0:04 The company's now ready to pull out the
0:06 wand of truth being the drill rig and
0:08 test these geohysical targets. We're
0:10 looking forward to see what comes out of
0:13 the drill hole. Uh my name is uh Dr.
0:15 Jason Meyers. Um I'm a director of
0:17 resource potentials. Um we're a
0:19 consulting uh firm based in Perth,
0:22 Western Australia. Uh we provide
0:24 primarily high-end geohysical data
0:27 processing, modeling and interpretation.
0:30 And we also love to integrate geology
0:32 and geocchemistry to help our clients
0:34 with their targeting. We've been
0:36 approached by first development to
0:39 assist them in their exploration uh in
0:42 the walal ba embayment or basin um in
0:44 the pillar region of uh western
0:47 Australia. uh FDR are exploring for an
0:52 analog to the Great Land Gold um Javier
0:54 gold copper deposit um which was
0:59 discovered in the uh 1990s around 1993
1:01 but uh has been more recently drilled
1:02 over the last two years and has turned
1:05 out to be a worldclass
1:07 um gold deposit that that is quickly
1:11 being developed. Um
1:14 um the walal bayment is runs in the same
1:17 uh neoprotoz geology extending from
1:20 havron and telur. Uh undercover the
1:22 walal bayment itself is is a deep
1:25 sedimentary trough um primarily filled
1:27 with ferorizoic sediments which have
1:29 been previously explored for oil and
1:31 gas. Um some shallow holes have been
1:33 drilled in the basin and on the flank of
1:36 the basin is a shelf uh still covered by
1:38 sediments but with the same bedrock
1:42 geology that hosts Havon and Teler uh
1:43 sitting undercover. Um there have been
1:46 very few drill holes in that part of the
1:48 world but it is closer to the main
1:52 northern highway and the coast in WA. uh
1:56 that um target area that FDR have first
1:59 development is uh primarily a magnetic
2:03 anomaly very similar to the anomaly uh
2:05 that led to the discovery of Havron. Uh
2:08 there's two other uh magnetic targets in
2:10 the same project area. One of them is
2:12 quite deep. We know that now from uh
2:14 reprocessing and interpretation of
2:16 seismic reflection data. Um but we know
2:20 that the cover sitting over this um the
2:21 strongest magnetic anomaly in FDR's
2:24 ground sits at about 600 meters of
2:26 cover. Uh it's a little bit deeper than
2:29 Havron which is at about um 450 on
2:31 average, 400 in the shallowest and
2:34 pushing 500 in the deeper part. Um
2:37 because FDR is exploring in a very
2:39 deeply buried um environment. This is
2:42 what we call you know deep exploration
2:44 or deep undercover exploration. have to
2:47 rely on as many technologies as possible
2:50 before testing targets with drilling.
2:53 So, we've gone through existing and open
2:55 file magnetic and gravity data sets and
2:57 and really pushed them to the limit to
2:59 pull as much information as we could out
3:03 of them and assess depth and geometry of
3:06 the source of these anomalies. Uh we've
3:08 reprocessed seismic data as my colleague
3:10 Nigel will talk about. we carried out
3:12 passive seismic and there's been some
3:14 recent reconnaissance activity um and
3:18 heritage uh clearing.
3:20 So, so the work that's been going in the
3:22 back on the background for the last six
3:25 months or more um the company's now
3:28 ready to pull out the wand of truth with
3:31 being the drill rig and and test these
3:33 geohysical targets uh that have this
3:35 similar geological setting.
