Yarara Gold project So while the stock market gets it's head around the sp I'm doing some leg work and it's Amazing how much just a little research can do , check out the 90g/tonne assays on the bottom right corner. That was never mentioned in the ANN.That's one of the dormant mines on the tenement ,Perseverance. Average grade 45g/t past production. In 1907 they dewatered the main shaft and got assays of up to 90g/t GOLD. TheYarara reefs follow prominent structural trend, this can be interpreted as afault zone.
The Rangatira mine, 60g/t, that's actual mined grades not drilling grades. It's on thesame fault zonethis can be interpreted as afault zone.
And let's all welcomeJust-In-Time, 30g/t producing over 20,000 oz of Gold historically. Again its on thesame structural trendthis can be interpreted as afault zone. You will notice a discrepancy in the amount produced between the value ($7920) and the box marked with X below (10,000-1,000,000) . That's because they were transporting a significant amount of ore to Victoria for treatment . Check the second attachment in the total production boxBillabong.
Has anyone noticed the 335 degrees on all three tenements in notes at the bottom right hand corner? ( The Yarara reefs follow prominent structural trend , this can be interpreted as a fault zone ). All three mines Perseverance, Rangarita and Just-in-time.
Now look at the Yarara Gold project map. Look at the direction of all twenty mines and then look at the concentration of the three mines Perseverance, Rangarita and Just-in-time in the middle. 45g/t, 60g/t and 30g/t all proven in past production . All these mines follow prominent structural trend ie same fault zone
Has anyone seen this high concentrated area of high grade GOLD anywhere ? Mind you this is proven from actual past producing mines. Add to that it's on the Lachlan Fold Belt. I know where Mr Greenaway will be starting his exploration and will have further potential exploration SE and NW.These tenements are GOLD. GLTAH
A FEW Other GOLD MINES ON LEASE Initially when I started searching about the Yarara Gold Project , Information was scarce. That's because there was very little exploration done plus they were separate tenements and held different names like Ournie, Jingellic, Rangatira , Billabong Rosewood, Lankeys Creek, Isabella Reef , Peep-O-Day reef etc etc They were joined together under one claim later as is it stands now. Now that I got my head around it and worked out the previous holders of the tenements , there is actually a lot more info. I'm just sifting through them at the moment, great info and very very encouraging. For example , in one grab sample there was 15oz/t (459g/t)!!!!
Also very important finds were the reasons for stopping production early days (eg. world war II, low gold price), relinquishment of the license (eg. uncertainty of the effect of Mabo in 1990's and company shifted all attention to Namibia Africa and changed name of Company to Namibian Copper Limited) , and/or sale of the tenements (eg. Endeavour Minerals Pty Ltd). These tenements are oozing GOLD.
EXPLORATION LICENCE 7732 RANGITIRA PROJECT JINGELLIC NSW 1 st ANNUAL REPORT TO to 5 th May 2012 REPORT BY DAVID TIMMS
SUMMARY The EL7732 Rangitira tenement lies along an inherent suture that locally is known as the Yarrara Shear Zone that Hosts the Yarrara Goldfield consisting of a series of predominantly gold based mineral occurrences over a strike length of about fifty kilometres. The Yarrara Goldfield occurs within Middle to Late Ordovician metasediments of the Wagga Group in the northern portion of the Yarrara Shear Zone whereas the southern portion of the Shear Zone predominantly occurs within intruded fractionated S-type granitic rocks largely of the Early Silurian Koetong Supersuite. The northern portion of the Yarrara Goldfield deposits within the metasediments generally appear to occur within narrow east-west striking quartz veins which are postulated to be the result of tensional dilations along joint planes caused by movement within the Yarrara Shear Zone. Chloritic alteration is commonly developed in the host rocks adjacent to the veins with minor arsenopyrite and pyrite associations.Historical reports indicate that there were no extraction problems associated with refractory sulphides. The southern portionof the Yarrara Goldfield deposits occurring within thegranites are predominantly narrow quartz veins containing gold. Gold mineralisation in this area is also contained within narrow quartz veins (50mm to 600mm) but the vein orientations are variable, both with individual veins and between veins. The mineral occurrences were mostly identified and worked on by prospectors- cum miners in the late 1800s and early 1900s. The main gold deposits that were mined in the northern portion were the Billabong Gold mine, in the extreme north of the tenement and closest to the town of Holbrook, the Rangatira Mine, Just in Time mine and the Perseverance Mine plus the Four Mile Creek, Mountaineer and Unnamed as indicated in Table 1 below: Table 1Early Mining Northern Yarrara Goldfield Mine Max Workings Depth Production dates Average Grade (Au) Output (oz.

