Gold from the African Sea

Source: Ron Struthers for Streetwise Reports 04/29/2018

Sector expert Ron Struthers describes the opportunities open to a small explorer operating offshore in gold-rich Ghana, and reflects on the upswing in oil prices.

Yet another signal that inflation and gold will go higher is the breakout in the oil price. This is a weekly chart and there was resistance at $55 and $60 per barrel. After going through $55, the price broke easily above $60. A lot of analysts have now been commenting about the inverted head-and-shoulders pattern, with the breakout above this last week. I expect we are now heading to $80 per barrel.

I would normally be suggesting some Canadian oil stocks but Canada has problems. Chiefly the U.S. no longer needs Canadian oil as they produce enough for themselves and refineries are full. Delays continue for all three major proposed oil pipelines from Western Canada: Kinder Morgan’s Trans Mountain expansion, Enbridge’s Line 3 replacement and TransCanada’s Keystone XL. As a result Canada has a lot of oil with no place to go. Our light oil is now discounted over $7 per barrel compared to prices shown above.

Higher energy prices will feed into inflation numbers and gold will also go higher because the US dollar will have to go lower. President Trump guarantees it with his “America First” policy, which will force the dollar to weaken.

The administration’s “irreconcilable” goals of cutting trade imbalances while funding a large fiscal stimulus program pose the biggest challenge to the international monetary system since the breakdown of the Bretton Woods agreement in the 1970s, George Saravelos, global cohead of FX research at Deutsche Bank, wrote in a note. The only way to resolve these conflicting objectives is via a weaker dollar, he said.

That’s because the U.S. will probably struggle to attract sufficient foreign capital to fund its twin deficits, and that lack of appetite will likely translate to more currency weakness, he said.

Gold will break to the upside soon, and a new bull market in the miners will be born. However, the timing will not matter for this gold explorer.

This is one of the most uniqueand could be the most profitablegold stock I have ever found. In gold mining, the waste rock and leach dumps are a cost, and also a hazard that needs to be managed. Could you imagine the benefit if the waste rock could be sold and generate revenues instead of costs?

That is one advantage for Hansa Resources Ltd. (HRL: TSX-V). Another factor is their exploration license area could hold one of the largest gold deposits in the world.

This opportunity has attracted some of the top mining engineers around the world, with Watts, Griffis and McOuat, Canada’s longest-running independent geological and mining firm being retained, along with Royal IHC.

Royal IHC is a world leader when it comes to doing any work offshore and near-shore. There are piles of YouTube videos on IHC equipment, but this is a good corporate video showing what they do.

Offshore mining can be very successful. You might have heard of the TV show “Bering Sea Gold;” it dramatizes offshore mining by going into the remote, far North in a more severe climate. The same creators of the “Deadliest Catch” TV show and they only operate very small rigs. They do get gold from the ocean. A more realistic example is Debmarine, which is run by De Beers, the diamond leader. Debmarine accounts for more than half the total diamond production in Namibia, and 90% of the diamond deposits.

The waste rock that Hansa would produce is aggregate (sands/gravel), and offshore operations for this are well known in France, Belgium, Germany and Holland. In fact the UK gets 25% of its national gravel requirements from a fleet of 28 offshore aggregate dredgers.

On March 20, Hansa announced that it had entered into a Mineral Property Option Agreement with Poseidon Offshore Minerals Inc. Poseidon is a private company that Watts, Griffis and McOuat is behind in Toronto, Canada, with operations in Ghana, West Africa. Poseidon has applied for an offshore mineral reconnaissance license to explore for gold, diamonds, heavy minerals and aggregate in an area of 20,000 square kilometers on the continental shelf of Ghana. Poseidon granted to Hansa an exclusive option to acquire 60% of Poseidons direct and indirect interest in and to the license, which would represent a 54% interest in the license taking into account the interests of the government of Ghana. To earn the interest, Hansa will be required to fund work programs totaling US$4 million over the 36-month period following the effective date, of which US$100,000 has been paid.

The location of this license is what makes it so special. It is the only location in the world where three gold-bearing river systems enter the ocean in close proximity and on a shallow shelf.As a result, an enormous amount of alluvial gold has been transported into the offshore area. Ghana has been the #2 gold producer in Africa for the past several decades, and in recent years has been in the top 10 world producers. For many centuries, it was known as the Gold Coast. Government is mining-friendly and the industry is on the rise with government efforts to improve the business environment.

Ghana also has an acute shortage of aggregates because of Africa’s infrastructure boom, and to meet the growing demand for large infrastructure and urban housing programs along the heavily populated coastal areas of the country. This factor must not be overlooked. Sand and gravel from the offshore mining operations could greatly alleviate this shortage. Selling the sand and gravels could offset most or all of Hansa’s operational costs.

