In December 2020 the Company announced that it had entered into an option agreement which gives the Company the exclusive right to explore and subsequently, if exploration is successful and at its sole discretion, acquire the mining claims over the area known as Glen Hume a property situated in the Gweru mining district in the Zimbabwe Midlands that has historically produced significant quantities of gold.

Caledonia believes that Glen Hume offers significant exploration potential. The agreement covers an area of approximately 350 hectares with substantial evidence of gold mineralisation including historical mining activity. Caledonia has conducted airborne geophysics which indicates attractive exploration targets and has also conducted preliminary metallurgical work indicating favourable grade and recovery.A preliminary contract has been signed with the existing drilling contractor and a drill programme has been put in place.

Caledonia has acquired the right to explore the area for a period of up to 15 months and subsequently, if exploration is successful and at its sole discretion, acquire the mining claims over the area. The total consideration is an initial payment of $2.5 million in cash, followed by a further payment of $2.5 million (payable in cash or shares at the discretion of the vendor) which would be payable should Caledonia decide to exercise its right to acquire the mining claims.

Caledonia has agreed to the payment of a one per cent net smelter royalty (NSR) to the vendor on gold it produces from the area. The NSR can subsequently be bought out at Caledonias discretion for a lump sum payment of $15 million within the first five years following the acquisition by Caledonia of the claims, or $10 million until the tenth anniversary of operation or $5 million thereafter.

In December 2020, shortly after the announcement of Glen Hume, the Company announced a further option agreement which gives the Company the exclusive right to explore and subsequently, if exploration is successful and at its sole discretion, acquire the mining claims overanarea known as Connemara North, a property which, like Glen Hume, is situated in the Gweru mining district in the Zimbabwe Midlands that has historically produced significant quantities of gold.

Connemara North is the northern section of the currently closed Connemara mine which was previously owned by First Quantum Minerals; it was placed on care and maintenance in 2001 and subsequently disposed of in 2003. It has not been commercially mined since this time but before being placed on care and maintenance the Connemara mine produced approximately 20,000 ounces of gold per annum from an open pit heap leach operation. Previous public disclosures made by First Quantum in 2001 indicated that they had plans to expand the existing open pit operations at Connemara mine, when gold prices were approximately $300/oz. At this stage it is not possible for Caledonia to verify any of the work performed by previous owners or to ascertain what proportion of any purported resource lay within the boundaries of the Connemara North property over which Caledonia has secured the option. The property is approximately 30km from Glen Hume with good road access between them offering the potential of operating synergies should Caledonia decide to develop both areas.

new to mining? here are the most common types of mining equipment

Working in the mining industry can be a dangerous place if you dont know what youre doing. Regular training is essential and understanding the machines youre working near or operating plays an important role in all aspects of the industry.

Each type of mining equipment comes with its own set of mining activities. The most common types of mining equipment vary depending whether the work is being carried out above or below ground or mining for gold, metals, coal or crude oil. From drilling machines to excavators, crushing and grinding equipment the mining industry comes complete with all the right tools. New to the job and want to find out what it all means? Heres a few of the industrys most common types of equipment and why theyre important for the job.

Probably one of the most common pieces of mining equipment, drills are an important part of the underground mining operation. Underground mining is carried out when rocks or minerals are located at a fair distance beneath the ground. But then they need to be brought to the surface. Underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material. Underground mining techniques have progressed significantly over the past years, including using remote controlled machinery.

Drills assist in creating holes descending underground. If miners are required to work underground, drills can also be used in ensuring the holes are large enough to serve as a portal for miners to enter. Directional drilling is also a type of mining technology where miners will use the tools and certain methods to drill wells.

Blasting tools are an essential part of the mining industry and are used to break down and fracture materials (usually rocks) by use of a calculated amount of explosive to liberate the sought-after product from the waste material. Blasting is also used to remove pockets of unwanted material that are preventing mining machines and personnel to get to the seam containing the materials of interest. Unmanned drill rigs will drill holes at pre-determined depths and positions on a blast face to ensure that a particular size fraction is achieved and that little of the overburden is liberated with the blasting to reduce material handling costs. Once this process has been completed, an excavator is used to recover the blasted rocks and other debris that has been dislodged during the blasting. The material is then conveyed to a central conveying system which will take it directly to the surface or via a skip and hoist system.