3:36 >> Yeah. So just to give you a quick
3:38 rundown of resource potentials
3:40 involvement in this project. Um we
3:43 started an initial desktop study in in
3:46 quarter one of two 2021. We quickly
3:47 identified that there were some key
3:51 magnetic bullseye anomalies with similar
3:54 characteristics uh to Javieron. You know
3:57 similar shape similar amplitude
4:00 and uh maybe a little bit broader
4:02 possibly sitting a little bit deeper
4:04 below cover. similar appearance to
4:06 Javier on but in a similar structural
4:08 position to to Wu. So we're quickly
4:10 excited by one one target in particular
4:12 which we've called the main eastern
4:14 magnetic anomaly. You know based on the
4:17 the local and the regional geology we're
4:19 expecting this these magnetic sources to
4:23 sit uh several hundred meters below
4:26 phenoroic sedimentary cover sequence but
4:29 hosted within a prospective protozoic
4:31 bedrock geology. As part of this initial
4:33 study, it was just imaging processing
4:36 modeling and unconstrained 3D inversion
4:38 modeling to to give a rough idea of the
4:41 the depth below surface. So based on
4:43 that initial study, you know, for this
4:45 main eastern magnetic anomaly predicting
4:48 maybe 700 uh 600 to 700 meters below
4:51 surface, but really it's it's just a
4:52 rough guess at this stage and we needed
4:56 to do further study to try and constrain
4:58 uh the the depth to the target and give
5:02 a more realistic um drill proposal.
5:05 Okay. So a follow-up study that resource
5:07 potentials has carried out involved
5:09 making the most of historical
5:11 exploration data namely 2D reflection
5:15 seismic and uh acquiring new data over
5:19 the top of the the magnetic targets in
5:20 particular the main eastern magnetic
5:24 target in order to constrain uh updated
5:26 inversion modeling magnetic inversion
5:28 modeling. So to start with the the 2D
5:30 reflection seismic, we worked with uh
5:33 the WA government geological survey
5:36 to obtain that data uh convert it from a
5:39 tape format and and got it sent to bells
5:42 size on the east coast of Aussie to
5:45 reprocess the data and and uh provide us
5:48 with some uh depth converted sections.
5:50 So converting seismic data from time
5:53 domain into to depth domain and so that
5:55 we could interpret uh stratographic
5:57 layering within the cover sequence and
6:00 interpret the the depth to the protozoic
6:02 basement. Historical 2D reflection
6:04 seismic didn't cover the main magnetic
6:07 eastern target. And so we proposed and
6:10 uh carried out a lowcost and effective
6:12 non- ground disturbing uh passive
6:15 seismic method to estimate the thickness
6:17 of cover sediments.
6:19 So, so this uh was carried out by Atlas
6:21 Geo Physics and three survey lines
6:24 across the across key targets and
6:25 overlapping with the 2D reflection
6:29 seismic uh were carried out uh late last
6:32 year. So the aim of this data is to to
6:34 identify uh reflectors deep reflectors
6:36 within the cover sequence and relate
6:38 these to reflectors that we're seeing in
6:41 the 2D reflection seismic to integrate
6:44 these data and then predict uh predict
6:46 the depth to the basement in the area of
6:49 the the key magnetic targets. Okay. So
6:53 we're we're in later 2021 now. We've
6:55 we've reprocessed the 2D reflection
6:57 seismic. We've acquired and processed
6:59 the passive seismic and integrated these
7:03 data in 3D workspaces. Next step was to
7:05 carry out a constrained magnetic 3D
7:07 inversion modeling. You know, so
7:10 constraining the model the magnetic
7:12 model forcing that model to sit below
7:15 the interpreted uh uh basement top of
7:19 basement and uh through doing a
7:21 constrained inversion. And now we've now
7:22 got a much better understanding of the
7:24 depth of the target and we can see some
7:26 variation in the shape. You know, it's
7:29 likely uh the magnetic source is likely
7:32 composed of two loes
7:34 and uh that will use that information in
7:37 drill targeting and uh the depth to the
7:39 top of the source magnetic source is
7:42 likely around 800 m. Uh so a little bit
7:44 deeper than the initial uh unconstrained
7:46 inversion. So, so we've now been able to
7:50 um very uh cheaply and um you know with
7:52 with minimal work on the ground been
7:54 able to provide a much uh better
7:56 constrained target for drill targeting
7:58 and uh that's that's where I sort of
8:01 handed over my work and the the rest geo
8:03 team started to work with uh first
8:05 development to to assist with uh
