Telfer currently operates two processing trains with a total capacity of ~22 Mtpa. The Havieron ore is
expected to be processed through a modified Telfer Train 2 Processing Plant which is expected to operate a single train at 6Mtpa rate on a campaign basis. The Plant modifications are expected to include magnetic separation within the flotation circuit to reduce the amount of pyrrhotite in the final Cu Concentrate and a carbon-in-leach (CIL) circuit on the flotation tail and cyanide detoxification circuit. The expected cost of the plant modifications is included in the project capital estimate. A single train operation provides optionality if higher mining rates are achieved from Havieron or through the extension of Telfer’s current mine life (i.e. Telfer ore can be run through the other train with the existing flowsheet).
Tailings from ore processed is anticipated to be deposited at the existing Telfer Tailings storage fascility.

Bismuth is the key deleterious element for the gold/copper concentrate product with potential smelter penalties incurred on the basis of bismuth content above a threshold level.
The impact of bismuth in concentrate is anticipated to be managed by mine sequencing and concentrate blending.

They’re going to manage the Bismuth content at Havieron probably by daily testing the ores in the Stopes and deciding in what order they will be removed from the mine and stored in the Run of Mill stock pile for loading to Telfer.

On train 2 at Telfer they are going to install magnetic removal of the pyrrhotite that contains the Bismuth.

When the copper concentrate is produced at Telfer they will blend the concentrate to make it’s Bismuth content is within certain parameters , so that it doesn’t incur penalties at the smelters.

Power is expected to be supplied to Havieron from Telfer’s existing gas power station via a 66 kilovolt (kV) overhead line running parallel to the nominated haul road corridor. Further opportunities to replace these with non-fossil fuel power generation are expected to be evaluated as part of the
Feasibility Study during the Forward Works Program.

I’m wondering what renewables they will be concentrating on in the Feasibility Study.
Solar and wind must be dead certs, I’m hoping for some element of green hydrogen to utilise excess power generation.

CJ you are a fine one to criticise you have not got anything right yet on this shorting phase.

“That’s not good enough Bamps”
Well you should have put yourself out to go and ask him then cos I did and that was his reply.
Why should he communicate to us on the situation, in fact how can he.
Some of his top holding shareholders are shorting their own stock to gain more, how can he say anything that will criticise them .
They may be playing with 20-50% of their own stock, probably just like what some individuals on here are doing, bringing their average down and gaining more stock.
You can’t suspend a share against what some of the highest shareholders are doing.
Shorters getting burnt I doubt that will happen, they will get the nod from someone in the know.
Have a look at ITM share price and see what a big institution at work shorting and buying back, far more dramatic than here.
Boards can’t speak out against their top shareholders could have disastrous effects

He has spoken, in London he said “they will have to buy them back” and grinned

Shaun said he wants to come back in June and meet shareholders again as he enjoyed the last one

I’ve been breaking down the volumes in those mining zones taking into account the grades in each.
I’ve only looked at the Western front and a couple of the Eastern fronts. I’m nearly up to the latest MRE total ounces.
My methods are what I can see from the results, the computer software for working out the Kriging boundaries is a far more complex method and a lot more accurate.
I’m probably within an estimate of +/-50% but if my calcs get anywhere the truth there could be 50-75% higher.
Kriging boundaries take into account economic valuations of the mineral composition of the ore which also includes the processing costs and transport etc so the value used is lower resulting in tighter boundaries.
We’ve already been told we will lose a large section of mineralised ore due to practicalities of the mining plan, I believe that to be 600,000 ton I might have misquoted that figure.
A lot of ifs and buts in the MRE figures but if the gold and copper prices rise substantially before production the Kriging boundaries will widen to take in more economical ore, increasing the total ounces.

Presentation on here demonstrating Ultra fine +

Ultra fine fraction geochemistry
A new technique being tested in WA
Revisiting already assayed material can pick out small particles even in sand dunes
“Traditional, near-surface geochemical techniques have been reasonably effective in mineral discovery but to explore in deeper transported cover and find new resources, as demanded by a growing global population, innovative methods are required. Recently, a new adaption of methods to extract the ultrafine fraction of soils and sediments, assay the geochemistry, and combine this with additional spectral and physicochemical properties (Noble et al. 2019) has shown some major benefits for Au and Cu exploration. This UltraFine+™ workflow uses less sample, provides more data and reduces the nugget effect for Au with solid reproducibility. Also, few samples are below detection limits for Au (0.5 ppb), even in dune sands, for example, because the technique avoids dilution from the bulk Si-rich matrix, concentrating clays and iron oxides that host most elements of exploration interest like Au. ”

A lot going on in the background that we are not aware of.

