Travelling Through Deep Time to Find Copper for a Clean Energy Future

 

More than 100 countries, including the United States and members of the European Union, have committed to net-zero carbon emissions by 2050. The world is going to need a lot of metal, particularly copper.

Recently, the International Energy Agency sounded the warning bell on the global supply of copper as the most widely used metal in renewable energy technologies. With Goldman Sachs predicting copper demand to grow up to 600% by 2030 and global supply becoming increasingly strained, it is clear we need to find new and large deposits of copper fast.

Getting this much copper will be impossible unless we discover significant new copper deposits. But there has been little exploration for copper over the past decade, as prices have been relatively low.

We have been developing software to model Earth in four dimensions to look deep inside the planet and back into the past to discover where copper deposits formed along ancient mountain ranges. This software, called GPlates, is a powerful four-dimensional information system for geologists.

How Large Copper Deposits Form

Many of the world’s richest copper deposits formed along volcanic mountain chains such as the Andes and the Rocky Mountains, in these regions, an oceanic tectonic plate and a continent collide, with the oceanic plate sinking under the edge of the continent in a process called subduction.

This process creates a variety of igneous rocks and copper deposits to form along the edge of the continent, at depths of between one and five kilometres in the crust, where hot magmatic fluids containing copper (and other elements) circulate within networks of faults. After millions of years of further plate movement and erosion, these treasures move close to the surface – ready to be discovered.

Searching for Copper

Geologists typically use a set of well-established tools to look for copper. These include geological mapping, geochemical sampling, geophysical surveys and remote sensing. However, this approach does not consider the origin of the magmatic fluids in space and time as the driver of copper formation.

We know these magmatic fluids come from the “mantle wedge”, a wedge-shaped piece of the mantle between the two plates that is fed by oceanic fluids escaping from the downgoing plate. The oceanic plate heats up on its way down, releasing fluids that rise into the overlying continental crust, which in turn drives volcanic activity at the surface and the accumulation of metals such as copper.

Copper deposits tend to form above subduction zones along
volcanic chains. This schematic is not to scale.

 

Differences in how subduction occurs and the characteristics of the oceanic plate may hold the secret to better understanding where and when copper deposits form. However, this information is traditionally not used in copper exploration.

 

Building a Virtual Earth

At the EarthByte research group, we are building a virtual Earth powered by our GPlates plate tectonic software, which lets us look deep below the surface and travel back in time. One of its many applications is to understand where copper deposits have formed along mountain belts.

In a recent paper, we outline how it works. We focus on the past 80 million years because most of the known economic copper deposits along mountain belts formed during this period. This period is also most accurate for our models.

We used machine learning to find links between known copper deposits along mountain belts and the evolution of the associated subduction zone. Our model looks at several different subduction zone parameters and determines how important each one is in terms of association with known ore deposits.

 

 

So what turns out to be important? How fast the plates are moving towards each other, how much calcium carbonate is contained in the subducting crust and in deep-sea sediments, how old and thick the subducting plate is, and how far it is to the nearest edge of a subduction zone.

Using our machine learning approach, we can look at different parts of the world and see whether they would have experienced conditions conducive to forming copper deposits at different times. We identified several candidate regions in the US, including in central Alaska, southern Nevada, southern California and Arizona, and numerous regions in Mexico, Chile, Peru and Ecuador.

Knowing when copper ore deposits may have formed is important, as it helps explorers to focus their efforts on rocks of particular ages. In addition, it reveals how much time given deposits might have had to move closer to the surface.

Australia has similar deposits, including the Cadia copper-gold district in New South Wales. However, these rocks are significantly older (roughly 460 million to 430 million years old) and require virtual Earth models to look much further back in time than those applied to the Americas.

 

The Future of Mineral Exploration

Finding 10 million tonnes of copper by 2030 – the equivalent of eight of the largest copper deposits that we mine today – presents an enormous challenge.

With support over a decade from AuScope and the National Collaborative Research Infrastructure Strategy (NCRIS), we are in a position to imagine tackling this challenge. By supercharging GPlates in Australia’s Downward Looking Telescope, together with AI and supercomputing, we can meet it head on.

These emerging technologies are increasingly being used by Australian startups like Lithodat and DeeperX and mining companies in collaboration with universities to develop AI’s enormous potential for critical minerals discovery.

Aurania Provides Update on Drilling at Tsenken and Tiria-Shimpia Targets

 

Toronto, Ontario, August 19, 2021 – Aurania Resources Ltd. (TSXV: ARU) (OTCQB: AUIAF) (Frankfurt: 20Q) (“Aurania” or the “Company”) reports that drilling at the Tsenken N1 target has intersected sediment-hosted copper mineralization visible over approximately 2 metres (“m”) and has also intersected salt, a key element of sediment-hosted copper mineralized systems.  Scout drilling continues for sediment-hosted copper at Tsenken N1 and for silver-zinc at Tiria-Shimpia in the Company’s Lost Cities – Cutucu Project (“Project”) in southeastern Ecuador.

