Assay Results

Assay results reported within this release include those provided by the Company's own

on-site laboratory facilities at Palito and have not yet been independently verified. Serabi

closely monitors the performance of its own facility against results from independent

laboratory analysis for quality control purpose. As a matter of normal practice, the

Company sends duplicate samples derived from a variety of the Company's activities to

accredited laboratory facilities for independent verification. Since mid-2019, over 10,000

exploration drill core samples have been assayed at both the Palito laboratory and certified

external laboratory, in most cases the ALS laboratory in Belo Horizonte, Brazil. When

comparing significant assays with grades exceeding 1 g/t gold, comparison between Palito

versus external results record an average over-estimation by the Palito laboratory of 6.7%

over this period. Based on the results of this work, the Company's management are

satisfied that the Company's own facility shows sufficiently good correlation with

independent laboratory facilities for exploration drill samples. The Company would expect

that in the preparation of any future independent Reserve/Resource statement undertaken

in compliance with a recognized standard, the independent authors of such a statement

would not use Palito assay results without sufficient duplicates from an appropriately

certificated laboratory.

Forward-looking statements

Certain statements in this announcement are, or may be deemed to be, forward looking

statements. Forward looking statements are identified by their use of terms and phrases

such as ‘‘believe’’, ‘‘could’’, “should” ‘‘envisage’’, ‘‘estimate’’, ‘‘intend’’, ‘‘may’’, ‘‘plan’’, ‘‘will’’

or the negative of those, variations or comparable expressions, including references to

future growth, results of operations, performance, future capital and other expenditures

(including the amount, nature and sources of funding thereof), competitive advantages,

business prospects and opportunities. Such forward looking statements reflect the

Directors’ current beliefs and assumptions and are based on information currently

available to the Directors. Several factors could cause actual results to differ materially

from the results discussed in the forward-looking statements including risks associated

with vulnerability to general economic and business conditions, competition, environmental

and other regulatory changes, actions by governmental authorities, the availability of

capital markets, reliance on key personnel, uninsured and underinsured losses and other

factors, many of which are beyond the control of the Company. Although any forward-

looking statements contained in this announcement are based upon what the Directors

believe to be reasonable assumptions, the Company cannot assure investors that actual

results will be consistent with such forward looking statements.
