ALLUVIAL GOLD At Different Depths Today I'm going to take you out to the Maryborough Goldfields and show you a heap of interesting examples of alluvial gold mining, the features of which can vary a quite lot depending on the depth of the field. We're going to take a look at surfacing, gully workings, shallow underground workings, shallow sinking, and deep lead mining, which are all types of alluvial workings at different depths. Alluvial gold deposits are formed when gold is eroded from its source in a quartz reef, and then transported by water and gravity to a new location. The gold makes its way downhill over time until it is eventually deposited into a river, stream or gully. One of the most important things to keep in mind when thinking about gold, is that it's heavy - real heavy, and over time it makes its way deeper and deeper down in the ground, or in a riverbed, until it can't go any further - usually when it hits bedrock. The old miners in the gold rush called this the bottom. The gold sits in a layer on top of the bedrock, a layer which the old timers referred to as washdirt, washing stuff, or simply stuff. This rich layer could be anywhere from less than an inch to a few feet thick. Unless you were over in the incredible Gravel Pits at Ballarat, where the washing stuff was reported to be an astonishing thirteen feet thick! The depth of alluvial workings generally depends on one important factor - how deep that bedrock lies beneath the ground.

Informa Markets Jewellery Sustainability Awards 2024 by JWA (Jewellery World Awards) is a commendable global initiative recognizing and honoring outstanding sustainability efforts undertaken in the past three years by businesses of all sizes in the fine jewelry, gemstone and related industries. It gives organizations the opportunity to share and showcase the ESG (Environmental, Social and Governance) activities that drive their businesses. Going beyond day-to-day operations, these companies are being celebrated for their Environmental Stewardship, Social Empowerment, Manufacturing Innovation, Community Engagement or Sustainability Leadership. Submitting themselves in one or more of these categories will not only highlight a company’s activities in that field, but hopefully encourage and inspire others to make changes in their operations, if they haven’t already. Colored gemstones have traditionally been shrouded in mystery. Their fascinating origins, along with a dazzling array of rich vibrant colors and complicated chemistry, have captivated our interest for as long as human beings have adorned themselves with their beauty.     It’s undeniable that most colored gems hail from far-off and far-flung, little-known locations, which is also perhaps why we call them ‘exotic’. Until recently, and still, supply chains have remained opaque, regarding the environmental and human impact on mining, processing, and the distribution processes. Having had the privilege to witness some of these remote mining operations and processing facilities firsthand, I firmly believe that colored gemstones serve as a link between people and places.     In line with broader societal trends, there’s a growing demand from consumers for transparency regarding the origin and supply-chain of gemstones, diamonds and metals, and it’s incumbent upon us, as an industry, to make this information accessible beyond our trade circles, empowering consumers to make informed purchasing decisions. Ultimately, the care for our planet and its inhabitants should be at the forefront of our business endeavors, regardless of their scale.  I am inspired by individuals and companies alike, who go above and beyond their core ESG activities to not only support their own employees, but initiatives that will make a difference in our very complex world. Whether feeding thousands of school children every day, supporting technology in underserved areas, funding, building and running community centers and facilities, financing medical initiatives, protecting and restoring ecosystems, or championing diversity, equity and inclusion, these efforts deserve recognition and celebration!    Together let’s seize this opportunity to shine a spotlight on sustainability and making a meaningful impact on our world!

Emerita Discovers New Gold-Silver Rich Gossans at Its Nuevo Tintillo Project. High grade gold assay results have been received from sampling gossan mineralization which may represent underlying massive to semi-massive sulphide mineralization. The new mineralized zone is located approximately 1.5 km to the northwest of the historic Santa Flora copper mine and situated only approximately 5 km east of the famous Rio Tinto Mine property. According to Joaquin Merino, P.Geo., President of Emerita, “We see a very similar relationship at the Iberian Belt West Project, specifically the gold rich gossan that overlies La Romanera deposit and two parallel mineralized horizons. Work continues to further develop this exciting new prospect and prepare it for future drill testing. Nuevo Tintillo is a large and highly prospective land package situated between some of the best deposits in the Iberian Pyrite Belt.” https://lnkd.in/gbkP9CRi $EMO #gold #silver #copper #mining #spain #tsx

🌟 Transformative Workshop Experience Shared by Victoria! 🌟 We are thrilled to share an incredible testimonial from Victoria, who attended our workshop on the basics of responsible diamond mining: "From this workshop, I have learned lots of things because from the time the diamond mine was founded, our parents had the notion that corundum was the rock that is traveling with a diamond. They never knew that diamond came from the volcano and pull it up with no other rock with the diamond. So whatever they saw as corundum, they classified it as a diamond sample. Today I learned that the Mambo quartz is what we should call a diamond sample because it twists, goes along with the diamond in the rivers and streams, hits against one another, and is deposited where you find many diamonds. We've been thinking that diamond is heavier than rock, so when we did our mineral work, we cut (throw away) the rock on the surface. In this training, I was taught how to separate the rocks three times. That makes me know that rock and diamond have the same density. I never knew it, so each time we did diamond work, we threw the big diamonds away! I didn't know that diamonds don't have a magnet. I thank Diamonds for Peace for the knowledge they have passed on to me." A big thank you to Victoria for sharing her insights gained from the workshop! 🙌💎 Your journey in responsible diamond mining is an inspiration to us all. Let's continue learning and growing together! 💼🛠️ #DiamondMining #EmpowermentWorkshop #KnowledgeSharing
