Quartz is stronger than solid granite, which is rated at 6-7 on the Mohs hardness scale. Quartz features a 7-8 Mohs hardness which offers greater strength. This means quartz offers the same strength and durability as some of the hardest natural stone used for counters and other surfaces in the home.
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow.

Open pit mining. The process of excavating any near-surface ore deposit by means of an excavation or cut made at he surface, using one or more horizontal benches to extract the ore while dumping overburden and tailings at a dedicated disposal site outside the final pit boundary.

Extraction. Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.

Life of Mine plan extends to 2025, mining at over 11,000 tons per day at an average strip ratio of 0.88:1, based on the maiden Mineral Reserve (2021 Technical Report) Pre-tax NPV(5%) of $50.8 million and after-tax NPV(5%) of $45.3 million at $1,700 per ounce gold and $18.50 per ounce silver
Quartz can be extracted through open-pit mining. There are some rare instances that miners have to use explosives when it is necessary for them to expose the deep seam of the mineral. But it is done rarely because regardless of its hardness, it can be easily damaged when exposed to a sudden change in temperatures.