Aurania’s Chairman and CEO, Dr. Keith Barron commented, “We recognized early on that the copper-silver within the Project is of Kupferschiefer style, and this was confirmed by Professor Gregor Borg, an international expert on the subject.  Essentially, what we have are multiple levels of sandstone with organic plant material which is now carbon in the Jurassic-aged Chapiza Formation.  This geological formation is mostly comprised of “red bed” sediments and is analogous to the Rotliegendes (in German “underlying red”) found beneath the Kupferschiefer in Poland and Germany.  The carbon in the Chapiza has acted as a chemical reductant, causing the dissolved copper to fall out of solution where oxidized, copper-charged groundwaters come in contact with the carbon.  At this point we still do not know the grade and thickness of these copper and silver mineralized carbon beds, nor how many individual stacked beds occur on our concessions.  We do know through mapping that we are dealing with multiple beds. A presentation of key concepts will be made available shortly on Aurania’s website at www.aurania.com.”

Tsenken N1

Drill hole TSN1-007, which is still underway, intersected approximately 2m of bleached sandstone, composed of volcanic fragments, that contains disseminated copper mineralization in the form of green malachite (Cu₂CO₃(OH)₂) and black tenorite (CuO).  The volcanic sandstone contains carbonized plant fragments similar to the mineralized sandstone found at surface.  The mineralized interval has been sampled and the samples have been delivered to the lab in Cuenca in central Ecuador for preparation before despatch to Vancouver for analysis.  The intercept is at 157m down-hole and approximately 80m below surface (Figure 1).

Drill hole TSN1-006 ended in salt, which was intersected at a depth down-hole of about 600m, a little higher in the geological profile than anticipated (see Figure 2 in press release dated July 21, 2021).

Six drill holes have been completed for a total of 1859m and hole TSN1-007 is currently at a depth of approximately 350m.

Figure 1.  Vertical profile interpretation through the Tsenken N1 area showing the location of drill holes 1, 2 and 3 that tested for sediment-hosted copper-silver in red-beds beneath a lava seal.  Hole TSN1-006 intersected salt and hole TSN1-007 is testing for expected sediment-hosted copper in a similar position in the sedimentary layering as the silver-zinc mineralization at Tiria-Shimpia is located.  The fault system shown in red is suspected to have fed copper into the sediments in a similar way that it did zinc-silver into the Tiria-Shimpia area.  (Evap. is evaporite (salt) and Int. is intrusive such as a porphyry). 

Drilling at Tiria-Shimpia

Two drill holes have been completed at Tiria-Shimpia for a total of 762m, and hole SH-003 is underway at approximately 300m depth.  Weak silver-zinc mineralization was intersected in 7 sedimentary layers in hole SH-001 and results are awaited from hole 2.

August 17, 2021 – Toronto, Ontario –Palladium One Mining (“Palladium One” or the “Company”) (TSXV: PDM, FRA: 7N11, OTC: NKORF) is pleased to provide this corporate update which highlights the current exploration status of our two primary projects, namely the LK PGE-Cu-Ni Project in Finland and the Tyko Copper-Nickel Project in Ontario, Canada. In addition, we are pleased to provide the key objectives of the Company over the coming months.

“With a cash balance of $15 million (unaudited) as at July 31, 2021, the Company is well funded to advance planned activities for the foreseeable future.” said Derrick Weyrauch, President and CEO.

Key Objectives (Milestones)

LK Platinum Group Element-Copper-Nickel Project, Finland

1. Resource definition drilling at Kaukua and the western portion of Kaukua South (“Kaukua Areas”) is scheduled for completion mid-September 2021. (Figure 1)
2. A NI43-101 compliant resource estimate for the Haukiaho zone, located 10 kilometers south of Kaukua, is scheduled for completion in Q3 2021.
3. Phase II metallurgical testing of the Kaukau Areas is underway and scheduled for completion before year end.
4. An updated NI43-101 compliant resource for the Kaukua Areas is scheduled for completion at year end (December 2021/January 2022).
5. A Preliminary Economic Assessment (“PEA”) is planned for mid-2022.
6. Step out drilling targeting the recently announced Induced Polarization (IP) anomaly to the west of Kaukua is scheduled to be drill tested starting September 2021. (Figure 1) (see news release dated July 7, 2021).
7. Assay labs continue to struggle with timely delivery of results due to an industry wide high volume of activity.
8. Assay results for 38 drill holes remain outstanding, while results have been released for 78 drill holes.

