The Mamut Copper Mine near Ranau in the state of Sabah was once the largest open-pit mine in Malaysia and a primary pillar of the local economy during its operational years from 1975 to 1999. Geographically, the mine is situated in a spectacular highland region at approximately 1,500 meters above sea level, not far from Mount Kinabalu. During its peak, millions of tonnes of copper ore, along with gold and silver, were extracted here, making Malaysia a significant player in the global mining sector. The mining process required the excavation of a massive crater that permanently altered the landscape. Since the mine's closure in 1999, the site has become a symbol of environmental challenges, particularly through the phenomenon of acid mine drainage. The former pit has filled with rainwater, forming a turquoise-colored lake that is highly acidic. Today, access to the site is strictly restricted while continuous efforts are made to manage the ecological consequences of the large-scale resource extraction. The mine's history serves as a vital case study for the balance between economic development and environmental sustainability.

📋 Practical info
What is this place?
Once the most significant open-pit copper mining operation in Malaysia, this defunct site now stands as a dramatic testament to past industrial exploits, presenting a permanently altered and striking landscape in Sabah.
Visiting
While the area is officially abandoned, structured tourist visits are highly irregular and independent exploration is strongly discouraged due to ongoing environmental hazards, unstable terrain, and residual toxic water pools.
Where to view it
The sheer magnitude of the excavated crater and its surreal, vividly colored mineral lakes are best appreciated from specialized scenic flights or safely guided off-road viewpoints situated well above the actual mining pit.
Local products
There are naturally no active commercial products emerging from this abandoned wasteland, but nearby rural villages often sell unique local handicrafts, traditional textiles, and hearty mountain food to passing adventurers.
Active season
The eerie stillness of the monumental crater is a constant year-round presence, though the striking mineral colors of the stagnant water are most dramatically visible during the brighter, sunnier days of the dry season.
Nearby
The haunting desolation of this former industrial giant has a profound visual contrast to the pristine natural beauty of the bordering Kinabalu National Park and its lush, diverse mountainous hiking trails.
