April: the first full month in lockdown

I ended my posting of one month ago with an extract from Boris Johnson's letter to all households in UK:
"It's important for me to level with you - we know things will get worse before they get better."
With amazing and unfortunate prescience, a week later he was in intensive care, a victim of Covid-19, from which he has now recovered, thanks to the front-line NHS doctors and nurses who daily put their own lives at risk. By the Easter weekend, less than two weeks into the month, there were over 11,000 recorded Coronavirus hospital deaths in the UK, many of those who had succumbed being these very frontline workers.

(The Times, April 17th)
But amidst all the gloom there have been many uplifting examples of the human spirit, including that of Captain Tom Moore, the 99-year old WW2 veteran, who set off to walk 100 lengths of his garden before his 100th birthday, which he celebrated yesterday, with the ambitious aim of raising £1000 for the NHS. At the time of writing the amount raised is over £32 million!
This has been a month in which the word unprecedented has been almost overworked, and words such as furlough, which few people would have heard of before, became common parlance.
April was the first month where worldwide lockdown was imposed and towns and cities became ghost-towns. Walking through a deserted Falmouth on our sanctioned exercise has been an eerie experience, and almost deserted beaches an unprecedented sight.

These images are truly dystopian and I wonder if we will see a summer scene such as this in the next few months:

Cornwall is the most remote area of England, and it is that remoteness that has deterred invasion over the centuries, from Romans, Saxons and Normans. Now the modern invaders are the tourists, who flock to our stunning coastline and wide open spaces and provide a massive input to the local economy. However Coronavirus has changed our day to day lives and the government has called for the nation to stop all non essential travel in a bid to stop the spread of the disease that has so tragically claimed many lives in the UK, so the tourists who are normally welcomed are now being asked to remain at home.

Unfortunately not all have heeded this request, which puts unnecessary strain on the already overworked NHS staff at Cornwall's only one major hospital in Truro, and each Thursday evening residents have been coming outdoors to applaud the NHS and other front-line workers. It has been an emotional response, applause being joined by the horns of boats in Falmouth Bay, and the raucous call of the gulls.
Many people are now working from home where possible and social distancing has forced many mines around the world to temporarily close and declare force majeur on smelter contracts. Metal prices have decreased due to lack of demand, and even the price of "king copper" often used to measure the health of the mining industry, is only slowly recovering after a very sharp dip in early March. Copper is at the heart of green energy, lithium batteries containing over 50% copper, so a huge amount of extra copper will be required for the development of electric cars once production ramps up again sometime in the future.

There is also a growing awareness of something that has been known for centuries, that copper and its alloys have antibacterial, antiviral and anti-fungal properties, so the red metal is likely to be increasingly used in hospitals to replace stainless steel. It was reported in The New England Journal of Medicine in March that COVID-19 was “detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel". The reluctance to use copper may be based on perceived cost, but making and installing copper fittings is no more expensive than using materials such as stainless steel which, ironically, is considered easier to keep clean due to its bright surface.
Most major international conferences scheduled for this year have been either cancelled or postponed, and tomorrow Barbara and I were scheduled to fly back from Cape Town, after Comminution '20, which is now postponed to next April. Ironically 10 years ago Comminution '10 came within a whisker of being cancelled due to the volcanic eruption in Iceland, which led to the closure of most of the European airspace on the 3rd day of the conference and leaving many delegates stranded in Cape Town for several days. Ten years on, with most major airlines grounded during the month, many unfortunates found themselves stranded in various parts of the world, unable to make it back to their home countries for the foreseeable future.
April has been a surreal month, the likes of which we have never seen before, but it is likely to be just the beginning of a very long haul. Currently there have been over 26,000 Coronavirus related deaths in the UK, and last week the government's chief medical advisor, Prof. Chris Whitty, said "it is totally unrealistic to expect that life will suddenly return to normal soon." He said that the UK will have to live with some disruptive social measures for at least the rest of the year.
Boris Johnson returned to office this week to face an unenviable choice which will define his career - how to ease the nation from lockdown to safeguard the economy, balanced against a potential increased loss of lives due to a possible resurgence of the virus. And all this coping with sleepless nights with a new baby! In comparison negotiations on Brexit (remember?) must seem like a stroll in the park.
Let's see what May brings. These are unprecedented times indeed.
"We will get through it in the end but it might take time, but at the end of the day we shall all be okay again... the sun will shine on you again and the clouds will go away." Captain Tom Moore

