One example of a flammable gas found underground is methane. It is produced by the decomposition of organic matter in the absence of oxygen and can be found in coal mines, landfills, and oil and natural gas reservoirs.
No Diamond mines in Missouri, there was volcanic activity and all the conditions exist for the formation of the diamonds but none have been found. There are many other types of mines in Missouri from Limestone to Lead.
One product of Holland Mines is sand and gravel. Holland Mines operates in many states and is a leader in the production of sand and gravel for building roads.
Some of the minerals found in the Derbyshire area include fluorspar, calcite, galena, sphalerite, and baryte. These minerals are often associated with the lead mining history of the region and can be found in various mines and quarries throughout Derbyshire.
Methane found in coal mines is typically referred to as coal mine methane (CMM). It is a byproduct of coal production and can be a safety hazard due to its flammability and potential for explosions. CMM can also be captured and utilized as a valuable energy source.
Oil and gas are both found in mines. Mines are found all over the world, including Alberta, Canada. There are also many mining locations in the middle east as well.
Methane gas is a deadly gas commonly found in mines. It is highly flammable and can pose risks of explosions if not properly managed. Mining operations must monitor methane levels to ensure worker safety.

Gold, Silver, Lead, Zinc, Oil and natural gas.
Galena (lead sulfide) is commonly found in silver-producing regions. In Mexico, the northern states of Zacatecas, Chihuahua and Durango are home to the largest mines of silver and lead found in that country, with 68% of the national production.
"Mines" is the simple subject and "are found" is the simple predicate in a passive voice.
