Thanks for sharing fm. Alexander RIver and Big River are both going to be very strong cashflow gold mines.
It is a fantastic time for Brian Rodan and Paul Angus to be drilling out these high-grade stibnite enriched deposits, banking high grade gold for the Maiden JORC Resource release in the next 3 months.
The target at Alexander RIver down 500metres plunge (400metres from surface) is 589,000Oz at 6.5g/t. (Worth today $A1.472Billion)
The table below shows a higher target at 1,128,000Oz of gold 1,000metres down plunge, around down 800metres from surface, at Alexander River alone.
Let's see how close we get between the two deposits to the magic 1Million Oz at over 7g/t grade.
The current target of 125,000Oz of high grade gold 7-9g/t (worth today @ $A2,500/Oz $312Million) at Big River, is only made up of Shoot 4 in (coral).
Prima Donna (orange) and A2 Shoot (purple) have not been drilled or even touched by the old timers. We can quickly see new discoveries there between now and Christmas which would see the target ounces at Big River grow to 375,000-400,000Oz (worth $A937million) at 7-9g/t quickly.
As we get closer to the Maiden JORC Resource release and updates on the gold refinery scoping study, that's when the magic happens!
When you have over $A1.5Billion worth of near surface high grade gold that gets richer the deeper (because of the stibnite/antimony) you drill and your market cap is only $A29million, there is significant upside to Siren Gold.
Then we have the bi-product, stibnite/antimony that will help to reduce the already low cost of mining the gold via the stibnite/antimony by product sales.
Stibnite aka Antimony is also a critical material to a new battery material for grid storage energy, liquid metal batteries. China controls over 80-90% of the world's antimony/stibnite.
Antimony may be a renewable energy hero - Metal Tech News
An unsung war hero that saved countless American troops during World War II, an overlooked battery material that has played a pivotal role in storing electricity for more than 100 years, and a major ingredient in futuristic grid-scale energy storage, antimony is among the most important critical metalloids that most people have never heard of.
While antimony may not be part of the common lexicon, humans have been using this semi-metal for more than 5,000 years.
"For example, the ancient Egyptians and early Hindus used stibnite, which is the major ore mineral for antimony, to produce black eye makeup as early as about 3100 B.C.," the United States Geological Survey penned in a 2018 report on critical minerals.
While antimony's cosmetic status has waned over the past five millennia, the metalloid's ability to resist heat and corrosion, make stronger lead alloys, produce clearer glass for high-tech devices, and store renewable energy has created new uses for the ancient metal.
A wide array of American industries, including the defense and energy sectors, are taking advantage of antimony's unique properties.
"Today, antimony is used in lead-acid storage batteries for backup power and transportation; in chemicals, ceramics, and glass; in flame-retardant materials; and in heat stabilizers and plastics," according to the USGS.
Despite having significant reserves of stibnite, the U.S. depends on other countries, primarily China, for more than 80% of its supply of this critical mineral. The balance of American supply comes from recycling and refining concentrates imported from Italy, China, India, and Mexico.
"China continued to be the leading global antimony producer in 2020 and accounted for more than 52% of global mine production," USGS inked in its 2021 Mineral Commodity Summaries report.
Due to America's heavy reliance on imports, coupled with antimony's traditional and emerging applications, USGS recently ranked stibnite as the No. 10 most critical mineral to the U.S. when it comes to supply risk.
Idaho and Alaska have stepped up to meet America's strategic antimony needs in the past, and host rich deposits of the heat-resisting metal that could help fill current and future critical needs.
War hero
Antimony's flame and heat resistant properties elevated this metalloid to hero status during World War II.
This is largely due to the lives of countless American troops that were saved during the war by an antimony-based fireproofing compound that was applied to tents and vehicle covers.
When combined with a halogen – fluorine, chlorine, bromine, or iodine – antimony trioxide suppresses the spread of flames.
"Antimony is also vital to our military's effectiveness and has been since it was labeled as crucial to the war effort during World War II," U.S. Army Major General James (retired) "Spider" Marks penned in a 2020 column published in The Washington Times.
Over the eight decades since the end of World War II, antimony continues to save innumerable lives – from soldiers in the field to babies in the nursery – by lending its flame-resistant properties to mattresses, toys, electronic devices, aircraft, and automobile seat covers.
In addition to its widespread heat-resistance applications, antimony imparts increased hardness and mechanical strength into an alloy known as antimonial lead.
Bullets and shot, bearings, electrical cable sheathing, printing machines, solders, and pewter are among the products made of alloys that contain some amount of antimony.
The most common application for antimonial lead, however, is improving the plate strength and charging characteristics in the lead-acid batteries that have been used to start most internal-combustion-engine vehicles for more than a century.
Antimony is also used to make high-quality glass used by both civilians and soldiers. For example, a small amount of antimony oxide has the ability to remove bubbles and make super-clear glass used to make lenses for binoculars and similar optical equipment, as well as the glass screens of smartphones and other electronic devices.
"Antimony is a key ingredient in communication equipment, night vision goggles, explosives, ammunition, nuclear weapons, submarines, warships, optics, laser sighting, and much more," U.S. Army Major General Marks wrote.
The majority of this antimony is recycled, which accounts for essentially all of America's supply of the metal that is not imported.
Molten antimony battery
While lead-acid battery usage is expected to decline as electric motors take the place of ICE engines in the vehicles traveling global highways, antimony is finding its way into new applications in next-generation batteries that can efficiently store electricity at the grid scale.
Known as liquid-metal batteries, this relatively new form of energy storage was developed at the (MIT) in Cambridge.
Ambri, a battery research and development company born from the liquid metal battery research carried out at MIT, is advancing these large grid-scale batteries to commercial use.
The Ambri battery has a calcium alloy anode, a molten salt electrolyte, and an antimony cathode.
At room temperature, Ambri's cell is non-conductive and its materials are solid. Once heated to 500 degrees Celsius (932 degrees Fahrenheit), however, the minerals and metals melt and become active. The passing of ions through the electrolyte as the battery charges and discharges keeps the metals molten, eliminating the need for auxiliary heating or cooling.
All these liquids are stored in a single stainless-steel tank without the need for dividers because, like oil and water, they have different densities and do not mix.
Ambri says these batteries are less expensive to manufacture, work in a wider range of climatic conditions, last longer, and are safer than their lithium-ion counterparts.
While such batteries won't likely be used in vehicles, they could solve the problem of creating durable batteries for storing power from renewable sources such as solar and wind power – electricity that can be delivered to the grid as needed.
"Our technology will fundamentally change the way power-grids operate, increasing the contribution from renewable resources and reducing the need to build traditional power plants," Ambri says. "Customers will see lower electricity bills and more reliable service."
TerraScale, a data center development firm that prioritizes sustainability and cybersecurity, is leveraging these advantages through the installation of 250 megawatt-hours of Ambri liquid-metal batteries to store solar energy at its Energos Reno project in Nevada.
"Our data center technology partners are looking forward to deploying Ambri's technology to enable high-volume, reliable, and resilient energy storage with potentially the lowest levelized cost of storage in the industry," said TerraScale CEO Danny Hayes.
This is a major step in commercializing Ambri's energy storage technology and bolstering demand for the antimony that goes into its liquid-metal batteries.