Memories of Egypt and CMRDI

Today Barbara and I should have been on a plane to Cape Town for Comminution '20, with Jon and Amanda following tomorrow.  But unfortunately not to be; not only are conferences being postponed or cancelled worldwide, so is travel.
Travel has played a big part in my career, and I have been fortunate to have visited around 50 countries. I am often asked which I consider to be the most beautiful, or the most interesting. Cornwall is pretty high on either list, but in terms of sheer beauty I would have to say the Jungfrau region of Switzerland (MEI Blog 24 March 2019) is my favourite.
The most interesting, without a doubt is Egypt, which I have visited twice, both times thanks to the amazing generosity and hospitality of Cairo's Central Metallurgical Research and Development Institute (CMRDI).
In 1980 Camborne School of Mines had a visitor from CMRDI (sorry I can't remember who), who was impressed by the pilot plant which we had just put together to give students some early operating experience (MEI Blog 4 December 2010). Twelve months later I was invited to CMRDI to advise on their own fledgling pilot plant, and during my week long visit, I was taken to see the sights of Cairo, and the Pyramids at Giza (MEI Blog 13 December 2010), after which they kindly provided air tickets and accommodation for a fascinating trip to Luxor in Upper Egypt.  Luxor, on the east bank of the Nile, lies on the site of ancient Thebes, the pharaohs’ capital at the height of their power, during the 16th–11th centuries BC.
During my few days in Luxor I took a ferry across to the West Bank of the Nile, where a young Egyptian villager offered to take me down to the Valley of the Kings, which turned out to be a hair-raising journey by donkey on a very narrow path down the precipitous cliff to the tombs of the New Kingdom pharaohs. Only to find when we arrived, that the tombs had been closed for the day!
Fourteen years later, in 1995, Tawfik Refaat Boulos, Prof. of Mineral Technology at CMRDI invited me again to Cairo, this time with Barbara, a purely goodwill gesture, as I did not have to sing for my supper and we were also provided with a guide for our few days in Cairo, Kamel El-Shamy.

As in 1981, after Cairo, we were flown to Upper Egypt, first to Luxor, and then on to Aswan to see the awesome Abu Simbel temples of Rameses II, built in the 13th century BC. In an amazing feat of engineering the temples were relocated in 1968 on an artificial hill high above the Aswan High Dam reservoir. This was to prevent the complex being submerged during the creation of Lake Nasser, the massive artificial water reservoir formed after the building of the Aswan High Dam on the River Nile.

Egypt is truly magical and should be on the bucket list of anyone interested in ancient history. Unfortunately, I have totally lost touch with Prof. Boulos and would be grateful for any information on how I might contact him. And finally, a belated thank you to the staff of CMRDI for their wonderful hospitality all those years ago.

First calls for abstracts for Biomining '21 and Sustainable Minerals '21

We face a very uncertain future, but all being well MEI's conferences, postponed from June of this year, will be up and running in June of next year at Falmouth's National Maritime Museum.
Many of the original authors have opted to have their papers transferred to next year, but others have had to withdraw, so there is now a call for abstracts for Biomining '21, which will be held from June 21-22, and Sustainable Minerals '21 on June 23-24. Short abstracts should be submitted by the end of December.
We would like to express a special thanks to our original sponsors for staying with us and supporting next year's events.
Current Biomining '21 sponsors
Current Sustainable Minerals '21
Updates on the conferences will be at #Biomining21 and #SustainableMinerals21.