China is funding at least $18 billion in infrastructure development in exchange for commodity supply.

Under the agreement, funding will be made available through the Chinese Development Bank and will support the building of a 1,400-kilometer railway network to connect Ghanas Nyinahin and Kyebi bauxite mines to the new aluminum refinery, along with countrywide rail links. Ghana landed new financing from Russia. Last July the Ghana Railway Development Authority signed an MoU with Russian railway company Geoservice to build a 947-kilometer line from Accra to Paga, among other routes, on a build-operate-transfer basis.

This graphic shows the prolific gold mining with the three river systems flowing into the ocean.

The Poseidon Technical Team has a lot of experience in Ghana, leading the discovery of the Bogoso gold mine, the Damang gold mine and Tarkwa in Ghana, which are still in production 30 years later. These mines are currently producing about 800,000 ounces per year and are owned by major mining companies. Dr. Bob Griffis is the coauthor of the highly regarded Goldfields in Ghana, which in itself has led to numerous discoveries.

Hansa is led by CEO and chairman John Nugent, who practiced corporate and commercial law in Toronto prior to becoming an investment banker with Midland Doherty Ltd. After a period in senior management at Midland, Nugent became president of Gardiner Group Stock Brokers Inc., which was sold to the Toronto Dominion Bank. Nugent was a cofounder and president of Romanex Ltd, a mineral exploration company that acquired and developed properties in South America and Africa, which were sold to Sutton Resources Ltd., which was itself acquired by Barrick. He then became president of International Barytex Resources Ltd., a public mineral exploration company doing business in Canada and Tanzania.

This next graphic relates to the one above but shows the 20,000 square kilometers of licensed area.

Hansa is targeting 100,000 ounces per year of gold production, and ramping up to 500,000 ounces with additional dredges. In addition to gold, other heavy minerals of potential commercial interest include iron oxides (especially magnetite and hematite). In addition, titanium oxides (mainly rutile and ilmenite) are recovered in most heavy mineral sand operations, and can be used, in part, as a source for titanium metal but mainly for the very large titanium oxide pigment industry, which continues to grow at a substantial rate. Industrial diamonds could also be recovered.

As mentioned, aggregates from the dredging operations could also be sold.

However, before mining Hansa will have to conduct exploration programs to prove up resources and concentrations. This will be done much the same way it is done on land. Instead of driving trucks around, making roads and drill pads, Hansa will use a boat and float around doing the same thing. They take samples of sand and gravels from the ocean floor, drill into the bedrock beneath and conduct magnetic surveys. This graphic from their presentation shows how a geophysical survey would be done.

Hansa’s first phase exploration round will include the survey above, plus they have budgeted preliminary drill testing at 100 locations for $200,000. You might notice that drilling is quite inexpensive. They have also budgeted $50,000 for 50 dives to examine the seafloor further. They have also budgeted for metallurgical test work. There should be lots of news flow on these exploration results.

Financials:The company’s last financials reveal $1.16 million in cash and no long-term debt. Hansa is also completing a private placement of up to 40 million units priced at $0.05 per unit to raise proceeds of up to $2 million. Each unit is composed of one common share and one share purchase warrant. Each warrant is exercisable for an additional common share of Hansa at a price of $0.10 per share for 24 months.

Summary: “No where else on earth” is how Hansa titles its presentation, and that in itself is a great summary. There is no other opportunity like this anywhere else in the world. It is the only place in the world where three major river systems empty into the ocean from gold-bearing structures, and water depths are relatively shallow on the continental shelf.

The license application area is large, with multimillion ounce potential.

The use of water is a very efficient way to recover gold, and is used in many recovery systems around the world onshore. This is because gold is heavy and will not easily wash away.

Hansa anticipates that one dredge could recover 100,000 ounces per year, and they would eventually ramp up to 5 dredges producing 500,000 ounces per year. The next graphic is from the company presentation, listing comparable companies. I checked the junior companies that would be the best to compare to. Sheffield is a mineral sands explorer and has established a resource on two projects. Titanium is working on a process to recover heavy metals from oil sands. Image Resources has proven up heavy metal resources on projects in Australia.

I believe Hansa, with gold resources, would have more value than companies with heavy metal resources. Hansa could have heavy metals resources as well. The average market cap of the three juniors is $90 million, and I believe this is a valid target, which Hansa could reach in 2019. Once exploration begins and assuming it is successful, Hansa could be proving up their first resource numbers within 12 months. This offshore exploration can go much quicker on nice flat-water terrain compared to onshore, with hills, mountains and gorges, etc.

