Final answer:
Major copper and gold reserves were discovered in Reko Diq, Balochistan; with significant potential economic impact, the development has faced legal and political challenges.
Step-by-step explanation:
The major reserves of copper and gold were found in the Reko Diq area of the Chagai district in Balochistan, Pakistan. This region is known for its massive deposits of minerals. Reko Diq itself is famous as one of the most lucrative undeveloped copper and gold mines in the world.
The discovery in Reko Diq represents a significant find due to the value and scale of the copper and gold reserves. It was estimated that the potential economic impact of exploiting these reserves could be profound, potentially transforming the region's economy. However, the development of Reko Diq's mining potential has been subject to legal and political challenges, including issues of provincial autonomy, environmental concerns, and economic terms for the extraction of resources.
Lying in the mineral-rich Tethyan belt, the Reko Diq mine has the potential to yield approximately 5.9 billion tonnes of ore, grading 0.41% copper and gold reserves amounting to 41.5 million oz. As of the latest knowledge, the ongoing disputes over the Reko Diq mining project need to be resolved for the full potential of this treasure trove to be realized.