Roshan B. Bhappu 1926-2019

I heard this week of the passing of one of the oldest members of our profession, Roshan Bhappu, who was President and Founder of Mountain States R&D International, Inc, Arizona. I thank Toni Griffin, Website and Social Media Manager of the American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. (AIME) for advising me of the sad news, and for pointing out that shortly before his death Roshan was interviewed by AIME, the interview being available on YouTube
I first met Roshan in 1986 in Falmouth, when he presented a keynote lecture on the impact of strategic minerals on mineral processing developments at the 2-week NATO Advanced Study Institute ‘Mineral Processing at a Crossroads’.  I last caught up with him at the 2012 SME Annual Meeting in Seattle.
Seattle, 2012
Roshan Bhappu passed away in Tucson, AZ on December 28, 2019 at the age of 93. He was born in Mumbai (then Bombay), India on September 14, 1926 and received his Doctorate from Colorado School of Mines in 1953. He worked as the Senior Metallurgist at the Bureau of Mines (now the New Mexico Bureau of Geology and Mineral Resources) for 14 years and served as the head of the Department of Metallurgical Engineering at New Mexico Tech (NMT) from 1960 until 1972.
When Roshan left NMT in 1972, he joined Mountain States Engineers group. Mountain States R&D International, Inc. spun off as a separate company in 1987 with Roshan as founder and president, a position he held for the remainder of his career.
Over the course of his career, he worked on hundreds of mining projects spanning the extraction of base metals, precious metals, industrials minerals, coal, and uranium. His expertise included the pre-concentration of minerals using heavy media separation, heap and dump leaching, in-situ extraction of copper and uranium, and projects related to environmental considerations in the mining process.
He served as President for the Society for Mining, Metallurgy and Exploration (SME) in 1990, and the American Institute of Mining, Metallurgical and Petroleum Engineers in 1992. He received many honors recognizing his significant contributions to his field, including the Van Diest Gold Medal from the Colorado School of Mines in 1968 and the Mining and Metallurgical Society of America Gold Medal in 2010. He was a “Distinguished Member” and a “Legion of Honor” member of the SME. He held several patents and served as a consultant to the World Bank and the United Nations. He authored many books and technical papers, and was an advocate for science education.
In recognition of Dr. Bhappu’s commitment to science education and supporting geoscience students, the Dr. Roshan Boman Bhappu Bright Star Scholarship will be awarded in January 2021. The Bright Star Scholarship Program provides support for three undergraduate students who work on projects with scientists at the Bureau of Geology.

An exciting new polymetallic mineral deposit found in West Cornwall

Today would have seen the first of our summer Cornish Mining Sundowners at Falmouth's Chain Locker, which now lies deserted due to the Coronavirus lockdown.
I am sure that the conversation would have centred on the announcement by Canadian company Strongbow, the company behind the planned reopening of South Crofty tin mine, of another significant new discovery of high grade copper and tin at Strongbow’s United Downs exploration project. 
Strongbow completed the acquisition of the South Crofty mine plus additional mineral rights located in Cornwall in July 2016 and some of these mineral rights cover old mines that were historically worked for copper, tin, zinc, and tungsten. United Downs is located approximately five miles east of South Crofty and lies within the densely mined Gwennap district, which was the richest copper producing region in  the world in the 18th and early 19th centuries, and was referred to as “the richest square mile on earth” (MEI Blog 27 October 2018).
The Gwennap mining area today
Strongbow and local company Cornish Lithium have a mutually beneficial agreement to explore each other’s mineral rights. Cornish Lithium has the right to explore Strongbow’s mineral rights in Cornwall for lithium in brine occurrences while Strongbow retains the rights to any hard rock mineralisation.
In 2019 Cornish Lithium started to conduct diamond drill testing for lithium in brine at United Downs and the new discovery was made by Cornish Lithium who intersected semi-massive sulphide mineralisation between 90.6 and 105m depth, assaying 7.46% Cu, 1.19% Sn, and 0.15% Zn.
The mineralisation is of similar nature to that mined at Wheal Jane and Mount Wellington mines, located 1.5km to the east; and copper grades reflect recorded historical mine production from United Mines located approximately 200m to the south. All of the mineralisation exploited historically is related to either quartz veins or quartz-tourmaline veins hosted within “killas”, the local name for metasedimentary rocks that overlie granite intrusions.
The Wheal Jane mine was discovered and developed into a modern mine in the late 1960s, initially by Consolidated Goldfields, and thereafter by Rio Tinto Zinc.  Mining activities at Wheal Jane and Mount Wellington ceased in early 1991, due largely to the Tin Crisis of 1985, but processing of South Crofty ore continued until March 1998 when ongoing low tin prices forced its eventual closure.
As drilling proceeds we will no doubt learn of the extent of this deposit and whether it is large enough to have ore-body potential. Hopefully there will be more news at next month's 'virtual sundowner'.