Tyko Copper-Nickel Project, Ontario, Canada

1. Drilling has resumed on the Smoke Lake zone, following a major drill breakdown and early spring thaw.
   1. Four holes have been completed from a planned seven-hole program.
   2. The objective is to find the source of the high-grade mineralization which produced intersections up to 9.9% Ni_Eq over 3.8 metres at surface (8.2 % Ni, 2.9 % Cu, 0.1 % Co, 0.6 g/t Pd, 0.5 g/t Pt), (see press release January 19, 2021)
   3. Previously, 28 drill holes defined a shallow 350-meter mineralized strike length at the Smoke Lake zone.
   4. Exploration drilling is targeting:
      1. Down plunge extensions of known mineralization.
      2. A large inverted magnetic high located below the Smoke Lake zone (Figure 2) will be tested by a 900-meter geophysics platform hole. The magnetic high may represent a significant accumulation of ultramafic rocks, potentially representing the source of remobilized / injected massive sulphides found at surface.
      3. After completion of the 900-meter deep hole, a Borehole Electromagnetics (“BHEM”) survey is planned to help determine the possible presents of massive sulphide mineralization at depth.
2. A 3,100-line kilometer VTEM geophysics survey has been completed over the entire Tyko property, the results of which are expected shortly.
3. The summer field program is well underway, crews are on their second rotation and beginning to explore the newly expanded Tyko Property (see news release July 27, 2021).
   1. To date over 1,300 soil samples have been collected for analysis, while results are pending.

In addition, we are pleased to provide the key objectives of the Company over the coming months.

“With a cash balance of $15 million (unaudited) as at July 31, 2021, the Company is well funded to advance planned activities for the foreseeable future.” said Derrick Weyrauch, President and CEO.

Key Objectives (Milestones)

LK Platinum Group Element-Copper-Nickel Project, Finland

1. Resource definition drilling at Kaukua and the western portion of Kaukua South (“Kaukua Areas”) is scheduled for completion mid-September 2021. (Figure 1)
2. A NI43-101 compliant resource estimate for the Haukiaho zone, located 10 kilometers south of Kaukua, is scheduled for completion in Q3 2021.
3. Phase II metallurgical testing of the Kaukau Areas is underway and scheduled for completion before year end.
4. An updated NI43-101 compliant resource for the Kaukua Areas is scheduled for completion at year end (December 2021/January 2022).
5. A Preliminary Economic Assessment (“PEA”) is planned for mid-2022.
6. Step out drilling targeting the recently announced Induced Polarization (IP) anomaly to the west of Kaukua is scheduled to be drill tested starting September 2021. (Figure 1) (see news release dated July 7, 2021).
7. Assay labs continue to struggle with timely delivery of results due to an industry wide high volume of activity.
8. Assay results for 38 drill holes remain outstanding, while results have been released for 78 drill holes.

Tyko Copper-Nickel Project, Ontario, Canada

1. Drilling has resumed on the Smoke Lake zone, following a major drill breakdown and early spring thaw.
   1. Four holes have been completed from a planned seven-hole program.
   2. The objective is to find the source of the high-grade mineralization which produced intersections up to 9.9% Ni_Eq over 3.8 metres at surface (8.2 % Ni, 2.9 % Cu, 0.1 % Co, 0.6 g/t Pd, 0.5 g/t Pt), (see press release January 19, 2021)
   3. Previously, 28 drill holes defined a shallow 350-meter mineralized strike length at the Smoke Lake zone.

Sierra Metals Announces Update Of 10,000 Tonnes Per Day Positive Preliminary Economic Assessment Results To Now Include Iron Ore Production At Its Bolivar Mine In Mexico

 

TORONTO–(BUSINESS WIRE)– Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) (“Sierra Metals” or “the Company”) is pleased to report the results of an updated Preliminary Economic Assessment (“PEA”) regarding the Company’s Bolivar Mine, located in Chihuahua State, Mexico to now include iron ore concentrate production.

This PEA report was prepared as a National Instrument 43-101 Technical Report for Sierra Metals Inc. (“Sierra Metals”) by SRK Consulting (Canada) Inc. (“SRK”). The full technical report will be filed on SEDAR within 45 days of this news release.

