Significant 107% Increase of Mineral Resource Ounces at Laverton Project. Magnetic Resources NL ASX:MAU, MD George Sakalidis “The Lady Julie North 4 Resource has been the prime drilling focus as reported in periodic releases to the ASX. It has multiple stacked lodes with a number of thick intersections that have not been closed off at depth. The initial deeper drilling started on the 25 January 2023 and has expanded in subsequent months to a 95-hole RC program for 16,356m. Drilling is continuing, with holes in excess of 400m depth, which is expected to increase the current resource at LJN4 of 13.1Mt at 2.02g/t for 852,000oz at a 0.5g/t cut off (Table 2). This LJN4 deposit sits within a regional structure called the Chatterbox Shear Zone that extends over a 12km length within the Magnetic tenements. This shear extends southwards of LJN4 and has had initial AC and RC drilling completed and some anomalous intersections that will be followed up with some shallow RC drilling for the purpose of finding further gold deposits. Drilling in the last 6 months included diamond drill holes for geotechnical evaluation of proposed pits, and for hydrology analysis. Project environmental, heritage and technical background studies are close to completion – optimisation and pit design has commenced on LJC and the expanded LJN4 – the aim is to prepare and submit a Mining Proposal in early 2024. Other strategic opportunities are also being investigated”.

Variscan Mines (ASX:VAR) is pleased to report further high-grade zinc intercepts from the ongoing underground diamond drilling program at the San Jose Mine, near Novales, located in Cantabria, northern Spain. Highlights include: • More strong assay results received from current underground infill and extensional drilling campaign at the San Jose Mine • Significant drilling results include:   o NDDT033 14.10 m @ 5.31% Zn, 0.44% Pb   o NDDT032 11.00 m @ 6.66% Zn, 0.72% Pb   o NDDT034 4.65 m @ 5.49% Zn, 0.14% Pb   o NDDT035 4.00 m @ 5.92% Zn, 0.26% Pb • Results indicate significant mineralisation intersected outside the existing Mineral Resource Estimate model delivering growth potential • Drilling successfully tested new structural targets defined from recently completed structural geology study • Upscaled underground drilling will continue targeting previously untested south west extensions of San Jose Mine and into the Udias Mine complex • All new drilling results are to be incorporated into the Mineral Resource Estimate update planned later in CY2024 To learn more please read the full ASX announcement: https://lnkd.in/gMUSYMmH

One of the great frustrations in the junior resource sector is that even when you have prospective drill targets and the money to drill, you often have to wait for permits and weather before you can actually drill. Bayhorse Silver $BHS is facing this with its newly acquired Idaho property on the Izee/Olds Ferry suture. It has three low resistivity targets it wants to drill, but even in mining friendly Idaho, permits will take at least a couple of months. The good news is that the company had already planned exploratory drilling from its underground drilling station in the Bayhorse Mine on the Oregon side of the Snake River. Now it is adding a low resistivity target its VTEM survey discovered at the Western end of its workings. The drill is already turning, no permit needed. What this means is that $BHS should have results to report in the next few weeks while it waits for its Idaho permits and the end of Winter. https://lnkd.in/dgrcD-Eg

𝐑𝐞𝐝𝐮𝐜𝐢𝐧𝐠 𝐅𝐥𝐲𝐫𝐨𝐜𝐤 𝐈𝐧𝐜𝐢𝐝𝐞𝐧𝐭𝐬 𝐢𝐧 𝐌𝐢𝐧𝐞 𝐁𝐥𝐚𝐬𝐭𝐢𝐧𝐠 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧𝐬 Mining operations are inherently hazardous, with various risks that can lead to severe accidents. One such risk is flyrock during blasting operations. Flyrock refers to rock fragments that are propelled beyond the designated blast area, posing significant dangers to personnel, equipment, and the surrounding environment. Ensuring safety in mining operations necessitates reducing flyrock incidents through meticulous planning, advanced techniques, and stringent safety measures.
