Four Significant Regional Mineralised Trends Outlined from VTEM Airborne Survey to be Prioritised TORONTO, ONTARIO--(Marketwired - May 18, 2017) - Loncor Resources Inc. ("Loncor" or the "Company") (TSX:LN) is pleased to announce that exploration ground work has commenced on priority targets resulting from the 'VTEM' geophysical airborne survey undertaken by Randgold Resources (DRC) Limited ("Randgold") earlier this year on Loncor's Ngayu project in northeastern Democratic Republic of the Congo ("DRC"). Under the joint venture agreement signed in January 2016 (reference is made to Loncor's January 19, 2016 press release), Randgold will manage and fund exploration of the exploration permit areas comprising Loncor's Ngayu project until the completion of a pre-feasibility study on any gold discovery meeting the investment criteria of Randgold. Subject to the DRC's free carried interest requirements, Randgold would earn 65% of any discovery with Loncor holding the balance of 35%. Loncor will be required, from that point forward, to fund its pro-rata share in respect of the discovery in order to maintain its 35% interest or be diluted. Processed data and final products from the 10,013 line kilometre helicopter borne electromagnetic 'VTEM' survey completed over the Ngayu belt by Geotech Airborne Limited of Aurora, Canada have been combined with all other geological layers to complete an updated integrated geological map of the belt and to refine and prioritize areas of interest ("AOIs"). The figure attached to this press release (see below) highlights the preliminary four significant AOIs generated using pre-existing data sets and the VTEM data. The four preliminary AOIs have several kilometre long mineralised strike potential focused on extension of known mineralized trends as well as areas of geochemical anomalies and structural complexity. The four priority AOIs identified are summarized below: The initial work program will have a two-pronged approach: a geological review of all existing targets; and ground follow-up of remotely and conceptually generated AOIs to generate additional new targets. The belt scale exploration strategy of Randgold is to focus on the discovery of large high quality gold deposits by rapidly identifying and progressing targets that show the potential to meet these filters. Resources of greater than two million ounces of gold have already been identified within the Ngayu greenstone belt in the Makapela and Adumbi deposits and the objective is to further unlock the potential of the Ngayu greenstone belt for a world class discovery using cutting edge geophysics, geochemistry, structural interpretation and driven by an experienced and proven exploration team on the ground. Certain parcels of land within the Ngayu project surrounding and including the Makapela and Yindi prospects have been retained by Loncor and do not form part of the joint venture with Randgold. Randgold shall have certain pre-emptive rights over these two areas. Loncor's Makapela prospect has an Indicated Mineral Resource of 614,200 ounces of gold (2.20 million tonnes grading 8.66 g/t Au) and an Inferred Mineral Resource of 549,600 ounces of gold (3.22 million tonnes grading 5.30 g/t Au). William R. Wilson, a director of Loncor and a "qualified person" as such term is defined in National Instrument 43-101, has reviewed and approved the technical information in this press release. Loncor Resources Inc. is a Canadian gold exploration company focused on two projects in the DRC - the Ngayu and North Kivu projects. Loncor's Ngayu exploration permits cover a significant portion of the Ngayu Archaean greenstone belt in Orientale province in the northeast DRC and are its main focus. The North Kivu exploration permits cover a contiguous area of 13,210 km2. Both projects have historic gold production. Additional information with respect to Loncor's projects can be found on Loncor's web site at www.loncor.com. Additional information with respect to the Company's Ngayu project is contained in the technical report of Venmyn Rand (Pty) Ltd dated May 29, 2012 and entitled "Updated National Instrument 43-101 Independent Technical Report on the Ngayu Gold Project, Orientale Province, Democratic Republic of the Congo". Additional information with respect to the Company's North Kivu project is contained in the technical report of Venmyn Rand (Pty) Ltd dated February 29, 2012 and entitled "National Instrument 43-101 Independent Technical Report on the Manguredjipa Gold Project, North Kivu Province, Democratic Republic of the Congo".

South Africa hosts some of the world's largest known resources and reserves of minerals that are strategically important to the global economy. The country's mining industry contributes significantly to the national economy in terms of gross domestic product, export earnings, corporate tax receipts, remuneration earnings, and employment. Platinum, gold, and coal are significant minerals because they make the largest individual contributions to these economic indicators. Several factors impact the cash cost performance of operations that mine these minerals, thus affecting the future sustainability of these operations, which are generally 'price-takers'. It is therefore important that the cash cost performance of operations for these key minerals is analysed. Commercially available industry cost curves can be used for such analysis. However, some companies may not be able to afford to purchase these curves. This paper presents a simple Microsoft Excel® algorithm for constructing the curves. It also demonstrates how the constructed industry curves were used to analyse the cash cost performance of South African mining operations for the three selected minerals for the period 2007 to 2011, which included the 2008 global financial crisis. The analysis revealed that the operations were affected by several global and local factors during the review period. The work reported in this paper is part of an MSc research study at the University of the Witwatersrand. © The Southern African Institute of Mining and Metallurgy, 2013.

In recent times, there has been criticism of the minerals industry over the lack of quantifiable boundaries between Inferred, Indicated, and Measured resources. A recent initiative through the United Nations aims to try to converge the mineral resource classification systems. Since the oil and gas industry uses a probabilistic approach to defining reserve boundaries, it is appropriate to introduce a similar statistical methodology for minerals. The Venmyn Variance Tower has been developed based upon traditional statistics to utilize historical and ongoing information in order to quantify variance of geological and chemical parameters and the boundaries and logic for quantitative mineral resource classification. It is proposed that a less than 50% variance from the mean of all sample parameters is required to achieve the classification threshold to define an Inferred Resource whereas between 20-10% is needed for an Indicated Resource and less than 10% variance from the mean is needed to declare a Measured Resource. These limits are similar to those used by the oil and gas industry, and it is suggested that these thresholds be adopted as an industry standard to ensure consistent quantitative reporting. While this process is intended to use statistics of an orebody to provide quantifiable and defendable boundaries, it cannot be carried out unless the geology of the mineral deposit is understood and the borehole samples can be categorized into appropriate populations for which the statistics are valid. This means that competent geologists are always required to work with and understand the implications of the Variance Tower results. This paper is intended to form the basis of a series of publications that establish a process to take mineral projects along a quantifiable and logical development path. Hence, no specific field example of the practical application of this process is given here. © The Southern African Institute of Mining and Metallurgy, 2012.