However records of their [production were limited by when the New South Wales Mines Department began recording the production figures from 1875. The combined production of the two reefs would appear to be in the order of seven thousand ounces of gold with no mention of silver for an average grade of around forty eight grams per tonne. Both ore zones are characterised by greisenitic wallrock alteration with abundant pyrite and arsenopyrite with minor copper, silver lead and zinc mineralisation. In those days it was not worth mining and crushing the lower grade mineralisation in the altered wallrock associated the gold reefs.However, these days with the gold price hovering around $1600 per ounce it is well worthwhile sampling the wallrocks surrounding those old gold reefs especially as they are still close to surface and easily mineable and the gold now more easily extractable. The Peep-O-Day Reef extends for a strike length of approximately 1200 metres and the Isabella reef approximately 1,000 metres. Other gold mines were the Minchins Gold Show, the Horse Creek gold veins , the Lankey’s Creek or Musgrave O. In addition to the gold reefs there are other mineral occurrences particularly in the southern part of the tenement: The Carboona Mineralisation was mined by BHP from 1918 to 1925 for fluorite with by- product lead and silver The Musgrave tin tungsten lodes and associated alluvials were mined between1901 and 1929 (probably at high cut-off grades). The Horse Creek tin lodes were worked intermittently between1873 and1890. In conclusion there are a great number of immediate targets associated with the old workings that have demonstrated to be mineralised with gold and possibly other associated metals such as silver (lead, zinc and tin and tungsten) that deserve to be followed up with detailed modern exploration techniques including soil geochemistry (assaying now down to parts per trillion), magnetics ,gravity and Induced polarisation together a sophisticated array of downhole geophysical probes measuring many different physical properties. The main targets will be to find wider widths of lower grade gold in the wallrocks of the gold reefs together with high grade gold in extensions along strike and at depth. EL 7732 –RANGITIRA PROJECT MAY 2012 5 Figure 1. EL7732 Rangitira Project Location Map. EL 7732 –RANGITIRA PROJECT MAY 2012 6 Historical mining occurred in the late 1880s and early 1900's and relatively little exploration has occurred since.
Now read the potential for bulk grade deposits potential just like Cadia and North Parkes, and remember we are on the Lachlan Fold Belt with similar geology to them.
7. EXPLORATION POTENTIAL Twenty or more old mines and prospects occur over a curvilinear zone over 50km in length in the Rangatira area. Many of the areas have been investigated individually but the zone has not been investigated as a single entity. A complete review of the entire zone is warranted to evaluate the potential for this type of mineralisation, particularly in terms of theoccurrence of one or more bulk low grade deposits.now remember how I refered to the de-watering of the mines and assays of 90g/t came back? have a look at this :
The deeper mines were worked to recorded depths of around 40m at Rangatira and 65m at Perseverance. The mines were wet,with records showing that Rangatira required larger pumps than were initially available. Recovered grades were variable, with some crushings giving grades varying from 11 pennyweights per ton(16.5g/t) up to 15oz/t (459g/t). In part this may have been extraction difficulties, as the gold was noted to be very fine in places, although visible gold is also noted in the records.
POSSIBLE SILVER AND ZINC, BHP EXPLORATION ON PART OF TENEMENT
Yep, no shortage of choice mate, GOLD/LITHIUM/COPPER/HALLOYSITE and you may even addSILVER at 124g/t and Zinc at 1.35%. Drilling done byBHPpre 1935. Personally I'm happy with two projects free carried(Lithium and Copper). Better we concentrate on GOLD first n Halloysite second because we are sitting on a shit load of gold.
Mineralisation Gold mineralisation at the Yarrara Reefs mines is predominantly hosted within sediments and is postulated to have resulted from the movement of gold-bearing a b fluids along major north west trending faults such as the Yarrara Shear. Gold-bearing quartz veins within the sediments generally have a chloritic alteration assemblage within the host rock, with minor arsenopyrite and pyrite associations. Historical reports note no extraction problems associated with refractory sulphides. Gold mineralisation is associated with narrow quartz veins that strike east west and are contained within the larger north west trending fault. These minor, mineralised, east-west faults are postulated to represent tensional dilations along joint planes. The Yarrara Shear which contains the Yarrara Reefs mines, hosts further gold mineralisation to the north and south along strike outside the project tenure. The Billabong gold mine to the north and the Carboona lead-zinc-silver-fluorite mine south of Yarrara are situated within the Yarrara Shear Zone. Carboona is a precious and base metals mine located 15 kilometres south of the Yarrara Reefs on a cross fault with the Yarrara Shear Zone. A resource estimate prepared byBHPLimited from underground diamond drilling is stated at 35,000 tonnes at 34% Calcium Fluoride (CaF2), 10% lead (Pb),1.35% zinc (Zn) and 124 g/t Silver (Ag).