For above ground mining, earth movers are utilised regularly to carry loose soil and earth from one location to another. Earth movers play an important role in the mining industry because the equipment is specifically designed to work on large earth-moving and mining projects for a faster and more practical process. Used for digging, pushing and transporting the earth, they require the specialised skills of an operator.

Earth movers are heavy mining equipment that the industry would struggle to survive without and work hand in hand with bulldozers. Earth movers are normally used for removing overburden or waste material, which enables the excavators to remove the material or mineral of interest. Bulldozers are used to move this overburden material around to create a working surface for other equipment such as haul trucks and excavators.

As its name suggests, crushing equipment is used to crush rock and stone. Designed to achieve maximum productivity and high reduction rate, mining crushing equipment can come in a variety of different types for a range of jobs.

Crushing equipment is specially configured to break down the hard rock matter or gravel to a manageable size for transportation or conveying. They are valuable pieces of equipment in the industry because they reduce the costs associated with handling of larger sized material and also ensure efficient liberation of elements of interest in downstream processing of the material. In an opencast or strip mining operation, the run of mine (ROM) material is normally transported to the primary crusher by haul trucks, and in underground mining operations it is conveyed to the primary crusher. Crushing equipment is important to the mining process because it reduces the use of precious excavated resources and eliminates the amount of material on site.

Once the excavator transporter brings the raw material to the crusher for processing, the feeding device feeds the material into the crusher and in return the material is screened and all oversized material is recirculated back to the crusher to ensure correct size fraction is obtained. This weighbelt feeding equipment, usually referred to as Weighfeeders, conveys and controls the feedrate into the crusher to improve crusher efficiency.

Feeding and conveying equipment are necessary to the mining industry to move and control material flow within a mining and processing operation to facilitate efficient operation of equipment and determine operating rates and yields. In some instances secondary crushing is required prior to processing of the material. Once the material is at the correct size, fraction processing can occur which could include, milling, flotation, leaching etc.

Belt scale systems let you monitor production output and inventory, or regulate product loadout, while providing vital information for the effective management and efficient operation of your business. There are elemental crossbelt analyzers that provide real-time quality analysis of critical process streams to facilitate sorting, blending and out-of-seam dilution control. While materials are on the troughed belt conveyor, an automatic sampling system (which could be single or multi-stage) can take a representative sample directly from the moving material stream. (Take a look at this video to see how a sampling system works.) Weighbelt Feeders that convey and control feedrate accurately and reliably can reduce material consumption, help maintain blend consistency, and increase profits.

Flow measurement systems provide continuous, real-time flow measurement of free-falling materials or dense phase, pneumatically conveyed bulk solids, which is important to ensure and maintain product quality and process efficiency.

You make a great point about how drills are a very common piece of mining equipment. Choosing the right kind of drill tip can make a big difference in efficiency. Many drill bits will be tipped with synthetic diamonds to ensure that they are as durable as possible regardless of the rock and substrate involved. Thanks for your post.

It is true that working in the mining industry can be a dangerous place if we dont know about the machinery that are useful in mining industry. I hope your post will help people to know about the most common types of mining equipment and how to use them properly. Thanks

Thanks for the information. This really help to understand the different types of equipment you can expect to see in a mine. Drilling is such an important part to the mining process. Drilling and blasting go hand in hand to help break up the hard ground. After all you can gather the material your mining if you cant get to it.

Understating what type of mining equipment like core boxes, seems like a good place to start for beginners. Theres really now way to do a job properly unless youre familiar with the tools and equipment youll be using. It might also help with improving safety.

I AM ABOUT GOING IN TO MINING BUSINESS , ON MY RESEARCH ON HOW IT IS DONE BROUGHT ME TO THIS ARTICLE KUDOS TO Author Bios FOR THIS WONDERFUL HELP I GOT THROUGH UR POST AM GRATEFUL AND I NEED MORE GUIDE LINE TOWARD STONE MINING I AM CHIDI YOUNG

A new sensor fusion technique based on X-ray and 3D imaging promises improvements to the 3D modelling of mineral resources and more efficient sorting of precious metals. VTT Technical Research Centre of Finland Ltd (VTT) is coordinating the sensor development process through an EU project called X-Mine in collaboration with businesses, international research institutions and mining lobbies.

