Ann: American Rare Earths - 1.43 Billion Tonne JORC Resource, page-9

Visualizing 1.4 billion tonnes can be challenging, as it is an enormous amount of weight. Here are some examples that might help you put this into perspective:

The weight of the Great Pyramid of Giza is estimated to be around 6 million tonnes. One could imagine 1.4 billion tonnes to be equivalent to the weight of 233 Great Pyramids of Giza.

A fully loaded Airbus A380, one of the largest passenger planes, weighs around 560 tonnes. One could imagine 1.4 billion tonnes to be equivalent to the weight of 2.5 million fully loaded Airbus A380 planes.

The largest cruise ship in the world, Symphony of the Seas, weighs around 228,000 tonnes. One could imagine 1.4 billion tonnes to be equivalent to the weight of over 6,100 Symphony of the Seas ships.

Mount Everest, the highest mountain in the world, is estimated to weigh around 357 billion tonnes. One could imagine 1.4 billion tonnes to be equivalent to around 0.4% of the weight of Mount Everest.

I hope these examples help you visualize the enormous amount of weight that 1.4 billion tonnes represents.
