About us

Our family owned marble mining company was started in 1991 shortly after my parents relocated from Canada to retire to their farm in the stony Northern hills of St. Ann, Jamaica.

My sister left the farm to work as a tax auditor and a social reporter with one of the island’s newspapers. I left to work as a News Editor with one of the island’s radio stations. That’s when I heard about a new stone exploration by the United Nations Development Program, UNDP.

Jamrock's Rare Marble Minerals

We took some of the stones from our stone crusher to the UNDP for testing. The UNDP's geologists spent months mapping, drilling and testing our rock stone. Their tests revealed that the deposit that we have dubbed, Jamrock Marble, has one of the world's purest marble deposits with as much as 99.51% calcium carbonate, CaCO3.

Some 20 years later we found out from another team of geologists that Jamrock has a large reserve of rare minerals that can help create healthier homes and a healthier planet by naturally destroying bacteria and air pollution while absorbing carbon dioxide. In 2013 geologists from one of the world's biggest lime/calcium oxide producing companies Lhoist collected and tested samples from Jamrock's deposit. Their samples revealed that Jamrock has a unique deposit of natural 98.6% "calcium oxide from marble" that contains food grade nickel, titanium dioxide, potassium oxide and sodium oxide. Jamrock's minerals and in particular its titanium dioxide provide an easy way to wash, sanitize and brighten buildings.

Jamrock's Antibacterial Minerals

Jamrock Marble's titanium dioxide, calcium oxide/lime and some of its other oxides are natural fungicides that instantly beautify and create white bright self-cleaning surfaces. Jamrock's natural blend of titanium and hydraulic marble lime absorb water and prevent bacteria, moisture, mold and mildew from forming on the surface and from within the building envelope.

Titanium dioxide and calcium oxide have excellent thermal qualities that quickly remove dampness and keep buildings warm when it's cold and cool when it's hot. This saves homeowners money by reducing the amount of energy they need to heat and cool their homes.

Jamrock's Carbon Absorbing Minerals

Jamrock Marble's line of coatings, Kings ET, is made from natural hydraulic marble lime. Like other hydraulic lime based coatings Kings ET absorbs more than 75% of its weight in carbon dioxide as it dries. So when you blend 5 pounds of ET with one gallon of water you will be helping the planet naturally capture more than 2.5 pounds of greenhouse gases as your coating cures.

Unlike other limes Jamrock Marble's lime does not have to go through any heavy carbon producing kiln burning to turn it into a lime because it is a natural lime. Mother Nature burned off ET’s carbon dioxide millions of years ago. This burning left ET with a high purity carbon absorbing marble deposit.

The carbon absorbing powers of ET’s minerals are activated when ET is blended with water, H2O. The water activates ET’s pharmaceutical grade potassium oxide, sodium oxide and calcium oxide. The chemical reaction transforms these oxides into potassium hydroxide, sodium hydroxide, and calcium hydroxide. These hydroxides are known to be three of the planet's best natural CO2 absorbers. Jamrock's oxides give Kings ET its carbon absorbing guarantee.

Anyone can easily and safely apply Jamrock's carbon absorbing coatings with water the same way lime wash is applied. But gloves should be used because ET like other white limes can dry out the moisture from your hands because it is caustic. ET Paints are currently available in white titanium marble lime or titanium and white lime blended with Jamrock's natural brown iron oxide pigment.


Jamrock's Future Plans

Our aim is to eventually list Jamrock Marble on Jamaica's Junior Stock Exchange as a low carbon mining company that produces innovative carbon negative Eco building supplies on a global basis. In 2016 Jamrock's founder received a Certificate of Recognition from the Prime Minister of Jamaica for the Scientific Research Council’s National Innovation Award for the application of its marble lime as a low carbon cement.