The European Commission has granted 9.3 million to a three year H2020 project coordinated by VTT called X-Mine, which develops new sensor technologies for mining companies drill core analyses and for efficient sorting of precious minerals and metals in ore. The X-Mine project also promotes more efficient 3D modelling of mining companies mineral resources, and thus improved recovery of precious minerals. The project combines products developed by various sensor manufacturers with commercial ore dressing equipment and aims to achieve sensor fusion that allows rock with low levels of minerals to be separated from the ore. The project reached its midway point at the turn of the year and is progressing gradually to the piloting of both drill core analysers and ore dressing equipment at mines during the spring of 2019. Two drill core analysers were adopted at mines in Greece and Sweden towards the end of 2018, and members of the project consortium are currently testing new sensors for ore dressing equipment and designing ore dressing algorithms. The project consortium consists of 15 research partners and businesses from around the world.

The project gives the participating research institutions and businesses an opportunity to develop sensor-based solutions for the mining industry together with experts specialising in the exploitation of ore resources, mineral processing and geological mapping. The consortiums aim is to develop solutions for efficient ore extraction and for reducing the amount of waste generated by the ore extraction process. All in all, the project is expected to reduce the harmful environmental impacts of mining by reducing the need for ore processing and chemical processing in mineral recovery. The project consortium is also looking to lower mining companies production costs.

The X-Mine project involves developing and piloting two prototypes to meet mining companies needs. Mining companies extract material from the bedrock in order to analyse the location of the ore and the volume of minerals and to estimate their mineral resources. The project consortium is hoping to increase the efficiency of ore exploration by developing equipment that can be used to scan drill core samples on site using new, highly sensitive layered imaging technology based on X-ray fluorescence as well as composition analyses. Analysing and scanning drill core samples on site speeds up the evaluation of ore resources.

The project also expects to improve the operation of automated mineral selectivity systems at the extraction stage by establishing a sensor fusion technique that combines X-ray transmission scanning along a line of highly sensitive sensors developed in the course of the project, X-ray fluorescence technology and 3D vision technology with rapid analyses with the help of efficient algorithms. More efficient ore dressing increases resource efficiency and mining companies profitability while reducing the harmful environmental impacts of mining.

The project was granted funding through the Horizon2020 instrument the EUs research and development programme that has 80 billion to award to European research initiatives over a seven-year period (between 2014 and 2020). The EUs H2020 funding programme promises more breakthroughs, discoveries and world-firsts by taking great ideas from the lab to the market. The total budget for the three year project is 11.9 million, of which 9.3 million comes from the EU.

The X-Mine project is based on international cooperation between research institutions from Finland (VTT), Sweden (Uppsala University, Geological Survey of Sweden) and Romania (Geological Institute of Romania) as well as sensor and equipment manufacturers from Finland (Advacam Oy), Poland (Antmicro Sp. z o. o. and Comex Polska Sp. z o. o), the Czech Republic (Advacam s.r.o.) and Sweden (Orexplore AB). End users involved in the project include mining companies in Bulgaria (Assarel Medet Jsc.), Greece (Hellas Gold S.A.), Cyprus (Hellenic Copper Mines Ltd) and Sweden (Lovisagruvan AB) as well as mining lobbies in Sweden (Bergskraft) and Australia (Swick Mining Services Ltd).

mining 101: ultimate list of gold mining equipment - precious metal info

mining 101: ultimate list of gold mining equipment - precious metal info

Found in Bulgaria are some of the oldest gold artifacts known to mankind, in the Varna Necropolis, a collection of graves built between 4700 and 4200 BC. This finding, dating back nearly 7000 years, provides evidence of the first civilization to use gold mining equipment. Some archeologists claim the Sakdrisi site in southern Georgia, which dates to roughly 4000 BC, is the worlds first gold mine.

