to add classification categories to individual domains on the block model. This is important where the categories overlap each other on the various domains and makes the resource reporting much easier.

<v Instructor>In this video, we will use the refined model</v>

[00:00:07.340]
to create a categorical model.

[00:00:09.370]
This is useful for where the volumes themselves

[00:00:11.550]
have not been created for only the domain you want to code.

[00:00:14.930]
In other words, they overlap each other,

[00:00:16.820]
as they were created independently.

[00:00:19.440]
For example, if you were classifying deposit

[00:00:21.540]
or using depletion volumes that had been extrapolated out,

[00:00:25.100]
and it was just expected then

[00:00:26.690]
that you would sort out the coding on the block model.

[00:00:29.380]
In this example here,

[00:00:30.520]
I’ve created some very crude indicated meshes

[00:00:34.280]
for the 2 domains that I’ve estimated.

[00:00:37.220]
So as you can see,

[00:00:38.670]
that they actually just overlap each other.

[00:00:41.330]
And because these domains are so close,

[00:00:43.890]
if I just use these as they were on the geological model,

[00:00:47.460]
I wouldn’t get the coding right.

[00:00:50.480]
So the way to do it, is to refine the geological model.

[00:00:53.610]
And then you can independently code each domain

[00:00:56.050]
with the relevant meshes.

[00:01:00.050]
So first, let’s make a copy of the geological model,

[00:01:02.860]
because when you do a refined model,

[00:01:04.320]
it’s going to do it, and set you on that model.

[00:01:06.930]
And I don’t necessarily want

[00:01:08.720]
this model completely refined. So copy.

[00:01:13.499]
(light upbeat music)

[00:01:16.610]
I’m just going to keep it as the GM copy.

[00:01:19.933]
(light upbeat music)

[00:01:23.370]
Then come back up to the geological model folder

[00:01:26.390]
and select new refined model.

[00:01:29.440]
Select the model to refine, which is my copy model,

[00:01:33.120]
the lithology I want to refine.

[00:01:35.000]
So I’ve got the granite diorite

[00:01:37.470]
and the portable free estimated.

[00:01:39.140]
So I’ll start with the granite diorite.

[00:01:41.770]
Then the base lithology column will be none

[00:01:44.130]
because we want to add our own code

[00:01:46.160]
and we don’t want to use the coding

[00:01:48.090]
from the drill holes.

[00:01:50.270]
And then I would just call this the classification model.

[00:01:53.675]
(light upbeat music)

[00:01:59.500]
So you can see it’s created the objects

[00:02:01.920]
for the granite diorite.

[00:02:03.890]
So now I need to come into lithologies

[00:02:06.270]
and add the classifications I want to use.

[00:02:09.250]
So I only have the indicated wire frame,

[00:02:12.490]
so I’m just going to have indicated and inferred.

[00:02:15.910]
So I need to add those too.

[00:02:18.769]
Inferred and indicated.

[00:02:22.679]
(light upbeat music)

[00:02:27.970]
When it come to surface chronology, new intrusion

[00:02:30.690]
because it’s a volume from surface.

[00:02:35.300]
This is the granite diorite first.

[00:02:38.020]
My first lithology will be indicated

[00:02:40.770]
and my second lithology will be inferred.

[00:02:46.070]
Need to activate that.

[00:02:50.580]
Come to the output volumes.

[00:02:53.948]
You can see indicated and inferred.

[00:02:58.130]
Next we’ll do the Quartz-porphyry.

[00:03:02.410]
So I come back here, refine lithology.

[00:03:06.681]
Quartz-porphyry, base lithology of none.

[00:03:10.031]
(light upbeat music)

[00:03:14.060]
I need to add any indicated and inferred again.

[00:03:17.145]
(light upbeat music)

[00:03:22.640]
So I can now use that coding.

[00:03:24.620]
(light upbeat music)

[00:03:26.900]
Surface chronology, new intrusion from surface.

[00:03:32.060]
Select the Quartz-porphyry indicated mesh.

[00:03:36.820]
First lithology indicated,

[00:03:39.020]
second lithology inferred.

[00:03:40.921]
(light upbeat music)

[00:03:45.540]
Activate.

[00:03:46.782]
(light upbeat music)

[00:03:54.610]
So now I should also have the indicated and inferred

[00:04:00.330]
for the portable free.

[00:04:03.400]
And now I just need to evaluate this onto my block model.

[00:04:07.440]
I’ll take the classification model I’ve made.

[00:04:11.130]
Evaluate that on.

[00:04:12.435]
(light upbeat music)

[00:04:19.660]
I can just check that’s coded correctly,

[00:04:23.117]
classification model.

[00:04:26.496]
I’ll subject thing of accept.

[00:04:28.986]
(light upbeat music)

[00:04:31.633]
That looks correct.

[00:04:34.910]
So now I can make a resource report,

[00:04:39.580]
using my classification.

[00:04:42.300]
Classification, Au.

[00:04:48.190]
I have to tell it the units.

[00:04:51.130]
Now I’ve got the invalid values

[00:04:53.240]
because there are blocks that don’t have an estimate.

[00:04:56.020]
So I can get rid of those just by creating a cutoff.

[00:05:00.680]
I’ll deselect the units I don’t want to report

[00:05:03.480]
because I haven’t estimated into them.

[00:05:06.140]
That’s only struck once from the original coding.

[00:05:13.730]
And now I’m going to group these

[00:05:15.280]
because I’m wanting indicators in for it, together.

[00:05:19.230]
Indicated and inferred.

[00:05:25.132]
(light upbeat music)

[00:05:29.508]
Cut these off.

[00:05:32.820]
Turn that to thousand troy ounces.

[00:05:37.990]
So now I have it coded by indicated

[00:05:41.210]
and inferred from my report,

[00:05:42.700]
which is great.

[00:05:43.533]
And then I can also use the pit,

[00:05:47.190]
filter that I had already created.

[00:05:50.520]
So in the calculations and filter chart,

[00:05:52.550]
it was the pit model I’ve evaluated

[00:05:54.260]
onto my block model,

[00:05:55.390]
messages inside the pit.

[00:05:56.790]
So you can use that.

[00:06:01.870]
Now, this is ready for me to copy

[00:06:04.200]
and paste into Excel or Word.

[00:06:09.590]
I hope you find that tip useful.