Highlights of the PEA include:

• Updated After-tax Net Present Value (NPV): US$361 Million vs. US$283 Million previously at an 8% discount rate
• The incremental benefit includes iron ore production and increasing production to 10,000 TPD from 5,000 TPD is now estimated to have an after-tax NPV (@8%) of US$78.2 million, an IRR of 69.0% vs. an NPV of US$57.4 million, and an IRR of 27.9% previously reported
• Net After-tax Cash Flow: US$650 Million vs. US$521 Million previously
• Life of Mine & Sustaining Capital Cost: US$345 Million
• Total Operating Unit Cost: US$25.62/tonne and US$1.50/lb copper equivalent
• Average LOM Copper Grade 0.72%
• Average LOM Iron Ore Grade 13.5% from ROM ore, 15% from long term residues stockpile
• Copper Price Assumption US$3.05/lb
• Iron Ore Concentrate Price Assumption for 62% Fines US$75.90/DMT
• MineLife: 14 years based on existing Mineral Resource Estimate
• Life of Mine Copper Payable Production: 551 million pounds

Luis Marchese, CEO of Sierra Metals commented: “I am very encouraged by the results of this updated PEA now including iron ore production. As mentioned in the previous PEA published in October 2020, the value could be further increased by the potential sale of magnetite (iron ore) as a by-product. Today we are happy to report that we are confirming enhanced economics and improving the value of the Bolivar Mine. The economics in this PEA confirms the rationale for approving this project in April of this year, which is proceeding on a fast track basis.

Additional to the iron ore project, the plan is to profitably develop and grow the Bolivar Mine through accelerating staged increases to a production rate of 10,000 TPD in 2024 from today’s capacity of 5,000 TPD, based on current analysts consensus metal price estimates.

We are continuing with our strategy to increase the value of the Company on a per-share basis. This builds upon the demonstrated success we have shown with increases in our mineral resource base and working to improve the throughput at all mines. At the same time, we continue to use best practices to deal with the daily effects of COVID-19 on our workforce and communities. We expect these positive developments to improve profitability further and cash flow for the Company and all shareholders this coming year as well as in the future.”

Mineral Resource Estimate

The property is located in the Piedras Verdes District of Chihuahua State, Mexico, located approximately 250 kilometers southwest of the city of Chihuahua and consists of 14 mineral concessions (6,800 hectares). The Bolivar deposit is a Cu-Zn skarn and is one of many precious and base metal deposits of the Sierra Madre belt, which trends north-northwest across the states of Chihuahua, Durango, and Sonora in northwestern Mexico (Meinert, 2007). Mineralization exhibits strong stratigraphic control, and two stratigraphic horizons host the bulk of the mineralization: an upper calcic horizon, which predominantly hosts Zn-rich mineralization, and a lower dolomitic horizon, which predominantly hosts Cu-rich mineralization. In both cases, the highest grades are developed where structures and associated breccia zones cross these favorable horizons near skarn-marble contacts.

This PEA considers depleted measured, indicated, and inferred resources reported in 2019 by SRK and effective as of December 31, 2019. The results of this PEA shown in Table 1-1 are indicative of conceptual potential and are not definitive.

Mining Methodology

Bolivar is a producing operation. The primary mining method at Bolivar is underground room and pillar mining. Previous mining at Bolivar has sometimes used lower cost and more productive long hole stope mining in areas where the mineralized zones have a steeper dip angle. The mine plans are to undertake a geotechnical assessment program in 2020/2021 to expand the use of long-hole mining.

Mineral Processing

The Piedras Verdes Plant, located 5.1 kilometers from the Bolivar Mine, uses a conventional crushing-grinding-flotation circuit to recover mineralized ore and produce commercial-quality copper concentrates with silver and gold by-products credits. The mineralized ore is delivered from the mine to the plant in 18-tonne trucks. In addition, the mine is constructing an underground tunnel that will enable mineralized material to be delivered via underground truck transport to a portal adjacent to the mill. This development will eliminate the impact of bad weather on the current surface truck haulage system. In addition, it will provide a lower cost and more reliable method of delivering mineralized material to the plant.

Mineral processing and the recovery of the mineral are demonstrated, and copper, silver and gold recoveries are established at 88%, 78.7% and 62.43%, respectively.

The Piedras Verdes Plant’s current throughput capacity is 5,000 TPD. In line with proposed increases in mine output, the processing capacity at Piedras Verdes will increase to 10,000 TPD in 2024.

A new tailing storage facility (“TSF”) (herein referred to as “New TSF”) is to be located just to the west of the existing facility and has an expected life through 2025. The PEA considers the use of tailings as a backfill and has included the capital and operating costs for a backfill plant. Storing some of the tailings underground would increase the life of the New TSF, and potentially permit the removal of mineralized material pillars that are currently unrecoverable.

The overall Project infrastructure exists already and is functioning and adequate to support the mine and mill.

Economic Analysis

This PEA indicates an after-tax NPV of US$361million (using a discount rate of 8%) at 10,000 TPD (in 2024). The total operating cost for the life of mine is US$1,071 million, equating to a total operating cost of US$25.62 per tonne milled and US$1.50 per pound copper equivalent. Highlights of the PEA are provided in Table 1-2.