In the 19th century, gold rushes occurred around the globe and people migrated to different regions hoping to strike it rich. The Victorian Gold Rush took place in Victoria, Australia, between 1851 and the late 1860s, and the Second Boer War took place in South Africa between 1899 and 1902. In America, the famous California Gold Rush took place in 1949, and discovery of Nevada's Carlin Trend,North America's largest gold depository,took placein 1961.

Since the beginning of civilization, humans have mined around 6 billions troy ounces of gold. Today, 2.5 percent of all gold production happens in Nevada, making it one of the primary regions on earth. As of 2017, China produced the most gold per year at 429 metric tons, followed by Australia, and then Russia. However, there's still a lot of gold out there, and you can join in the gold mining industry by investing in basic gold mining equipment.

There are two basic steps to gold mining: prospecting and production. "Prospecting" refers to the actual search in a certain area for valuable minerals, and "production," also known as mining, is the physical act of removing the gold from where you found it. Since different equipment exists for prospecting and mining, this article explores, briefly, equipment used for prospecting, and then focuses, primarily, on gold mining equipment.

How do you find gold? In the gold mining industry, theres a lot of value in learning from others who have gone before you. No one ever gets all the gold out of any one location. So, try going to where gold exists in abundance. Consider this: the California Gold Rush only removed a small percentage of the gold thats out there. That's right.

There are areas in California that are still open to recreational prospecting, including the Auburn State Recreation Area and the South Yuba Recreation lands. Once you get your feet wet in an area proven to have gold, you can move on to other areas closer to home. After mastering prospecting and gold-mining techniques, you might even want to look for gold in your own back yard.

Some people say, Gold is where you find it. What this means is you have to learn what to look for. First, understand that the way water moves in rivers and streams determines where gold deposits might settle. Next, you need to learn why gold concentrates in certain areas, and then search those areas.

Once youve selected a specific waterway for mining, youll want to pick specific points to search. Since it is impractical to search the entire stream or river, there are ways to read a waterway to determine the most likely places to find gold. The following describes how to find those places.

The first thing to know is gold is heavy. Its about 19 times heavier than the same amount of water and 6 times heavier than solid material found in streams and rivers. So, anything that slows the movement of water is likely to trap gold deposits. Things that slow down moving water are:

Water on the downriver side of obstacles will move slower, and this is where heavier gold will settle. When looking at a chosen waterway, begin by searching for natural dams where gold may have collected. Another place that collects heavier objects in a waterway is inside bends, places where water naturally slows down. Heavy objects will often form a bar at these points, and the upside of a bar inside bends is a great place to look for gold.

Once gold has settled in a stream, over time, it works its way down layers of soil and settles in bedrock. A great location for gold is in the material coating bedrock under a stream. Choose a location on the inside a bend where there is an obstruction and then dig to the bedrock. Sifting the soil coating bedrock, usually, will produce gold.

Learn to delay the excitement of seeing gold for the first time and you will have more gold-filled dirt to take home with you. Once you get better at choosing locations, and especially if you find a proven location, its best to spend your time digging and removing dirt, rather than sifting and cleaning it on site. Delay celebrating and get as much dirt as possible to take home. Once you get home, sift and clean the gold youve found.

Another great place to look for gold is in tall grass growing above an inside bend. Grass acts like a sieve and the largest gold pieces end up at the roots of grass. They often call this kind of gold oat gold. The pieces might be smaller than gold found in other places, but there could be a lot.

If you want to invest a little in your endeavor, you can purchase a metal detector designed to find gold. This gold mining equipment can cut down on the time spend hunting, but a mid-level detector can cost about $600.

When considering getting involved in gold prospecting and mining, make sure you learn and follow the rules. There are certain places where prospecting is legal and others where it is not. Many prospecting clubs exist and joining one can help ensure you are following rules. For examples, most sites require that you refill any holes you have dug, and that you do not destroy local plant life. Learn the rules before you head out with your gold mining equipment.

Once youve finished prospecting and have a location where you know there is gold, you will need gold mining equipment. What you use will depend on the size of your operation. If you are working in the gold industry, you will have industrial gold mining equipment. If you are mining on your own as a hobby, youll need smaller, personal gold mining equipment. Lets look at both.

