“BENTONITE & BARITE IS OUR BUSINESS!” has an extensive infrastructure to efficiently service the demand of bentonite and barite minerals used in the oil exploration and drilling centers of south Texas and Mexico (Eagle Ford Shale Formation). Our headquarters is located in San Antonio, Texas. Some of our main operations and processes involve extracting, processing, packaging, transporting, importing, storing and supplying quality API spec. milled sodium bentonite gel, cat litter and barite (BaSO4).

Water treatment & sodium bentonite pond sealant clay. Granular crumbles or mesh 200 available. We extract, process, and manufacture minerals for wholesale in Texas.

Bentonite and Barite Wholesaler Supplier

We can supply milled barite from our pig tanks to load directly in hopper pneumatic trailers or in jumbo bags (super sacks) of 3,000 Lbs. We also carry a large inventory of milled sodium bentonite “Gel” that meets or exceeds API (American Petroleum Institute) specifications API 13A sec 9: The bentonite can be supplied in Jumbo Bags (super sacks) of 2,000 lbs. or three layer paper bags of 100 lbs or 50 lbs palletized and shrink wrapped.

We offer high yield bentonite & sodium bentonite for many applications as water treatment, pond water sealer, and water leaks.

If you need to seal your pond or water tank in your ranch we can supply excellent quality sodium bentonite by the ton, super sack, or 100 lbs bag.

For Texas ranchers needing pond sealer, we can deliver at our warehouse in Eagle Pass, TX or deliver directly to the final destination by pallet or truckload using local trucking and logistics company services.

Bentonite is the commercial name given to a whole range of clays having its origin since time immemorial. Bentonite clay is a product formed from volcanic ash. The US, France and Italy are the main producers of bentonite clay, but some other countries also have quality sodium bentonite mines. Due to the presence of numerous volcanoes, Fort Benton, Wyoming is the largest source of bentonite clay in the world. Bentonite clay expands significantly when water is added to it; that is why people use sodium bentonite pond sealant while constructing new ponds or repairing old ponds.

Our processed bentonite and barite is milled to 200 mesh and is available for immediate delivery from our Eagle Pass, TX and Laredo, TX locations.
Lone Star GTC is highly involved in the process and logistics of our minerals. We supervise every aspect, including the mining, milling, and loading of the product assuring our clients a high-quality product at a competitive price. We also offer quality cat litter bentonite, which is odor controlled, fast clumping, dust free, and easy to scoop, while being pet, planet, and people friendly. (Private label)

Many customers have used our clay to prevent water leaks, our 200 mesh is perfect to blend and mix with soil.

We also offer a granular gel and a top quality provider for bentonite used in the foundry industry of steel & iron, which is extremely water-absorbent clay that will dry melted iron.

History of Bentonite

Bentonite has been known to the mankind for quite a long time. Towards the end of the 19th century, W.C. Knight, an American geologist, identified water swelling clay in and around rocky formation near Fort Benton.

This clay was then given the name “mineral soap.” However, interest in bentonite increased during the 1920s when researchers called bentonite a whole range of clay, which mainly consist of mineral montmorillonite and with lesser amounts of some other minerals such as pyrite, feldspar, quartz, and calcite.

Important Properties of Bentonite

The density of bentonite ranges between 2.2 and 2.8 g/cm3 depending upon its quality and the presence of other minerals. When wet, the volume is expanded almost 13 times more than when it is dry and several times its dry mass in water (depending on the quality of the bentonite). This property of bentonite clay is favorable for filling small and large voids or spaces. Pond sealer bentonite acts as a barrier between the water and the surface preventing seepage of water, which is an essential requirement while constructing any body of water, like ponds, dams, wells, and lagoons.

Lab test results are available on every lot that we deliver / Custom packaging is available.


If transportation is needed, we can arrange for pickup and delivery with one of our business partners in the mineral logistics field.
Flatbed, dry box container, pneumatic trailers, or specialized transportation can be arranged. Primarily serving the south Texas area.


For all mud companies in the area: We can offer a 4.10 ~ 4.20 Specific API gravity (density) barite that can be sold in super sacks or loaded from our pig tanks which are available at both of our locations. Bentonite Perfobent API, Bentonite-P (sub API spec) or a High Yield Bentonite “Gel” is available by the truckload, partial load or by the pallet. Sodium bentonite clay applications include drilling fluids used to aid and maintain stability and composition of drilling mud used on boreholes for oil, water, and gas.


We have a team of experts with more than 50 years of experience working and doing businesses every day on the full process of extracting minerals at the mines, milling and selling bentonite and barite. Clients include various companies that work in the industry of drilling and fracking oil gas & water. We are now delivering our API bentonite and barite to many local Texas mud companies, water base, and oil base drilling mud fluids manufacturers, stimulation chemicals additives and also businesses like Pemex© in Mexico.
