Orosur Mining Inc. ('Orosur' or the 'Company') (TSX:OMI)(AIM:OMI), is pleased to announce an update on the progress of Minera Anza's drilling campaign currently underway at the Company's Anza project in Colombia.
Results of further four holes.
Over 18,000m was drilled by Waymar Resources prior to it becoming part of Orosur in late 2014. Subsequent work by Orosur determined that much of this older drilling was oriented down dip, and while these holes often returned superficially attractive assay results, they did not provide sufficiently reliable geological information to fully understand the nature of the mineralisation and to allow accurate targeting and efficient expansion drilling.
As a result, much of the Company's initial 2,300m drill program currently underway, was designed to answer several outstanding orientation and structural questions and to provide insight into the style of mineralisation, with a focus on the potential for a hybrid polymetallic VMS/Epithermal model.
These four holes were drilled on three sections, and returned attractive gold intersections, assisted in addressing key structural questions, and returned wide intersections of high-grade Zinc that added weight to the polymetallic VMS model.
Both holes were drilled to assist in resolving a geological interpretation issue in the south of the APTA zone, that had resulted from earlier holes having been drilled toward the east or having stopped short of the mineralised zones.
Both holes were successful in resolving the questions posed, and both returned substantial intersections of high-grade gold and moderate zinc as reported.
Such zonation is expected and is an integral characteristic of Volcanogenic Massive Sulphide (VMS) deposits. However, given the orientation problems of previous drilling, this was the first hole to show this zonation so unequivocally and so provide tangible guidance for further targeting.
Mobilisation of 4th rig
The preliminary 2,300m drill program has now been largely completed and as planned, has addressed a number of outstanding geological questions. This has provided valuable guidance as to the nature and distribution of the mineralisation at APTA that will allow future drilling to be more efficiently targeted.
A decision has now been taken to move into the next phase of drilling with a 7,000m program and to that end, a 4th diamond drill is to be mobilised to site in coming days.
Orosur CEO Brad George commented: 'After much excellent work and several phases of drilling, it is pleasing to be at the point where we are now developing a greater understanding of APTA, its nature and genetic controls. It is also testament to the benefits of being in a JV with major companies that gives us access to a depth and breadth of experience and technical expertise that Orosur alone does not possess.
The emerging picture of APTA as a polymetallic, gold rich, VMS deposit is both an opportunity and a challenge - a challenge in having to now understand the zonation that is inherent in VMS deposits, but an opportunity in that the polymetallic nature (especially at high grades) is invariably a positive for project economics'

About Orosur Mining Inc.
Orosur Mining Inc. (TSX:OMI)(AIM: OMI) is a precious metals developer and explorer focused on identifying and advancing gold projects in South America. The Company operates in Colombia and Uruguay.
About the Anza Project
Anza is a gold exploration project, comprising three exploration licences, four exploration licence applications, and several small exploitation permits, totalling 207.5km2 in the prolific Mid-Cauca belt of Colombia.
The Anza Project is currently wholly owned by Orosur via its subsidiary, Minera Anza S.A.
The project is located 50km west of Medellin and is easily accessible by all-weather roads and boasts excellent infrastructure including water, power, communications and large exploration camp.
The Anza Project is subject to an Exploration Agreement with Venture Option dated September 7th, 2018, as announced on September 10th, 2018, (the 'Agreement') between Orosur's 100% subsidiary Minera Anza S.A ('Minera Anza') and Minera Monte Aguila SAS ('Monte Aguila'), a 50/50 joint venture between Newmont Corporation ('Newmont') (NYSE:NEM, TSX:NGT), and Agnico Eagle Mines Limited ('Agnico') (NYSE:AEM, TSX:AEM).
Samples are sent to the Medellin preparation facility of ALS Colombia Ltd, and then to the ISO 9001 certified ALS Global laboratory in Lima, Peru.
30 gram nominal weight samples are then subject to fire assay and AAS analysis for gold with gravimetric re-finish for overlimit assays of >10g/t. ICP-MS Ultra-Trace level multi-element four-acid digest analyses is also undertaken for such elements as silver, copper, lead and zinc, etc.
Gold intersections are reported using a lower cut off of 0.3g/t Au over 3m.
Forward Looking Statements
All statements, other than statements of historical fact, contained in this news release constitute 'forward looking statements' within the meaning of applicable securities laws, including but not limited to the 'safe harbour' provisions of the United States Private Securities Litigation Reform Act of 1995 and are based on expectations estimates and projections as of the date of this news release.
Forward-looking statements include, without limitation, the exploration plans in Colombia and the funding from Monte Aguila of those plans, Monte Aguila's decision to continue with the Exploration and Option agreement, the ability for Loryser to continue and finalize with the remediation in Uruguay, the ability to implement the Creditors' Agreement successfully as well as continuation of the business of the Company as a going concern and other events or conditions that may occur in the future. The Company's continuance as a going concern is dependent upon its ability to obtain adequate financing, to reach profitable levels of operations and to reach a satisfactory implementation of the Creditor's Agreement in Uruguay. These material uncertainties may cast significant doubt upon the Company's ability to realize its assets and discharge its liabilities in the normal course of business and accordingly the appropriateness of the use of accounting principles applicable to a going concern.