Considering the current financing there will be 97.4M shares out, and fully diluted 147.8M, if warrants and all options exercised. Current financing and exercise of warrants would certainly be enough funding to define measured and indicated resources.

· $90M / 97M shares = $0.93 per share · $90M / 148M shares = $0.61 per share

I believe these are reasonable targets if exploration proves successful; just how successful will determine where the price lands in this range. Do not rule out much higher valuations if exploration proves up good grades and large resources.

I did not include a chart here because this is a new deal, and there has been very little trading in the stock. Before it was halted, most days it did not trade at alland if it did, it was maybe 10,000 to 40,000 shares, and the odd day over 60,000. I expect liquidity will pick up around $0.10 per share, so we should be able to establish positions around this price.

Hansa Resources Recent price $0.06/share Shares out 57.4M; fully diluted 61.4M Post-financing shares out 97.4M; fully diluted 147.8M

Debmarine Namibia Annonuces To Invest In World’s First Ever Custom-Built Diamond Recovery Vessel

Debmarine Namibia announced that its Board of Directors have approved the construction of the world’s first ever custom-built diamond recovery vessel.

The new vessel is expected to cost US$468 million (N$7 billion) and represents the largest ever single investment in the marine diamond industry.

The ship will become the seventh vessel in the Debmarine Namibia fleet and is scheduled to start operations in 2022. On completion, the vessel is expected to add 500,000 carats annually to Debmarine Namibia’s production, an increase of approximately 35% on current production.

Following an extensive global tendering process, Damen Shipyards were selected to build the ship based on their strong track record for delivering quality vessels and their advanced technological capabilities. The new vessel will incorporate the latest marine technologies that will drive improved safety performance while optimising efficiency and utilisation rates.

Tom Alweendo, Minister of Mines and Energy, the Government of the Republic of Namibia, said: ��We note and appreciate the investment announced today by Debmarine Namibia. It is through investments like this we can continue to develop Namibia’s economy. As the Government we will continue to do what we can to promote and encourage investment in the mining sector.”

Bruce Cleaver, CEO De Beers Group, said: “Some of the highest quality diamonds in the world are found at sea off the Namibian coast. With this investment we will be able to optimise new technology to find and recover diamonds more efficiently and meet growing consumer demand across the globe.”

The new vessel is expected to create more than 160 new jobs alongside Debmarine Namibia’s current workforce of 975 employees.

ABB To Power The World’s Largest Diamond Recovery Vessel For De Beers

ABB will supply an integrated power system package that will ensure the world’s largest and most technologically advanced diamond recovery vessel meets exceptional safety, efficiency and availability requirements. The vessel is being built by Damen at Damen Shipyards Mangalia on the Black Sea in Romania. Financial details of the order were not disclosed.

With a total cost of $468 million, the vessel is the largest single investment ever made in the marine diamond industry. It deploys advanced subsea crawling – a technique for recovering diamonds from the seabed. The newbuild will be delivered to Debmarine Namibia, a joint venture between the Government of the Republic of Namibia and De Beers Group in 2022. De Beers Group is the world’s leading diamond company, with unrivalled expertise in the exploration, mining and marketing of rough diamonds, driving it forward since 1888.

Namibia has the richest known marine diamond deposits in the world, with Debmarine Namibia extracting some of the highest quality diamonds available anywhere from water of between 90-150 meters deep off the south west coast of the country. Traditionally, onshore along the coastline of Namibia, diamond mining is done in open-cast mines, however, with the land-based output in Namibia expected to run out in 15 years, offshore mining is on the rise.

The new 177-meter ship has been designed by renowned Norwegian naval architects Marin Teknikk. It will become the largest ship in the owner’s fleet, exceeding the size of Debmarine Namibia’s current largest vessel, the Mafuta, by 8,000 tons displacement (vessel weight based on the amount of water displaced by the hull). It is expected to increase the shipowner’s annual production by 35 percent, contributing additional 500,000 carats to today’s production levels.

The offshore mining specialist has previously installed ABB’s power systems on board the SS Nujoma (SSN), Debmarine Namibia’s deep-water diamond exploration and sampling vessel.

“The success of the SSN, with high reliability, efficient positioning and low fuel consumption coupled with safe operation, was instrumental in selecting the same systems for the new diamond recovery vessel, with ABB’s power systems being an integral part of the solution,” said Michael Curtis, who is heading the newbuild project for Debmarine Namibia.