Swan 2021
“Significantly anomalous Au with Bi-Te-Sb pathfinder geochemistry intersected in SWD001 at the Swan target:
? 2.6m @ 0.19g/t Au from 35.4m AND 3m @ 0.19g/t Au from 430m in Swan hole SWD001, associated with broad zones of strongly anomalous Bi-Te-Sb pathfinders;
? Anomalous gold and pathfinders identified in three further holes at the Swan and Barbossa West prospects
? 7m @ 0.10g/t Au from 18m in Swan hole SWD003
? 1m @ 0.48g/t Au from 384m in Swan hole SWD002
? 1m @ 0.20g/t Au from 296m in Barbossa West hole BWD001
? Ground EM survey completed identifying eight promising EM conductor plates in four targets, including two plates adjacent to Swan hole SWD001 above, representing potential higher grade mineralisation proximal to the anomalism identified at Swan to date

Next Steps
? 2022 exploration drill programme designed to test ground EM conductors at Pearl, Swan and Swan East
? Surface geochemistry in suitable areas involving Ultra Fine Fraction geochemistry is planned
? Ongoing review of the 2020 airborne Electro-Magnetic survey, to identify further “Pearl” like
aerial EM anomalies for ground EM follow-up
? Further analysis of the drilling results from 2021, 2020 and integration into ongoing basin- wide geophysical and geological modelling to drive further targeting

I can all hear you saying we know all that, the results do not look impressive but look again gold and copper proximal to 4 new conductors.
All the other results we’ve had from Scallywag have been distal.
They are getting close !!!!!
They’re still modelling and adding info from 2020, they’re building a better picture of what’s there.

It might be 2 separate licences but this looks to be the southern end of a Blackhills dome, they could be connected
Imagine that exciting or what!
It looks like they’ve known about Pearl since 2020 and now looking for more.
What more do they know?
When are they going to drill these conductors? It’s May already !
Get on with it :)))

The Decline is progressing down towards the hard ground.
The hard ground layer will gradually rise up the sides as the Decline continues.
There will be less and less resin injection being used to the sides
The real progress in the cuts can’t start until the Decline’s roof is in the hard stuff and the resin injection is not required, that’s a time consuming exercise along with the reinforcement bars.
These bars and resin will still be needed until the hard rock is sufficient to take the length of the rock bolts.
When the rock bolts can be installed in the roof then the cuts will increase to 4-6m per shift

I hope we go it alone at Rudall, if they do jv with Fortesque you won’t get much info.
Exploration results Sept 21
“Exploration activity on the Australian copper-gold portfolio included the completion of airborne magnetic and electromagnetic surveys, a ground gravity survey and on-ground mapping and soil sampling over the Paterson and Rudall projects in Western Australia. “

That’s all I can find and no plans or anything else, so don’t moan too much about Newcrest.
Rio is just as hard to find info on Winu let alone their jv targets but they have published something.

Most of the licences to the SW of Havieron are long and are in a SE to NW direction, Fortesques however abutt the SE end of these licences and go from Rudall in the NE Southwestwards

Hi Baldylocks
Shaun said it was truckable to Telfer, it will be the same as Havieron.
Rudall will be funded from debt if they hit anything.
Shaun did say they were talking to other significant players.
Well conspiracy theory for tomorrow will be a joint venture with neighbours Fortesque, who have the adjacent licence to the SW

Hi Hydro
Yes went very quiet about Goliath, first hole struck gold , perhaps too deep, perhaps Saddlereef more advanced but why not go back to Goliath.
You need at least 2 holes to form some sort of model, a huge huge huge target and first hole struck gold.
Explanations please on a big postcard :))

