[00:00.40] The incumbent industry deals with this problem by ignoring it.

[00:04.39] They pick one possible answer and act like the other ones don't exist.

[00:07.84] And as a result, we design suboptimal mines, make suboptimal decisions, often mining unnecessary material.

[00:15.81] We've invented a different way.

[00:17.94] We collect all the possibilities consistent with the data measured, and we do this by simulating the physical response of each of the arrangement of rocks.

[00:26.44] We do this 10,000 times faster by training an AI to learn the relevant physics of the rock beneath, in the time it takes the conventional method to test one.

[00:37.06] That means we collect better data, we make better predictions of where to look next.

[00:43.70] So if you had a rock body and a rock body that's denser than material around it, you might drill through the middle of it.

[00:50.34] But if you have all the hundreds of thousands of possible solutions, the best thing you can do is to collect data where you're the most uncertain and rigorously eliminate as many possibilities as possible.

[01:02.03] This enables us to maximize the information we get for every dollar we spend, and we do this repeatedly so we can quantify our uncertainties.

[01:12.93] Even after we've made an ore body discovery, we still have to contend with this uncertainty.

[01:17.44] We have to define the size and shape of this ore body.

[01:20.63] Let me illustrate how difficult this is.

[01:23.28] So now, 1,000 meters below your feet, you drilled, you sampled the rock and you determined that it has five percent copper.

[01:31.25] So now you know, you've got your data point and your observation.

[01:34.44] Now, I ask you to make a prediction of the concentration of copper of the person sitting next to you.

[01:40.02] What would your prediction be and how confident would you be in your prediction?

[01:46.40] What about across the room?

[01:49.32] Think of any person across this room and try to predict 1,000 meters below them.

[01:53.57] What about in the next building or the next city?

[01:59.15] This is the vast challenge that we face.

[02:01.01] We've only sampled a tiny fraction of rock, collected several football fields apart from each other, for which we're trying to make predictions of all the rock properties in between.

[02:11.37] This technology has helped us move fast in Zambia, where I come from, to design and develop a mine based on our predictions for which we've only sampled a tiny fraction of rock.
