Hole 1- From 8m to 501.4m [980 veins]
Weakly elevated magnetic response at depth."
Rockfire 1 Nov 2021 RNS
1200 copper veins in 1st 3 holes.
HOLE 2- 359M.
Visible chalcopyrite fluctuates dramaticcaly with some <1 vein and up to 8 veins/m.
HOLE 3- Coring
HOLE 4 -Price comments.
HOLE 5- DEEPEST EVER DRILLED.
HOLE 1-2: ASSAYS PENDING.
"Price: POTENTIAL OF A LARGE MINERAL PORPHYRY Copper/ Moly system."

Example: Racecourse, NSW, in Oz is aiming for 440Mt @0.44% cu eq.
Mr Bird thinks via a London 14.10.21 shareholder meeting that a major may pay 25-30p
because they have an agreement. No agreement may be less ? Mkt Cap £41.98m or 4.97p.
This is the copper example. However, Racecourse is near infrastructure so that is an advantage.
So, see how Rockfire and COPPERHEAD , Queensland will play out in terms of tonnage, grade and what the market will attribute for mkt cap to come.
Thur, 4 Nov 2021
For revisit:
Per oilmanmike at 16:09, Wed, 3 Nov 2021 he stated that Rockfire*s Copper Head project in Queensland, Australia is "BIGGER" than those 2 ie ALPALA.
Alpala MRE#3, 7 Apr 2020 RNS: 2.664 Bt @0.53% cu Eq.
High grade core 442Mt @1.44% cu.
COPPERHEAD, QLD, AUSTRALIA PER CARPENTARIA 1972
Non-compliant JORC 3 5 Mt @ 0.35% cu eq. It was tested on a 400m strike from recall?
Carpentaria did NOT DRILL DEEPER than 300m region.
STRIKE-COPPERHEAD
3km x 2km - see below from presentation.
Hypothesis: Even at max 3km strike , if everything CONSTANT ie grade 0.35% cu eq, depth 300m +- = 7x35= 245Mt [+-]
COPPERHEAD ----DEEPER THAN 500M?- PORPHYRY?
Rockfire per the RNS etc of recent days, think that there could be a PORPHYRY below 500m DEPTH. COPPERHEAD HAS NOT BEEN YET TESTED TO THIS DEPTH.
NO NEAROLOGY as Copperhead is on the coast of Queensland where there are no nearby mines.
-----------THE UNKNOWN------ONE CAN TELL WHEN DRILLING GOES TO DEPTH >500M-----
COPPERHEAD-DRILLING GOING ON
No assay results out yet. Only some cores shown and Mr Price, CEO*s short video shows him examining the cores from Copperhead in recent days.
News, Thur, 4 Nov 2021.
There was a discussion yesterday on the Rockfire main forum.
I quote from Rockfire*s Aug presentation:
"3km x 2 km soil ANOMALY. Pg 17/31
Open in all directions and potential exists for a SIGNIFICANT copper discovery.
5 drill holes in 1972 intersected visible COPPER minerals from SURFACE TO A DEPTH OF 300M."
==
Pg 19/31
"Drilling in 1972 tested a STRIKE OF 400M W I T H I N a 3km long and 2km wide SOIL ANOMALY."
Chart shows LONG SECTION LOOKING NORTH - A L L at various cu ppm."
==
Pg 20/31 " H E L I MA G survey - M A G N E T I C READINGS. UNEXPLORED NEW TARGET AREA."
Comment:
From the discussion yesterday, I think the notion that the WHOLE AREA is mineralised at ONE CONSTANT GRADE ie 2km x 500m depth x 0.4% cu is a simplistic type cals of extrapolation.
However, the Carpentaria non-compliant JORC in 1972 showed 35mt @0.35% cu eq over 400m
strike tested.
In reality, say, take an example like Racecourse, as drilling progresses, the drill holes DONT all produce 1 consistent grade NOR 1 intersection LENGTH for all the holes. Hence, why GEOLOGICAL modelling is inputted as drilling continues. Mr Colin Bird has pointed out for example that X Mt at 0.45% cu vs Y Mt at 0.35% cu = the AVERAGE grade lower, one will need to find more MT of ore.
So, "significant" as above does NOT yet mean the type of world class deposits ie Tier 1 of 1bn tonnes of ore.
However, in recent days, Mr Price, CEO of Rockfire has said there may be a PORPHYRY BELOW the current drilling >500m. Ah, that has NEVER BEEN TESTED BEFORE even in the past.
So, this is where it gets interesting in that what is THERE if any?
The DOWNHOLE data from current drilling will be insightful but as yet, no info released yet.
So, if this potential PORPHYRY does turn out , it will be DEEPER FROM 500m and then GRADES
will be of interest.
So, history awaits Copperhead. As I said yesterday, as and when the FIRST DRILL HOLE
from 500m is drilled, that will be INSIGHTFUL to see the grade. Thereafter, as norm, the next 2 holes will tell more.
Again, like Porvenir, the prospect does NOT produce ALL the SAME GRADES AND ALL THE SAME INTERSECTION LENGTHS and this was where only DRILLING can tell and
not MULTIPLY THE WHOLE POTENTIAL STRIKE X DEPTH X 1 GRADE.
News, 4 Nov 2021 [Thur]
Posting to re-visit in the later stages. Too early to tell when the current Rockfire drilling at Copperhead had not given out ASSAY RESULTS yet although the cores are of interest.
From Rockfire Resources website :
Copper Head
Copper Dome
Queensland, Australia. [Porphyry and noted by USGS]
"COPPER HEAD
Known as JULIVON CREEK
3km x 2km
2.8m x 800m Core Anomaly

