has been relatively strong over the last ten to fifteen years. As a result, the price and demand for these metals have decreased or become more erratic.

While there are plenty of jobs in mining for geologists, engineers, and businesspeople, the job security aspect of the industry can be a little dicey.

The success of the mining sector can vary depending on various factors such as commodity prices, demand, regulatory environment, technological advancements, and geopolitical stability. It's essential to analyze specific data and trends within the sector to determine its current success.
