Commenting on the markets, Evy Hambro, representing the Investment Manager 
noted:

Performance
China's third plenum was held during November, following which, the Chinese
government announced radical reform intentions. The rhetoric surrounding these
reforms, specifically the assumption that the government will deliver on their
implementation, was met with some enthusiasm and mining shares responded
positively. However, this was undermined by improving payroll data from the US,
which increased market fears that the Federal Reserve (the 'Fed') would begin
tapering earlier than expected. This sentiment, coupled with the market's
digestion of the comments on Chinese reforms, led to a fall in mining equities
over the month.

Base metals were down during the month, with copper holding up better than its
peers. Copper has the lowest inventories of the base metals and finished the
month at $7,054/t (Source: Thomson Reuters Datastream), down 2.6% in comparison
to aluminium which declined 5.8% and nickel which fell 7.6% (Source: CLSA).
Iron ore finished the month at $136/t, up 0.7% from the end of October (Source:
CLSA).

Better than expected global GDP coupled with the aforementioned positive
nonfarm payroll numbers in the US acted as headwinds to the gold price during
November. Mixed signals surrounding early tapering from the Fed sent the gold
price zig-zagging further down and the combination of these factors caused a
5.0% decline to $1,253/oz  over the month (Source: Thomson Reuters Datastream).
Gold ETFs have seen outflows every month of the year, this trend continued in
November with approximately 42 tonnes of outflows during the month (Source:
Scotiabank).

During the period, a number of brokers downgraded their mineral sands prices
(Goldman Sachs and Royal Bank of Canada) following a key industry conference,
based on the expectation of short term weakness across this group of
commodities. This news disappointed the market and mineral sands producers such
as Mineral Deposits, World Titanium Resources and Iluka Resources fell
sharply.  Gold producer, Barrick Gold Corp, suffered as the company announced a
$3bn rights issue to pay down its 10 year debt; this sent the share price
sliding lower. The global diversified company, Rio Tinto, announced that they
will achieve growth of 360 million tonnes with lower capital expenditure
intensity; the market responded favourably to this apparent display of capital
expenditure discipline.

Strategy/Outlook
The mining sector and other economically sensitive areas have struggled over
the last two years as the market has downgraded global growth expectations.

In the medium term, commodity prices are likely to remain range-bound as supply
and demand have come closer into balance. We expect constructive price pressure
to return for certain commodities, but for now mining companies need to be
focused on capital discipline, operational efficiency and growing margins
through cost control. In such an environment, well-managed mining businesses
should be able to generate free cash flow to return cash to shareholders and
should see their share prices rewarded as a result. In the Company, we are
looking to identify the winners and the stock specific stories that have been
neglected in the risk averse markets of the last two years.