Kindly check as I may have copied it wrongly re: 2.8m or is it 2.8km? I will check later.
COPPER DOME
Known as MOUNT LESLIE
EXPLORATION POTENTIAL VERY HIGH."
Previously, it was 2km x 1km
Now with new data, it is 4KM X 3. 5 KM.

Additional to 1st post below:
"Discovery of COPPER AT DEPTH looks particularly interest and could be indicative
of a LARGE SCALE PORPHYRY DEPOSIT >120,000/t COPPER [cu]."
My Comment:
In the latest recent Rockfire Resources RNS, the co said it was going to drill both Copper Head and Copper Dome, Qld, Australia shortly. SP ANGEL who is NOT the co broker commented and said in their conclusion that they are looking forward to the results ie coming drill. It is posted up on Twitter under #rockfire.
Also, the SIZE OF COPPER DOME HAS INCREASED - see my 1st two posts on this forum for details.
Copper Dome and Copper Head are south of Townsville, Qld, Australia and South of Mt Isa.
News, 21 May 2021
Copper is currently >US$10,000/t.

====EVIDENCE: "NEW BULL CHART PRICE, PORPHRIES NEARLY MINED OUT"======
From Mining.com, 14 May 2021
Link: https://www.mining.com/new-bull-chart-price-porphyries-nearly-mined-out/ 14.5.21
Gist:
80% of world copper supply comes from PORPHYRIES.
The authors studied some 115 co*s and their COPPER RESERVES HAVE INCREASED BY USING A CUT-OFF AT 0. 2 5 % COPPER F R O M 0. 4 % COPPER.
SUPPLY OF COPPER DEPLETING.
Thanks to 2020Upside for the link.
SO, FROM THE ACTUAL EVIDENCE OF THE DATA, THERE IS NO 1% COPPPER [CU] AS STATED AND REQUIRED BY 1 ON THE ROCKFIRE MAIN STOCK FORUM.
Other than Cadia-Ridgeway link below, the above is FURTHER EVIDENCE.
ROCKFIRE*S COPPER DOME, QLD, AUSTRALIA IS A PORPHYRY AND SO IS COPPER HEAD, QLD, AUSTRALIA.
Wed, 19 May 2021
----REF: EVIDENCE: C A D I A - R I D G E W A Y, LACHLAND FOLD, NSW, AUSTRALIA-LARGEST MINE IN AUSTRALIA------------
" 3 . 5 BT @ 0 . 2 6 % CU
& 0. 4 g/t au."
Cu=Copper
Au=Gold
Link: https://xtractresouces.com/bushranger-project/
--
SO, EVEN THE LARGEST MINE IN AUSTRALIA IE CADIA-RIDGEWAY DOES NOT HAVE 1% CU COPPER GRADE which has been mentioned on the ROCKFIRE RESOURCES main London South East ROCK forum as the required copper grade needed.
Just look up porphyries of which Cadia Ridgeway is classed as and one will find that in porphyries they tend to be of lower grades BUT HIGH TONNAGE.
So, one awaits the DRILLING OF COPPER DOME FIRST AND THEN COPPER HEAD as to how far the drilling will go down and at what grades etc.

