25th July 2024 Visit to black granite lease area located in Battagram (Khyber Pakhtunkhwa - Pakistan) for the resource quality assessment. Black granite (dolerite) has been found in Hazara division abundantly in a few districts e.g. Mansehra, Battagram and Thakot (Allai). The extent of dolerite veins in all these areas is similar - primarily EW, however, little variations in shade and grain size is observable with the naked eye. Slates of Hazara region and Attock are often confused with dolerite as the naked eye observation of both rocks is confusingly similar. Dolerite is an igneous rock while slate is a metamorphic rock of sedimentary origin. I generally term slate as "pseudo-dolerite or pseudolerite" as it's only the look-alike of dolerite and may serve as black granite specially if it occurs in the form of boulders e.g. in Haripur the boulders are fine-grained but when polished with the same pads of dolerite (as per local industry practices), it gives a dull-polished look with apparent fine-grained texture. When the natural sheets (thin pieces separated along natural cleavage planes) of slates are cut and polished, it's difficult to differentiate between slate and dolerite. Btw I personally assessed the slates' boulders of Haripur and slates' sheets of Attock.

Mining Short Notes📝 WHAT IS THE DEFINATION OF A QUARRY? A quarry is a place where rocks, sand, or minerals are extracted from the surface of Earth. A quarry is a type of mine called an open-pit mine, because it is open to Earth's surface. The most common purpose of quarries is to extract stone for building materials. Quarries have been used for thousands of years. Quarrying material for use in building materials was much more work. Stones had to be carried or dragged out of quarries manually. Stones could also be hauled with pulley systems involving ropes and moveable wooden tracks or sleds. This process often involved thousands of slaves and other workers.

HARRIETVILLE CHINESE MINING VILLAGE: WHAT WERE THE PURPOSES OF THE STONE SLABS? In Season 4 we focussed on continuing the excavation of one building site, Hut WC1. Scattered across WC1 are a number of stone slabs, including a few examples as large as 500mm to 600mm. Some of these were found on the surface when WC1 was initially surveyed, while others were sub-surface and uncovered in the course of excavation in Seasons 1, 2 and 4. The stones occur both within and beyond the postulated interior of the building, positioned horizontally, and occasionally in small localised groupings, that might be viewed as meaningful. External to the building, the stones could possibly indicate pathways or yard surfaces around the sides of the structure, while those stones lying within the footprint of the building may signify the remnants of floor pavers, or stone pads to support elements of a timber floor. Many of the stones also lie at a shallow depth, not much deeper than the overlying topsoil, and as such their deposition could post-date the abandonment of the building. It is probable that the significance of these flat stones and their relationship to the building, externally and internally, will only be established following extensive excavations across the whole of WC1, resulting in the discovery of other stone groupings that can be jointly assessed. Join us for Season 5 in Nov-Dec 2024, as we continue to explore the Harrietville Chinese Mining Village.

14th June 2024 (I request you to read my complete post) 1st half Mission "Manganetize Bajaur" Me, Engr. Muhammad Saqib Jan n Engr Furqan Khan participated in this survey as the team of KJMEC. Please read my comment for detail. 2nd half of the day Mission Invasion - Monstrous Mohmand Marble Clusters 1- In my previous posts I have already exclaimed Mohmand marble clusters as "the monster". Few of the many reasons are: There are multiple clusters of marble resources in Mohmand. These are "Ziarat", "Khanqaah", "Baidmini", "Peepal", "Yarakhel", "Mallagori", "Spinkai" etc. I visited Baidmini cluster. 2- Each cluster has massive "marblous" mountains with the potential of incorporating hundreds of small-scale mining projects each. Here small scale means the working width of 35 to 50 m only. However, by and large each of such small projects may yield 5,000+ tons monthly production. 3- There may be multiple clusters of marble in Buner - KP but massiveness, the quality and the quantity of Mohmand clusters are beyond competition. Ziarat and Khanqaah clusters have collectively been mined out since last 18 years but the excavation appears to be as small as just "a visible hole" in the mountain. 4- Mohmand has nearly a dozen commercial variants of white to grey marbles with established trust on the quality of these stones. 5- I have a myth (because I don't have any evident resource estimation at the moment) that if there operates 1,000 mines simultaneously in Mohmand clusters, each producing average 5,000 tons monthly production, then marble resources of Mohmand clusters may last for 100 years or may be more. Mark my words I may not be too illogical in my analytical thinking!!! 6- Mohmand clusters have the commercial variant named "Ziarat (super) white marble" which may be considered as among the best (if not the best) marbles across the globe. Mark my words!!! 7- More importantly, Mohmand clusters are compatible for mechanized mining as well as conventional techniques of "drill and blast". I believe there is a good room here for transformation from being conventional to being mechanized and "it's never too late until it's over"!!! 8- One secret or let me exclaim it an "open secret". There are areas of Ziarat white marble in Mohmand clusters where in my opinion, few of the world's largest marble quarrying projects may be initiated. In terms of spread and production!!!! Mark my words!!!! 9- Treasure or Trouble!!! I rank Mohmand marble clusters as "The Treasure" rather than "The Trouble" but for me it's not what and how much you have, it's more about what your vision and execution plan. 10- There is a very encouraging potential of establishing "Processing Factory Clusters" here in Mohmand district. I will propose a few of my perceptions about contingent policies in the next posts insha Allah. Please stay tuned. Finally I want to salute all stakeholders associated with the mining, transportation and processing projects of Mohmand Marble Clusters.

