Peter Akerley, a founding father of Erdene Useful resource Improvement Corp., first turned conscious of Mongolia’s mineral riches within the mid-Nineties as exploration supervisor for one of many largest western financed programmes within the nation. As a geologist, with 35-years of expertise, he describes himself as being “awed” by the nation’s geological potential (‘Erdene’ is the Mongolian phrase for treasure, or jewel).
Akerley led a gaggle of explorers and financiers to determine Erdene as a personal entity focussed on Mongolia gold and copper exploration in 2001. The Nova Scotia-based firm listed on the TSX-V in 2004 and graduated to the principle board of the TSX in 2005. In 2018, Erdene cross-listed on the Mongolian Inventory Trade, the place it stays the one agency listed on each exchanges.
Following a country-wide analysis in the course of the firm’s preliminary years, Erdene acquired Gallant Minerals from Mohamed Al Fayed (the well-known former proprietor of Harrods in London), which held the Zuun Mod copper-molybdenum prospect in 2005, bringing the corporate to the Khundii Gold District. From 2007 to 2011, Erdene explored and outlined Zuun Mod as one in all Asia’s largest undeveloped molybdenum-copper porphyry deposits. Latest value will increase in molybdenum and copper have elevated the worth and curiosity on this venture, however the firm is now largely focussed on the gold district it has found, 35km to the west.
Following the porphyry discovery at Zuun Mod, in 2008 Erdene turned its focus to the Late Paleozoic Island Arcs in southwest Mongolia. Of explicit enchantment has been the Late Carboniferous mineralisation within the Edren Terrane (310-335ma; now generally known as the Trans Altai Terrane). Erdene was the primary firm to undertake methodical exploration of the extremely potential portion of the Central Asia Orogenic Belt (CAOB), which is host to a few of the world’s largest gold and copper-gold deposits, anchored by the Muruntau deposit within the west and Oyu Tolgoi within the east.
Erdene’s regional exploration produced the most important geological database of the Mongolian portion of the CAOB, and led to the identification of the Altan Nar polymetallic deposit in 2011 and the Bayan Khundii deposit in 2015. Collectively, these deposits, and a large number of different prospects, kind the 170km2 Khundii District associated to shallow subduction Paleozoic intrusive occasions inside a 40km by 20km space.
Erdene has the sturdy backing of Canadian billionaire Eric Sprott, who turned the corporate’s largest shareholder (with 11%) in August 2020 following a C$15 million funding (just lately elevated to 14% by market purchases). Shortly after the 2020 financing, the European Financial institution for Reconstruction and Improvement, one of many largest international direct buyers within the nation, with over €2 billion deployed in Mongolia to this point, gained a major curiosity, and presently holds a ten% fairness curiosity following a mortgage conversion. Latest financing has included an over-subscribed providing in Mongolia to boost US$5 million, and the execution of a mandate letter by Export Improvement Canada for a US$55 million senior debt facility that’s anticipated to be the cornerstone of venture finance for Bayan Khundii.
Erdene acquired a Mongolian Tax Stabilisation Certificates for Bayan Khundii in December 2021. Moreover, the corporate has acquired most of the permits to start building of the venture.
Ongoing Exploration
Erdene expects to achieve a complete gold useful resource of over 2 Moz within the Khundii District by the tip of 2022. The corporate’s attentions are centred on the thrilling Bayan Khundii venture (which means ‘wealthy valley’; see beneath). Along with Bayan Khundii and the deposit at Altan Nar (which means ‘golden solar’), situated roughly 16km north, Erdene is investigating a number of different prospects, together with following up on the 2021 discoveries at Darkish Horse Mane and Ulaan. The primary section of the 2022 programme will embody 10,000m of diamond and three,000m of rotary air blast drilling.

The corporate’s gold useful resource (NI43-101) already quantities to 1.1Moz, and along with increasing its present prospects, Akerley is assured of additional grass roots discoveries. Erdene, he says, is focussed on constructing a portfolio of gold prospects with multi-million-ounce potential. Akerley notes “The rationale we got here to Mongolia within the first place is that potential for giant-sized, tier-one deposits, and that is what’s starting to unfold within the Khundii district”.
Akerley, who has held the place of President and CEO since March 2003, describes final season’s exploration as “an incredible success”. He notes that, in 2021, “very excessive grade, close to floor, oxide gold mineralisation was found at Darkish Horse, and exceptionally thick intervals of gold mineralisation enveloping high-grade zones had been intersected on the Ulaan Southeast discovery.” These prospects are all a part of the identical intrusive associated mineralising occasion as at Bayan Khundii.
Concentrate on Bayan Khundii
A bankable feasibility research on this prospect in mid-2020 outlined an open-pit operation to extract round 63,500 ozy from high-grade ore (of better than 3 g/t Au) with a six-year mine life). Greater grade materials at Darkish Horse, 2.4km north, in addition to mineralisation intersected on the Ulaan Southeast, are being evaluated for the potential to allow manufacturing to achieve 80,000 ozy utilising the mill’s extra capability (with minor modifications).
Within the 2020 feasibility research, ore reserves are given as 1.2Mt of confirmed materials (grading 4.2 g/t) and a pair of.2Mt of possible materials (3.5 g/t), containing a complete of 409,000oz (grading a mean of three.7 g/t). The operation has an anticipated all-in sustaining price of US$733/oz. The feasibility research prompt a capital expenditure of US$59 million, giving an inner charge of return of 42%, payback inside two years and web current worth (at 5% low cost charge) of US$100 million (utilizing US$1,400/ozgold). The free money from gold manufacturing at Bayan Khundii (an annual US$40 million within the feasibility research) could be employed to help anti-dilutive exploration of the district.

A Detailed Environmental Impression Evaluation has already been permitted by the Ministry of Atmosphere and Tourism, and a neighborhood co-operation settlement signed with the provincial authorities. Design work is accomplished, and lengthy lead-time gear such because the comminution circuit has been ordered.
Though the “stage is ready” for a building determination and a few early works have commenced, Erdene’s administration will take various components into consideration previous to the graduation of full building. Most significantly, the exploration successes generated in the course of the Covid-19 improvement slowdown have offered a chance for a better quantity operation. As well as, the anticipated dangers of transport delays associated to the pandemic (particularly on the China border), quickly rising prices and provide chain uncertainty shall be assessed in regard to establishing a begin date and anticipated first gold pour (18 months after the development graduation).
Different Prospects
Altan Nar: This carbonate base steel intermediate sulphidation prospect is just like a few of the world’s largest deposits, comparable to Fruta del Norte and Rosia Montanna. Situated 16km north-west of Bayan Khundii (on an all-season highway), Altan Nar has an indicated gold-silver-lead-zinc useful resource containing 318,000oz of gold, and an inferred useful resource containing 186,000oz (each at 1.9 g/t).
Ulaan: Found in July 2021, this sediment is simply 300m west of the Bayan Khundii deposit. Comply with-up drilling has already confirmed thick sequences of high-grade mineralisation. The mineralisation at Ulaan Southeast seems according to Bayan Khundii.
Darkish Horse Mane: This gold discovery (in January 2021) lies 2.4km north of Bayan Khundii, and contains numerous high-grade zones.
Zuun Mod: That is believed to be the most important undeveloped molybdenum-copper venture in Asia, with a measured and indicated useful resource containing 274Mlb molybdenum and 331Mlb copper. There’s a additional inferred useful resource containing 158Mlb of molybdenum and 198Mlb copper. Erdene just lately initiated a strategic evaluation of the Zuun Mod asset, confirming the venture’s potential worth.
