Hi Tropic,

Welcome!

TREO = Total Rare Earth Oxide. The term essentially refers to the sum total of REO in a deposit.

Rock chip sampling is a process of mineral exploration in which rock chip samples are taken from outcroppings, or exposed bedrock. These rock chips are then sent to a laboratory to determine their mineral makeup to help inform mineralization in the area.

There are different methods of rock chip sampling, each of which has different purposes and varying levels of accuracy.

• Chip sampling is used in early mineral exploration to determine if an area is of interest. In this process, several small rock fragments are collected over an area using a geologist’s hammer and chisel. These chips are composited into one sample and sent to a laboratory for testing. Typically, a geologist will high-grade this sample, looking for rock chips that have the best chance of containing the sought-after element. This method of testing isn’t used to provide a reasonable representation of the mineral makeup and abundance in the area, but rather to determine whether the area is of interest.
• Chip-Channel Sampling. This method of rock chip sampling is used when an interval that should be sampled can be identified in exposed rock. It attempts to define the approximate width and grade of the zone and the adjacent rocks by taking small, contiguous rock chip samples along the channel.
• Sawn-Rock Channel Sampling. The most accurate and objective form of rock chip sampling, sawn-rock channel samplings are cut from rock walls of a zone to test any mineralization. This type of sampling is most often used in a mine environment.

Rock chip sampling isimportant to the early exploration of a prospective mining area, helping to inform the mineral makeup of an area to determine whether it merits further exploration.

Hope that helps (copied and pasted from various online sources). Handy information to know if you're looking to invest in any mining co.
