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

Performance
September saw an improvement in risk appetite. The decision from the US Federal
Reserve to delay the tapering of its Quantitative Easing (QE) programme came as
a positive surprise for equity markets while the re-election of Angela Merkel
in Germany also contributed to the positive performance of European equities.
On the macroeconomic front, Chinese leading indicators surprised on the upside
with industrial production, investment growth, electricity production and PMIs
all showing improvements.

Encouraging data from China and the surge in risk appetite was positive for
most metals and in particular for copper which added 3.0%. Nickel, aluminium
and tin added 1.2%, 1.8% and 9.8% respectively, in September. Over the month,
steel inventories in China remained low while iron ore inventories increased as
more supply came into the market. Despite a negative performance of
approximately -4%, the iron ore price remained more resilient than expected,
staying above $130/t.

Gold's turbulent year continued into September with the gold price falling 
$100/oz as concerns over the prospect of military intervention in Syria eased 
and expectations of QE tapering by the Federal Reserve began to be factored 
into the gold price.  News that the FED would not commence tapering caused the 
gold price to rise sharply towards the end of the month; however, this rally 
quickly faded.

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, be in a strong position 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.
