What is Natural Pozzolan?
Natural pozzolan is an aggregate industrial material used principally as a replacement for coal fired fly ash and secondarily as a partial replacement for Portland cement in concrete. Natural pozzolan increases durability and reduces cost of concrete while providing a near 100% carbon offset. It is the green solution to harmful coal based concrete products.
Derived from volcanic ash, natural pozzolan was named after the Italian city Pozzouli located just outside Naples, where it was discovered and utilized by ancient Roman architects as a durable building material. Natural pozzolan has been used in projects ranging from the Pantheon of ancient Rome to modern engineering marvels like the Golden Gate Bridge and the Bonneville Dam.
Aggregate Industrial Material for Concrete
Today concrete is one of the most widely used materials in the world, however modern coal fired energy processes necessary in the production of Portland cement contribute large portions of greenhouse gases. As a result, over half of the coal fired plants have closed in the US reducing the supply of fly ash typically used in concrete and creating a demand for an alternative, natural pozzolan. As the supply of coal ash diminishes, natural pozzolan is becoming the mainstream choice for concrete producers.

Large Deposit of Volcanic Tuff
Our natural pozzolan deposit is a large deposit of volcanic tuff, up to 980 feet thick and over one mile in length. The tuff is a white, crystal-poor, unwelded rhyolitic tuff, tuff-breccia, and sediments containing two poorly welded , red to brown ash-flow tuffs.
Excellent Performance and Durability
A series of samples indicate the volcanic tuff has pozzolanic properties that meet or exceed ASTM C618 guidelines and has the potential for production of tens of millions of tons of natural pozzolan. An initial bulk sampling program of up to 36,500 tons has been permitted with the Nevada Division of Environmental Protection.
One Hundred Percent Carbon Offset
A supplementary cementitious material, as a replacement for coal fired fly ash and Portland cement in concrete, natural pozzolan provides a near 100% carbon offset and reduces embodied carbon in structures and slabs.
Historic Building Material
Discovered and utilized by ancient Roman architects as a durable building material with cementitious properties when mixed with water, natural pozzolan was used to build the Pantheon in Rome, the largest non-reinforced concrete dome ever built and still standing today.
Rana S. Gill, President
As CEO of GRG International Corp., Rana S. Gill has been instrumental in raising funds and negotiating acquisition of mineralized private patented land and staking new claims. Mr. Gill grew the property through private fundraising to acquire and stake land from an initial 0.5 square miles to over 4.5 square miles miles and recently oversaw the sale of land assets to a major publicly traded copper producer. Mr. Gill is a CA, CPA and earned his honorary Bachelor of Commerce degree at the University of Toronto.
Alan R. Coyner, Vice President
In 2014, Alan R. Coyner joined GRG as Director of External Relations assisting in private land acquisition, staking, permitting and assessing aggregates. With 45 Years as a Certified Professional Geologist, Mr. Coyner served as Administrator of the Division of Minerals for the State of Nevada and reported to the Commission on Mineral Resources and the Governor. Mr. Coyner has a B.S. in Geological Engineering from Michigan Technological University and a M.B.A. from the University of Nevada.
Hank Ohlin, Senior Exploration Geologist
Mr. Ohlin has worked as a professional geologist in the western U.S. for 40 years. He has performed geologic mapping and evaluation in support of geothermal, base and precious metals, and industrial mineral resources. Since 2006, he has focused on the Yerington mining district and surrounding west central Nevada. He attended the University of California, Santa Barbara and Mackey School of Mines, Reno, Nevada and is a member of the Geologic Society of Nevada and the Geologic Society of America.
