The Company has also completed an updated technical report in support of the statement of estimated mineral reserves and mineral resources, entitled "Gahcho Kué Mine NI-43-101 Technical Report" and dated March 16th, 2018 (with information effective as of December 31, 2017) (the "2017 Technical Report") as prepared and completed by JDS Energy & Mining Inc.

Total estimated probable mineral reserves for the Gahcho Kué diamond mine at December 31, 2017 are summarized in the following table.

Notes to The Mineral Reserve Statement:   

1. Mineral reserves are reported at a bottom cut-off of 1.0 mm
2. Mineral reserves have been depleted to account for mining and processing activity prior to Dec 31 2017.
3. Q4 2017 depletion is based on forecasted values and may differ slightly from actual depletion.
4. Mineral reserves are based upon the updated resource model (2017) and therefore reflect any changes to the estimation of tonnes, grade and contained carats within that resource. Details on resource changes are summarized in Section 14.
5. Prices used to determine optimal pit shells have been escalated by factors varying by pit, which are indicative of the respective pits timing and duration.

Total estimated mineral resources for the Gahcho Kué diamond mine at December 31, 2017, exclusive of estimated mineral reserves, are summarized in the following table.

Notes to The Mineral Resource Statement:   

1. Mineral resources are reported at a bottom cut-off of 1.0 mm. Incidental diamonds are not incorporated in grade calculations.
2. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
3. Volume, tonnes and carats are rounded to the nearest million. 12,300t of inferred resources stockpiled @ 115cpht (14,250cts total).
4. Tuzo volume and tonnes exclude 0.6 Mt of a granite raft and CRX_BX.
5. Resources are exclusive of indicated tonnages converted to probable reserves.
6. Resources have been depleted of any material that was processed prior to and including Dec 31 2017. Q4 2017depletion is based on forecasted values and may differ slightly from actual values.

Except for statements of historical fact relating to Mountain Province, certain information contained herein constitutes forward-looking statements. Forward-looking statements are frequently characterized by words such as "anticipates," "may," "can," "plans," "believes," "estimates," "expects," "projects," "targets," "intends," "likely," "will," "should," "to be", "potential" and other similar words, or statements that certain events or conditions "may", "should" or "will" occur. Forward-looking statements are based on the opinions and estimates of management at the date the statements are made, and are based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Many of these assumptions are based on factors and events that are not within the control of Mountain Province and there is no assurance they will prove to be correct.

Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include variations in ore grade or recovery rates, changes in market conditions, changes in project parameters, mine sequencing; production rates; cash flow; risks relating to the availability and timeliness of permitting and governmental approvals; supply of, and demand for, diamonds; fluctuating commodity prices and currency exchange rates, the possibility of project cost overruns or unanticipated costs and expenses, labour disputes and other risks of the mining industry, failure of plant, equipment or processes to operate as anticipated.

These factors are discussed in greater detail in Mountain Province's most recent Annual Information Form and in the most recent MD&A filed on SEDAR, which also provide additional general assumptions in connection with these statements. Mountain Province cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail. Mountain Province believes that the expectations reflected in those forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in this news release should not be unduly relied upon. These statements speak only as of the date of this news release.

The reader is cautioned not to place undue reliance on forward-looking statements. Statements concerning mineral reserve and resource estimates may also be deemed to constitute forward-looking statements to the extent they involve estimates of the mineralization that will be encountered as the property is developed.
