Luo Chong's speculation was confirmed as soon as he saw the green patches near the base of the mountain—signs of malachite, an indicator of copper deposits. Anyone with a basic knowledge of chemistry would recognize that the green color often denotes the presence of copper, as seen in copper sulfate solutions.
Yunnan in China and Myanmar are famous for jadeite because these regions host acidic volcanoes like the Tengchong volcano in Yunnan. When these volcanoes erupted, copper sulfate solutions from the earth's core were expelled with the magma and, over millennia, seeped into surrounding rocks to form jadeite. Hence, theoretically, one could extract copper from smashed jadeite, although no one practically does this due to the cost.
Digging further around the area, Luo Chong discovered more blue-purple chalcopyrite, a natural crystal form of copper sulfide. The deposits displayed beautiful layers of indigo, deep blue, and purplish-blue radiating crystals resembling blue lingzhi mushrooms.
Crossing a small hill, Luo Chong encountered a vast expanse of white, which upon excavation proved to be a mix of minerals. The surface layer mostly consisted of kaolinite, also known as china clay, used for making porcelain or as a crucible for melting metals. Mixed within were limestone and translucent mica, with deeper layers revealing chalk and calcite, which are variants of limestone formed under high pressure.
Beyond the ridge of Treasure Mountain, the terrain was dominated by gray granite and adjacent tin deposits, evidenced by the silvery metallic sheen on the surface of the granite.
Having spent half a day exploring and digging, Luo Chong lay back on a granite rock, warmed by the sun, overseeing the blue antelope grazing nearby. He mentally thanked his university professors for their teachings in geology and chemistry, which enabled him to recognize and plan the utilization of these resources.
The day's survey confirmed the site as primarily a rich copper mine with various other minerals present as byproducts. Tin, found alongside the copper, could be alloyed to form bronze, the best metal currently accessible to Luo Chong.
Bronze, known for its durability and resistance to corrosion, has been used throughout history, from ancient weaponry to modern machinery bearings, illustrating its enduring utility. Despite the advent of iron, which gradually replaced bronze in weaponry during the Han dynasty, bronze's applications have persisted into modern times.
Given the abundance of minerals and the proximity of Treasure Mountain to his tribe—just a three-day walk—Luo Chong envisioned a prosperous future. He planned to build a bridge for easier access and use the blue antelope to transport mined ores, significantly reducing the travel time.
Satisfied with his plans and the potential of his discoveries, Luo Chong relaxed and enjoyed the scenic beauty around him. The east side of the mountain revealed a vast wetland extending beyond sight, an ideal habitat for diverse flora and fauna.
The wetland was lush with tall reeds, succulent alfalfa, and various herbs, all thriving in the moist soil—a perfect grazing ground for the antelope. Amidst this natural bounty, Luo Chong also noted the presence of a small herd of horses, although they were of little interest to him due to their size and utility compared to the robust blue antelope.
He spent the afternoon collecting grass seeds to cultivate near his dwelling, planning for the future sustenance of his tribe and livestock. Tired but fulfilled, Luo Chong prepared for another night at the base of Treasure Mountain, his mind already racing with plans for mining and agricultural development that would ensure the prosperity of his tribe for generations to come.
