How to Identify a Gold Bearing Area | Sciencing

Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better chance of finding desired amounts of gold.

How to Test a Rock for Gold | Sciencing

Take a rock that contains gold in it – this process works best on quartz rocks – and set it inside a glass jar. Add white cooking vinegar to the jar, covering the entire rock and then some with the vinegar. The acid-based vinegar slowly dissolves the quartz crystals surrounding the gold, leaving only bits of quartz attached to the gold. Other more potent acids, such as those used in