The latest ABB technology will ensure that the vessel achieves unsurpassed uptime. In addition to the advanced system for power generation, distribution and variable speed drive propulsion systems, the solution includes a large online double-conversion marine uninterruptible power supply (MUPS) to support the ship’s vital control processes, significantly reducing the risk of critical power loss and downtime. ABB’s MUPS is designed for undisrupted availability, ensuring power backup for the vessel’s onboard control systems of the subsea-crawler and processing plant that sorts through sediment lifted from the seabed to extract diamonds. ABB’s advanced and tightly integrated power system will help optimize engine loading, as well as reduce running hours and fuel costs, and decrease maintenance needs.

“ABB is trusted globally as a leading technology company capable of delivering solutions for advanced and complex custom-built vessels. We are delighted to be working with them as part of a landmark newbuilding project for both companies,” said Mark Vermeulen managing director Damen Offshore & Transport.

“This is a truly special ship, packed with sophisticated technology, and a project demanding an especially close relationship with the customer to ensure that optimal solutions were delivered for exact specifications,” said Juha Koskela, Managing Director, ABB Marine & Ports. “We are thrilled to see that the team behind this advanced vessel recognizes the benefits of efficiency, safety and uptime available through integration. This success is also consistent with growing traction for ABB’s electric, digital and connected solutions across an increasing number of vessel types and operational profiles.”

Namibia in southwest Africa has 3,700 square miles of diamond concession at sea, which is expected to yield millions of carats of marine gemstones for the next five decades. CP Automation helped to mitigate harmful harmonics on onboard the prestigious Debmar Pacific diamond mining vessel.

Land-based diamonds in Namibia are expected to run out with the next decade. To avoid a shortage, the government of Namibia has been strengthening its offshore diamond mining capacity. In a joint venture between the Namibian government and De Beers Group, Debmarine Namibia, the country’s leading marine diamond mining company, was established in 2002. The company operates five diamond mining vessels including the Debmar Pacific, which mines diamonds from the ocean floor using advanced drill technology. Having been built in 1977, the Debmar Pacific was in urgent need of electrical system upgrading. Debmarine Namibia was having problems with a particular lighting circuit, in which several transformers were blowing due to suspected poor power quality supply. This is a classic symptom of an electrical circuit experiencing harmonic noise related problems. Actom Energy, electrical engineering specialist in South Africa, was chosen to design, manufacture and install an active harmonic filter control panel to the vessel to alleviate this problem. Actom needed to source a harmonic filter fast, and based on a recommendation from De Beers, called upon CP Automation. Using the information supplied by Actom and Deers, CP Automation advised the use of an ADF P100 active dynamic filter by Comsys. Why are harmonics a problem?

This problem generally arises from the use of variable frequency drives (VFDs) and other non-linear loads. A load is considered non-linear if its impedance changes with the applied voltage. This change means the current drawn by the non-linear load will not be sinusoidal, even when it is connected to a sinusoidal voltage. Non-sinusoidal loads contain harmonic currents that interact with the impedance of the power distribution system to create voltage distortion and power quality problems, which heat the transformer. This explains why the previous transformers broke in the lighting circuit on the Debmar Pacific. Harmonic filters — as the name suggests — remove harmonics. However, they also correct the phase of the fundamental currents, converting non-linear loads into linear ones. They cancel out the noise and keep the transformers cool and working efficiently. "We can’t stress enough how much of a positive impact the right harmonic filter can have on a company’s environmental performance, lowering energy consumption and improving productivity,” explained John Mitchell, business development manager at CP Automation. "With this in mind, we were confident the ADF P100 was a perfect match for Actom's project, and that it would put an end to the previous transformer issues." The ADF P100 active dynamic filter also brings the added benefits of a high-power density while being relatively small in size, which makes it ideal for small and medium size applications where space is precious, such as onboard a mining vessel. "We would certainly buy from CP Automation again," said Gregory Webb, instrumentation technician at Actom Energy. "Installing this filter was straight forward and engineer-friendly. It has continued to perform well since installation, as demonstrated by the lack of issues with the transformers in the lighting circuit, as we had seen before commissioning the harmonic filtering." The Debmar Pacific continues its operation off the southern coast of Namibia. To add to this fleet, the De Beers Group has since confirmed that the construction of the world's largest diamond mining vessel has commenced and will begin operation in 2021. This new vessel, along with the current Debmar fleet vessels, will make accessing the millions of carats of marine gemstones possible, with expert harmonic filtering onboard to ensure electrical systems are safe, trouble-free and long lasting. Namibia’s land-based diamond excavation may be reaching its end, but now, the country is taking diamond exploration offshore. With these vessels, the country can continue reaping the rewards of its lucrative diamond mining industry, without the limits of the land — or disruptive harmonics.
