Casa Update; further significant gold mineralisation at Akyanga


Since announcing the acquisition of Casa Mining Limited ("Casa") in November 2017, the management of Ortac has been actively working to complete the acquisition and integration of Casa.  To date Ortac owns 87.4% of Casa and expects the acquisition to be completed shortly.  As part of the integration with Casa, Ortac management have completed a number of meetings as well as an extensive site visit - in this regard Ortac has also been completing a review of historical drilling data at Casa which includes over 100 holes of exploration drilling predominantly at the Akyanga license area (which has a JORC Mineral Resource of 1.5m ounces @1.65 g/t Au) ("Akyanga").  The results of these will be announced within the next month. 

In the meantime, Ortac is pleased to report further significant new gold assay results taken from the expansion and infill drill programme currently underway at Akyanga.


Highlights of the latest batch of drill results are as follows:




·     4.55m @ 3.15 g/t Au from 189.45m

·     6.70m @ 2.01 g/t Au from 209.80m




·     5.85m @ 2.47 g/t Au from 199.40m

·     7.80m @ 2.67 g/t Au from 240.70m; incl. 1.70m @ 10.46 g/t Au from 240.70m


Nick von Schirnding, Ortac's Executive Chairman, commented:

"With over 3,300 meters drilled in 2017, these are again a pleasing set of results, this time from the outer perimeter of our drilling programme at Akyanga - with good consistency of grade well above 2 g/t Au. Both 117 and 118 show good zones of mineable thickness and previous drilling results within 100 metres of hole 118 show 18 metres of 4.63 g/t. We are now evaluating the possibility of expanding certain conceptualised pits - with all the economic advantages that scale brings. We look forward to updating the market going forward as we continue work on this very exciting deposit."


Results of diamond core drilling


The results of these two diamond core holes for which assays have been received from SGS Laboratory Services in Mwanza, Tanzania are tabulated below.


The results are reported for mineralized intersections greater than 3 meters in length, greater than 0.5 g/t Au in grade and allowing for up to 3 meters of internal dilution.

Drill Results Summary


The latest drill holes MSDD0117 and MSDD0118 were drilled towards the outer perimeter of a conceptualised pit in a part of the deposit where there is a sparsity in drill data and correspondingly where the resource appears to taper off.


Diamond drill hole MSDD0117 was collared between existing and previously un-announced holes MSDD0083 and MSDD102. These holes are spaced approximately 200m apart and MSDD0117 successfully confirmed the continuity of the mineralisation between these two holes. Interesting intersections from these holes, include and are not limited to 2.29 g/t Au over 11.20m from 131.80m assayed from MSDD0083 and 5.59 g/t Au over 5.80m from 155.80m assayed from MSDD0102, which includes a high-grade interval of 15.17 g/t Au over 2.00m from 155.80m.



Diamond drill hole MSDD0118 was a re-drill of MSDD0116 which had to be abandoned at a depth of 85m. This hole was collared approximately 80m from existing and previously un-announced hole MSRC0002, which reported a highlight intersection of 4.63 g/t Au over 18m from 138m depth. MSDD0118 successfully extended the down dip continuity of the mineralisation reported in hole MSRC0002.


Quality Assurance/Quality Control (QA/QC)


The drilling was conducted using diamond core drilling with samples being collected at one metre intervals and half core sample of approximately 2-4kg was sent to SGS Laboratory Services in Mwanza, Tanzania. The sample was fully pulverized and analyses for gold using a 50g lead collection fire assay and an atomic absorption spectrometry finish to 0.01ppm Au detection limit. Full analytical QA/QC is achieved using a suite of certified standards, laboratory standards, field duplicates, repeats, blanks and grind-size analysis.


The spatial location of the samples is derived using GPS collar survey pickups and Reflex single shot downhole surveys taken every 40m down hole.

True widths have not been determined as the level of detail required to calculate accurate true widths is not yet available, as a result down hole widths have been reported instead. However true widths are not expected to differ significantly from the down hole widths reported.

About CASA


CASA is a private Mauritian registered company that is the 71.25 percent owner and operator of the Misisi Gold Project located in South Kivu, eastern DRC, approximately 350km south of Bukavu and 180km north of Kalemie.


The CASA licence area consists of three contiguous mining licenses (133km2), issued in March 2015 and valid for 30 years. These licenses encompass a 60km strike length of the Tanganyika graben within the Rusizian belt ("Misisi Corridor"), including the Akyanga Deposit along with the Lubitchako, Tulongwe, Kilombwe and Mutshobwe prospects.


The licences have benefited from considerable capital expenditure to date, including regional geophysical surveys completed in 2011, 19,522m of diamond drilling, 2,720m of reverse circulation drilling and excavated 6,274 line metres of trenches.


At CASA's most advanced project, the Akyanga Deposit, African Mining Consultants ("AMC") in June 2017 reported a mineral resource, within a US$1,250/oz gold selling price optimised pit shell, which defined a 1.05Moz JORC inferred resource @ 2.27 g/t Au (using a 1.5 g/t Au cut-off) within a lower grade envelope of 1.57Moz @ 1.65 g/t Au.




Au - the chemical symbol for gold.

g/t - grammes per tonne, the quantity of the element expressed as the number of grammes contained in one tonne of the host rock.

JORC Resource

Resource estimated according to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, as published by the Joint Ore Reserves Committee of The Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia.

Inferred Mineral Resource

 That part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill-holes which may be limited or of uncertain quality and reliability.

m - metre, a unit of length as per the International System of Units.

Mineralisation - the process or processes by which a mineral is introduced into a rock, resulting in a valuable or potentially valuable deposit.  It is a general term, incorporating various types; e.g., fissure filling, impregnation, and replacement.
