Xanadu Mines' share price soared more than 50 per cent today after the company received an 8 cents per share takeover offer from unlisted Bastion Mining, valuing the Mongolian-focused copper-gold developer at $160 million. The offer follows hot on the heels of an expired exclusivity period earlier this month over a control transaction the company was negotiating with joint venture partner and major shareholder Zijin Mining.

In a major shift for Mongolia's Kharmagtai copper-gold project, Xanadu Mines has let its exclusivity deal with mining giant and JV partner Zijin lapse after failing to reach a control deal. Despite a promising proposal in April, Zijin could not commit within the tight timeframe. Xanadu will now pursue shareholder approval to trigger its 25% put option and reopen the door to other suitors, while continuing discussions with Zijin.

In a dramatic plot twist, Xanadu Mines has indefinitely postponed a shareholder meeting to approve a 25 per cent sell-down of its massive 4.7- million-tonne copper and 11-million-gold-ounce Kharmagtai project in Mongolia to Zijin Mining. The company says the delay will allow both parties to discuss a range of potential corporate outcomes. The big question is: What's brewing behind the scenes?

Xanadu Mines has handed over the reins of its flagship Kharmagtai copper-gold project in Mongolia, following the successful transition of operatorship to its joint venture partner, Chinese mining giant Zijin Mining. Zijin will now progress the world-class Kharmagtai project towards final development, following a promising prefeasibility study delivered by Xanadu late last year.

Xanadu Mines has unveiled a prefeasibility study of biblical proportions at its Kharmagtai copper-gold project in Mongolia's South Gobi Desert, including a pre-tax US$1.4 billion NPV, an IRR of 31 per cent at spot commodity prices and a mine life of nearly three decades. The study confirms the project's potential as a globally-significant, low-cost, long-life mining operation.

Xanadu Mines has confirmed it is in the final stages of completing a prefeasibility study on its Kharmagtai copper-gold project that sits in Mongolia's South Gobi region. The company recently handpassed operational duties for the massive project to joint venture partner and Chinese behemoth, Zijin Mining, and says it has taken additional time to finalise the mine design to ensure a higher standard.

Metallurgical testwork at Xanadu Mines' Kharmagtai copper-gold project in Mongolia has highlighted impressive recovery levels of 80 per cent from sulphide feed and a high-grade concentrate with low impurities. The potentially-saleable concentrate shows grades of up to 25 per cent copper and 25 grams per tonne gold from the porphyry deposits at the company's South Gobi site in the landlocked East Asian country.

Xanadu Mines has revealed a significant increase in the mineral resource estimate for its flagship Kharmagtai copper-gold project in Mongolia, reporting a 463,000-tonne increase in contained copper and a 746,000-ounce rise in contained gold. The boost has been driven by both the results of new drilling at the White Hill deposit and a refined pit design generated as part of the company's current prefeasibility studies.

Xanadu Mines has hit paydirt with results from its most recent drilling at the Kharmagtai project in Mongolia it shares with China's Zijin Mining Group. The company says it has expanded the new, higher-grade copper-gold mineralised zone at its White Hill deposit and doubled the mineral resource grade at its Golden Eagle prospect – and now believes it may be onto a significant copper-gold system.

Xanadu Mines has entered into a binding term sheet to earn up to 80 per cent of the Sant Tolgoi project in Mongolia which hosts multiple shallow copper-nickel targets over several kilometres of strike. The deal adds to the company's already significant presence in Mongolia which is home to its flagship Kharmagtai copper-gold project and its highly prospective Red Mountain operation.

Xanadu Mines has revealed its massive Mongolian copper-gold Kharmagtai deposit is now connected to the local electric grid, paving the way for current and future construction and exploration activities. The company says its vital 35,000-volt connection to the Mongolian Southern Electricity Distribution Network is expandable and will accommodate Kharmagtai moving closer towards operational mine status.

Xanadu Mines has wrapped up the next two phases of its strategic partnership with Chinese copper goliath Zijin Mining, giving it access to funding for the exploration and evaluation of its Kharmagtai copper-gold project all the way up to a decision to mine. The deal will see US$35 million invested directly into the project and a 50-50 joint venture created between the parties.

Sihayo Gold says transitional and fresh material from a zone beneath its proposed Sihayo-1 pit in North Sumatra, Indonesia could be economically mined following a recent uplift in metallurgical recoveries. The company recently announced its high-pH caustic pre-leaching process could recover over 80 per cent of the site's gold and now plans on testing samples from a seven-hole, 2216m campaign to confirm its theory.

Indonesia-focused gold explorer Sihayo Gold has tabled a maiden resource for the company's Sihorbo South deposit within its Hutabargot Julu project and in the process piled on another 100,000 ounces of gold to its 1.56-million-ounce base. The explorer plans to conduct a scoping study to assess the potential to include the new resource as a satellite operation for its flagship project.

Xanadu Mines is kicking off a new exploration campaign at the company's highly prospective Red Mountain project in the South Gobi region of Mongolia targeting shallow high-grade gold, silver and copper. A previous diamond and RC drill program at the site uncovered some impressive results at the site's Bavuu and Diorite deposits with a number of hits from surface.

Xanadu Mines has received Australian Foreign Investment Review Board approval for Chinese mining giant Zijin to acquire shares in the company to develop its Kharmagtai copper-gold project in Mongolia. It is the first of three approvals required for Zijin to continue its three-phase investment in Xanadu that was announced in April. The project has a mineral resource estimate of 1.1b tonnes for three million tonnes of contained copper and eight million ounces of gold.

Indonesia-focused explorer Sihayo Gold has followed up its recent high- grade surface samples with strong diamond drilling assays from a 30-hole exploration program that has extended its Sihorbo South target and firmed up the modelling for its maiden mineral resource estimate. Sihorbo South is now shaping up as a satellite operation to the company's main Sihayo Starter project.

Indonesia-based gold explorer Sihayo Gold has increased its initial expected gold recovery rate from 35 per cent to a solid 80 per cent in fresh rock samples after trialling high pH leaching metallurgical test work on ore from its advanced Sihayo gold project in North Sumatra. Transitional ore samples also received a healthy boost to the recovery rate, rising from 52.3 to 74.5 per cent.

Indonesian-focused explorer, Sihayo Gold is off to a flyer from regional exploration drilling at its Sihorbo South epithermal vein gold and silver prospect on the island of North Sumatra. Results from the first three holes sunk into the prospect have returned bumper grade gold and silver, including a tasty one metre strike going 198 grams per tonne gold from 89m.

Indonesian-focused explorer, Sihayo Gold has delivered more solid gold hits from regional exploration drilling at its namesake project in North Sumatra. New hits at its Hutabargot Julu target area include 10.2m at 2.5 g/t gold from 153m at the Penatapan epithermal vein gold and silver prospect. The company is seeking to unearth more ounces to add to an already impressive 1.5-million-ounce gold resource base.

Sihayo Gold has produced encouraging metallurgical test work results that point to a potential increase in the all-important gold recovery rates at its developing namesake Sihayo “starter” gold project in North Sumatra in Indonesia. The company says average recoveries in its latest test work show an improvement of up to 25 per cent via the use of caustic pre-leaching on various refractory ore types from the project.

Aspiring Indonesian gold producer Sihayo Gold has been making solid progress on the ground at its developing Sihayo “starter” gold project in North Sumatra which is getting tantalisingly close to being “shovel ready”.