If you want to use industrial mining equipment, make sure you have the proper training. If working for a business, they should provide needed training. However, if you purchased industrial gold mining equipment for a personal claim, be certain you know what you are doing. Safety should always come first.

Miners use drills for underground mining to create access holes for descending underground, or to place explosive charges to bring material to the surface. The drill miners choose depends on how and what is being mined.

Blasting tools create an explosion to blast away chunks of material to access minerals. Blasting can also remove chunks of unwanted materials that are keeping other machines or people from getting to a seam of wanted materials. In underground and open pit mines, miners use both drilling and blasting tools, often together. They use drills to place blasting tools at the right depth and in the right place.

Earth-moving machines move around large amounts of materials. They might haul material after blasting, move other materials allowing access to seams of minerals, dig underground mines, or get down to the bedrock where minerals might exist.

Crushing equipment moves materials around an underground mine. Miners use this equipment to keep the flow of materials going at an efficient rate, and to save money. It is easier to remove crushed rocks rather than heavy chunks, so crushing equipment saves time and effort.

A sluice box is a way to sift through raw material more quickly. Essentially, its automated panning. These machines used to be large and heavy in the early days of panning, but are now lightweight and easier to use. If youre serious about mining, they are worth checking out.

A higher quality sluice box, high banker boxes have a water pump allowing more material to move through faster. These boxes recycle water so you dont have to rely on water flow in the river. They recover more gold than basic models.

If you arent going into the professional gold mining industry, but are looking for a hobby or a part-time job to bring in a little extra money, consider joining a mining club to help you once you begin your prospecting journey. The club will help you learn about personal gold mining equipment, but, for now, lets take a quick look at what you will need.

There are lots of different sizes, colors, and options in gold pans. Essentially, a 14-inch plastic pan is the best size, by far. Color does not matter, however gold shows up better in black. Black sand shows up better in blue or green. There are many new kinds of pans, but a basic pan with sharp, undercut riffles is all you need. Make sure the bottom of the pan is as wide as possible to catch more gold.

You will need a place to store the gold you find. All you need is a waterproof container you can close tightly, such as a 35mm film container. You can purchase containers on the internet, specifically made for holding gold.

The last thing to consider is investing in Gold Lab, a personal system that recovers gold from the concentrate you have refined. A good gold panner can get most of the gold from refined dirt, but a Gold Lab kit will allow you to further refine and recover 100% of your gold.

Once you have your equipment, its time to get in the river to pan for gold. This simple technique mimics what the river does naturally. You recover material, or dirt and place it in the pan, from a river location where you think there might be gold. Then, you shake it in a left-to-right motion underwater to sweep away light materials while causing heavier materials to go to the bottom of the pan.

Take the pan with the riffles on the far side and shake it, vigorously, left and right. This breaks up materials sending heavier items to the bottom. Do not slosh water out of the pan. If you need to, repeat the previous step and break up larger chunks again.

Continue shaking the pan back and forth and keep removing the top layer of lighter materials until you are down to only the heaviest materials, such as coins, BBs, old bullets, buckshot, nails, garnets, black iron rocks and black sand. You should now be able to see gold in the pan when shaking and tilting it forward slightly.

Use a magnet to remove black sand and other metal objects. Keep removing things until only gold remains. Remove the larger gold pieces and save any leftover concentrate. Let it sit for a while so you can recover any remaining pieces of gold that settle.

If you have enjoy the outdoors, and have just a little ambition, you can make a hobby out of gold prospecting and mining. All you need are basic tools that as your gold mining equipment and the willingness to do a little research. Once you decide where to go, or join a mining club to help you find locations, pack up your tools and prospect. It may take practice at panning before you find anything, but once you do, youll love the feeling of satisfaction and discovery. If you find you enjoy the hobby, invest in semi-professional gold mining equipment and see if you can up the amount you discover. Even if you only discover a few flakes, prospecting can be a great way to make new friends, learn about the gold industry, and understand a little about gold prospectors of old. Its an inexpensive hobby, so grab basic gold mining equipment and get started today.