----------------ROCKFIRE RESOURCES-Copper Dome, Queensland, Australia -------------
Drilling as said to start shortly but no date yet given in today*s RNS, Wed 19 May 2021
ROCKFIRE MAIN FORUM
It has been said that it has to be 1% cu copper by 1 poster.
REF:
[1]Racecourse Scoping Study [NSW, Australia]
At US$7,500/t copper price = 0.2% cu CUT-OFF ECONOMIC
At US$10,000/t copper price= 0.15% cu CUT-OFF ECONOMIC
[2]RIOTINTO WINU, Paterso, Western Australia
"28 July 2020: Inferred Mineral Resource, RioTinto at WINU
0.2 % CU CUT-OFF is 503 Mt @0.45% copper EQUIVALENT [Cu Eq]
and higher grade core 188Mt @0.68% cu eq, CUT OFF 0.45% cu eq.
ROCKFIRE CEO*S PRESENTATION
It was recent and it is available on Twitter on the #rockfire thread.
Mr David Price answered a shareholder*s question about the share price. This is common to all junior exploration co*s. The co drilling Racecourse, Lachlan Fold, NSW, Australia had a mkt cap of some £10m+ PRIOR to drilling the DEEPER resource. In recent times, the mkt cap went to £45m mark.
Rockfire Resources MKT CAP IS £10M PRIOR TO DRILLING COPPER DOME & COPPER HEAD, Queensland, Australia. Both these projects are listed in the USGS data.
So, from the data, the CELEBRATED BODA prospect, Lachlan Fold, NSW, Australia is also a porphyry but NO 1% cu overall or gold au 1% overall. From recall of the last broker report the grade is some 0.32 g/t au for the OVERALL prospect. The drilling also TESTED DEPTH. Given the Racecourse is also in the same area, they also DRILLED DEEPER and grades results are awaited for the next 5 holes.
Even WINU, the world class prospect cant produce 1% cu although this is a more shallow prospect.
SO, AWAIT DRILLING OF COPPER DOME 1st and then Copper Head, Qld, Australia.
Rockfire Resources has NEVER drilled a copper porphyry before so that is why it is of
INTEREST TO PORPHYRY investors given this is in AUSTRALIA, a TIER 1 JURISDICTION and 250km from the refinery as was said in the presentation.
Wed, 19 May 2021.
Rockfire Resources Plc: RNS 14 Apr 2021
"Geophysics"
COPPER DOME
"Previous drilling 1 of the 3 intrusions.
15m @0.9% cu
12m @0.6% cu
& 24m @0.3% cu copper.
Previous: 1KM X 2KM
New : 4 K M X 3 . 5 KM
20 holes to be drilled at all 3 intrusions over the next 6 months [reverse circulation drill].
==
My View/Idea:
The total 4km x 3.5km appears to be like BODA, NSW, Australia.
However, today*s RNS , 19 May 2021 shows the modelling of the 2 prospects at COPPERDOME which is 1.5km x 700m and 900m x 250m
Wed, 19 May 2021
BODA - one or two examples
KSD 010 851m @0.26 g/t from 293m.
However,BODA is more of a gold prospect as opposed to Rockfire*s Copper Dome which is more of a COPPER prospect so just an example but NOT an exact example. Will have to look further for another Australian copper porphyry example later if possible.
From today*s Rockfire Resources Plc RNS, Wed, 19 May 2021:
"C O P P E R D O M E - P o r p h y r y
-2 targets with modelling ------@500M BELOW SURFACE----
STRONG MAGNETIC RESPONSES being interpreted as magnetite alteration.

[2] 900M x 250M
Depth 600m to at least 1KM deep.
88m @0.23% cu & 75m @0.13% cu with most holes ending in copper mineralisation, PEAK 3.77% cu copper & 1.8g/t au gold."

HISTORIC: Rockfire RNS, 2 July 2018 [Thanks to Sniffer73 for the info on the main forum]
"35 mt @ 0/16% CU COPPER [Prior to JORC Code]. Internal.
=56,000t copper
Capertaria Exploration in 1988 has lifted the AVERAGE GRADE TO 0. 2 5 % cu copper."
My View/Idea:
The coming Copper Dome drilling in Queensland, Australia by Rockfire Resources plc looks just similar to the recent Racecourse [NSW, Australia] drilling. How? Racecourse also already had a resource estimate akin to COPPER DOME done by Carpentaria although NOT to JORC standard as above.
So, the drilling is TO TEST THE DEEPER MINERALISATION POTENTIAL akin to what was the objective in the Racecourse drilling & as norm for other deeper drilling targets @porphyries.
ROCKFIRE RESOURCES PLC MKT CAP : £10M MARK.
@0.95p-1p
I have been in for a while now as I am interested in Australian drilling of porphyries of COPPER targets.
THE TOTAL STRIKE LENGTH IS AROUND 2.5 KM [2 targets] at Copper Dome. It is 50km from Rockfire*s COPPER HEAD project, Qld, Australia.
Ref; "Rockfire Resources plc adds COPPER DOME option to its growing project list."
-Proactive Investors, 26.11.18
"Drilling took place in 1972 YIELDING GRADES UP TO 0.88% CU and some gold grades were measured."
==
Rockfire Resources plc has NOT STATED in today*s RNS as to HOW DEEP they intend to drill at COPPER DOME so look forward to details in the coming RNS*es to inform shareholders.