Hi Mark
The train at Telfer will have to be altered to accommodate more recovery of different metals although nickel concentrate is a very similar process to copper concentrate.
The cobalt recovery is different though it needs electrolysis and will be done at the refiners and come back as a credit but it is easier to get from Nickel concentrate than copper.
Zinc lead could also be there but may not be retrievable
Bismuth will cause issues with the recovery factors and has already reduced the initial forecast of 95% down to 88% for gold.
Bismuth apparently causes the blue in the cobalt which goes on to tint windows and paints.
Cobalt is a trace element in vitamin B12

Where’s my apple Strudel :))

Hi Strudel
Morning lesson :))
Regarding Paddy’s comments on the base metals and Hydro’s remarks about nickel, well what do we know.
Firstly the historical MMI surveys picked up the base metals of copper, zinc, cobalt and nickel.
Zinc and nickel were only found as trace elements, high levels of copper and cobalt.
Cobalt is not found naturally due to oxygen in the air /ground and chlorine in the ocean .
It can be found in new meteorites attached to iron ores in its natural form.

The first few holes by Greatland itemised mainly gold, copper and cobalt also arsenic
Newcrest have indicated that the cobalt levels are variable and difficult to form Kriging boundaries to include in the resource.
Cobalt is difficult to be retrieved from copper ores.

Cobalt can be found in metallic iron rich compounds and also compounds with arsenic.
Cobalt is commonly found in nickel and copper sulphides.
The temperature of intrusive magmas is important in the formation of copper and nickel sulphides from iron rich magmas, hotter the temperature copper sulphides are formed.
The cooling rate of the magma also separates these 2 metals.
A high nickel content will have a low copper content and vice versa with cobalt fluctuating between the 2.

Quote from a web site I was looking at
“ The sediment­hosted copper deposits are formed when salt­bearing fluids flush metals, including copper and cobalt, out of oxidized (red) sediments; if the metal­bearing fluids then react with reduced (black) rock or oil or natural gas, they deposit minerals containing copper and cobalt. Magmatic nickel sulfide deposits form when a magnesium­ and iron­rich magma becomes saturated with sulfur. Metals in the magma, such as nickel and cobalt, may then move into a separate dense sulfide­rich fluid that sinks to the bottom of the magma chamber where the metal sulfides are then deposited.”

Havieron is a complicated ore body with numerous intrusions bringing in different chemical reactions and mineralisation.
From the above quote Havieron has the red sediments, it has the sulphur rich fluidation and an iron rich ore body.

Back to what could be in Havieron
Nickel has not been mentioned in the top 700-800m from surface
Copper is dominant in top sulphide zone.
Copper is weaker below these levels.
The Northern corridor has recently been found to contain high grade zones this starts from around 700m from surface. These zones are not high grade copper and contain actinolite breccia.
Actinolite breccia contains arsenic important for cobalt compounds.
Also contains high iron content

Nickel sulphides form at the base of magmas.
Suggestions that the nickel is in the Eastern breccia could be a reality.
My assumptions are that the Eastern breccia intrusion has intruded into and formed the northern corridor.

What I’m suggesting is the nickel is in the EB and NC
and more than likely in higher grades than what the copper values have been shown at.
Plus cobalt will be in be

Hi MH
Yes don’t write off Ernest Giles.
Newmont left behind valuable survey on Meadows and a target Northwestwards could be 2x 5m targets in that area and several 1m camps without looking at the Wishbone area in the NW(not the company our licence on EG. Some very good survey information came from that one but not from Newmont, MMI was particularly strong but the licence lapsed and Shaun reapplied for that bit.
Mostly gold targets at Meadows processing should be less complicated than with copper, so set up costs will be lower , crushing, grinding, gravity circuit and cyanide circuit.
It’s in the middle of nowhere except a road nearby, renewables for the mine and plant may be great way forward to a co2 free project.
With the Australian government under pressure recently from the Green opposition, renewables may have to be introduced generally

The question where to drill yesterday was out of 5 targets Rudall was omitted as still in application.
My number 1 now would be Ramses, classed as a high priority.
2km-2.5km diameter Havieron like target sat next to Fortesque licence.
The 700m is not cover that is the magnetic anomaly I think that is why they want to do the geophysics to help with the modelling before drilling.
Havieron and Tabletop, Goliath gravity anomalies were higher up above the magnetics.
Excited to be drilling that one at last.