This is a living picture of 80–90% of coloured stone extraction process globally. Mostly informal and carried out mainly in remote locations by locals, foreigners, and neighbouring "guests" amongst others. It also paints a vivid depiction of the hard work and dedication that goes into extracting and sourcing these valuable resources.   Despite the challenges faced by artisanal miners, the coloured stone industry remains a vital part of the global economy, bringing beauty and value to consumers around the world, including the vibrant hues of the gems now coming out of these pits! As technology advances and consumer demand grows, the coloured stone mining industry must adapt and innovate to meet the needs of a changing world while maintaining a commitment to responsible practices and sustainable development.

WHAT KINDS OF GOLD ORE? Placer gold When you’re panning for loose gold in gravel and sand, you’re looking for placer gold. Placer gold is already separated from the rock it formed in and can look like flakes, powder, or nuggets. For flakes and powder it’s best to assay the gold with an acid or heat test. Gold nuggets, however, will look like rounded yellow stones. Lode gold This is the gold that is still in the rock. Lode gold is found in quartz veins, with other precious metals in igneous and metamorphic rocks, and with iron ore in sedimentary rocks. There are several types of lode gold ore:[15] · Quartz gold ore is found in large veins of quartz, most commonly rose quartz and rainbow quartz. If the gold is on the surface of the rock it’ll look like shiny yellow flecks or veins of gold.[16] · Iron oxide copper gold ore is found on the edges of granite or as long bands of dark rock flecked with gold.[17] · Sulfide gold ores will be filled with shiny flecks, but not all of them will be gold. Gold and fool’s gold can form alongside each other, making this kind of ore deceptively chock full of shiny material.[18] · Blue clay gold ore is found in, you guessed it, blue clay. It will be mixed up with black sand and tiny pieces of quartz.[19] · Granite gold ore looks like flecks of gold in the dark parts of granite.[20] Sources: 15: https://lnkd.in/ge3ePQkq 16: https://lnkd.in/g__Vezs7 17,19,20: https://lnkd.in/gRgQQBaW 18: https://lnkd.in/gW4EHHKZ Attention to all geologist, exploration professional and those who interested in Gold, do come join us in our upcoming online workshop course Gold Exploration from Scratch!

15th and 16th August Trans-Basham Chromite and Granite Assessments - Alpuri and Duber areas. Gneiss time In this video I am briefly telling about the piece of stone detached from Gneiss rock. Gneiss is a metamorphic rock (may be of igneous or sedimentary origin). Frequently observed in northern areas and Azad Jammu Kashmir (Pakistan) igneous-origin gneiss rocks have been proving to be integral and extremely appealing dimension stones. Gneiss is generally commercially titled as Juparana (granite). In Pakistan Calsery Juparana (AJK), Golden Juparana (Lower Dir), Pink Juparana (Lower Dir), Grey Juparana (Lower Dir), Pink Cobra granite (Shangla), Purple Cobra (by and large every mountain of Sawat), Cosmo-wave granite (Bajaur) are few of the examples of commercially available gneiss rocks. Duber nala ( Lower Kohistan ) has detachments of multiple varieties of unexplored prospects of Juparana (Gneiss) deposits upstream. We aimed to visit the remotely located chromite area but we didn't have any anticipation about the remoteness. After reaching Duber we were told at sudden that the tracking time may be around three hours while after three hours tracking we knew that we are still three hours away from our destined area. Due to my busy schedule and upcoming back to back commitments, I request to delay the visit for ten days to two weeks or till the next schedule.
