8245L & Alpha = Mugloto = Top $
1. Demand for medium to higher quality ruby is very strong according to Gemfields June'17 Auction report (requested by clients)
2. Unprecedented demand from China according to Fosun group
3. Mustang's strategy
* generate significant revenue = mine secondary deposits only

Key word: Mugloto
The main bulk sampling pit in the Mugloto area is the most productive pit by value.
Top-grade ruby rough ($600+/ct) from Mugloto, Gemfields
Now, ruby rough from newly acquired tenement 8245L & Alpha, Mustang
I strongly believe that more than 50% rubies from 8245L & Alpha are medium to top quality rubies ($300~$600/ct)
Why ? Please keep reading..
From the research report 24 May 2017
Key word: Mugloto
So called secondary mineralisation at Gemfields’ Maninge Nice deposit is probably the insitu weathered primary mineralisation - the stones at Maninge Nice are reportedly largely of “commercial” and not gem quality.
Secondary mineralisation at Mugloto, although of significantly lower grade, is of much higher quality, with the rubies being of a darker colour, less included and fractured (a large proportion of the Maninge Nice stones are pink sapphires) – this indicates a different primary source for the rubies, and with our understanding being that these stones make up the bulk of Gemfields’ high quality auction parcels.
The mineralisation at Mugloto is hosted within a gravel bed, with pitting and auger sampling (as reported in the 2015 CPR) indicating thicknesses of between 0 and 1.5m, with an average thickness of 0.32m.
Grades from the trial/ bulk sampling pits at Mugloto ranged between 0.11ct/t and 5.64ct/t, with an average of 2.57ct/t – of this around 50% of the recovered stones were in the higher value ruby and high ruby classes.
The gravels are interpreted as being alluvial in origin, possibly being reworked by braided streams after a flood event – the interpreted gravels cover a significant proportion of Gemfields’ three northern licences – these are paleochannels, with rubies largely found in “trap” sites associated with coarser gravels, cobbles and boulders.
Like Mugloto, Alpha is a secondary deposit, with rubies hosted in a gravel bed with thicknesses of up to 3m, and averaging ~0.5m – the prospect is located along the contact of an intrusive with the metasediments.
Mustang has stated that the rubies collected as part of the current bulk sampling programme within tenement 4143L are of comparable quality to those at Mugloto – this has been supported by comments by Mr. Vincent Pardieu of the Gemological Institute of America (“GIA”) made on a site visit to the Montepuez area and as quoted, with his permission, by the Company:
–Mustang rubies “are of high quality with some gemstones showing variety of colour, size and clarity”.
–Work done to date by Mustang is “very encouraging and indicative of a secondary ruby deposit similar to some other deposits GIA has studied in the Montepuez area
Similar quality rubies are being collected by artisanal miners on the newly acquired tenement 8245L (Figure 4).
(CJ said 8245L could be even better than Alpha deposit at the RRS - this is being proven by latest announcement)

Primary vs secondary deposit
