Overview

Griffin Mining Limited ("Griffin" or the "Company") and its subsidiaries (together the "Group") achieved record results in 2011 with record production and record profit before tax of $39,953,000 (2010: $11,236,000). The record results follow the completion of processing plant upgrades, increased mining rates with uninterrupted production throughout the year.

Revenues increased to a record $79,062,000 (2010 $41,050,000) with record metal in concentrate sales resulting in increased profits from operations of $36,832,000 in 2011 from $13,143,000 in 2010. In summary:

• Record 695,848 tonnes of ore were mined, compared to 389,496 tonnes in 2010, a 79%

increase;

• Record 715,955 tonnes of ore were processed, compared to 420,928 tonnes in 2010, a 70%

increase;

• Record 36,283 tonnes of zinc metal in concentrate were produced, compared to 22,044

tonnes in 2010, a 65% increase;

• Record 10,281 ounces of gold in concentrate were produced, compared to 7,067 ounces in

2010, a 45% increase;

• Record 312,509 ounces of silver in concentrate were produced, compared to 157,679 ounces in 2010, a 98% increase; and

• Record 1,909 tonnes of lead in concentrate were produced, compared to 690 tonnes in 2010, a 177% increase.

Despite market prices for zinc metal in 2011 remaining generally unchanged from 2010, the average price per tonne of zinc metal in concentrate received increased to $1,546 in 2011 from $1,409 in 2010, indicating increased demand for zinc concentrate within China. The average price received for all other metals in concentrate sold in 2011 also improved over that achieved in 2010 with the average price received for gold being $1,438 per oz (2010 - $1,027), silver $26 per oz (2010 - $13.50) and lead $2,054 per tonne (2010 - $1,741).

Costs of sales increased in 2011 to $31,918,000 from $16,780,000 in 2010 due to increased production and mining and haulage costs increasing as lower mine levels were accessed. With the commissioning of the upgraded processing facilities, processing costs per tonne fell during 2011 as economies of scale begin to be felt with increased production.

Group operating costs, including mine site administration costs, fell in 2011 to $10,312,000 from $11,127,000 in 2010.

With cash balances averaged some $79 million in 2011 the Group benefited from interest receipts on those funds of $616,000 in 2011 (2010 - $350,000).

Foreign exchange gains of $2,588,000 were recorded in 2011 (2010 - $38,000). These gains arose on Renminbi accounts and sterling bank deposits. The Group is now permitted to hold Renminbi funds in Group bank accounts in Hong Kong.

Griffin's 39.2% share of the losses of Spitfire Oil Limited ("Spitfire") in 2011 was $118,000 (2010 - $109,000).

The increasing upward trend in metal prices led to no metal put options being purchased in 2011. The residual value of zinc put options purchased in 2010 of $14,000 was written off in 2011 (2010 - $2,224,000).

Income taxes in 2011 were $12,256,000 (2010 - $2,376,000). This increase reflects larger profits and an increase in PRC income tax from 12.5% to 25% due to the end of the pre-construction tax concessions enjoyed by Hebei Hua Ao Mining Company Limited ("Hebei Hua Ao") and the PRC withholding tax of 10% on dividends paid overseas.

The minority party's share of Hebei Hua Ao's profit of $11,882,000 (2010 - $6,116,000) resulted in an attributable profit to Griffin of $15,815,000 (2010 - $2,744,00).

The Company's basic earnings per share improved to 8.96 cents per share from 1.51 cents per share in 2010 with diluted earnings per share of 8.76 cents per share in 2011 (2010 - 1.49 cents per share).

During 2011, 5,040,000 (2010 - 1,580,000) ordinary shares were bought back on market for cancellation at a cost of $4,977,000 (2010 - $1,146,000) thereby reducing the number of Griffin shares in issue to 175,501,830.

Net cash inflow in 2011 increased to $23,433,000 (2010 outflow of $370,000) despite the share buyback programme, due to increased profits and lower capital expenditure.

Attributable net assets increased to 87 cents per share as at 31 December 2011 (2010 - 78 cents per share).

Chairman's Statement:

What began as a remarkable journey in 1997 has now culminated in the Company's 88.8% ownership of a world class, extraordinarily long mine life, operating mine and a mineral province whose potential has only just begun to be tapped.

In the past year, the Company has striven to deliver on its promised potential. Financially, Griffin achieved a record profit before tax of $39,953,000, a 256% increase from the $11,236,000 result recorded in 2010.

Operationally, a record 715,955 tonnes of ore were processed compared to 420,928 tonnes in 2010, a 70% increase. A record 36,283 tonnes of zinc metal in concentrate were produced, compared to 22,044 tonnes in 2010, a 65% increase; a record 10,281 ounces of gold in concentrate were produced, compared to 7,067 ounces in 2010, a 45% increase; a record 312,509 ounces of silver in concentrate were produced, compared to 157,679 ounces in 2010, a 98% increase; and a record 1,909 tonnes of lead in concentrate were produced, compared to 690 tonnes in 2010, a 177% increase.

Geologically, the announcement of the new JORC Resource for Zones II and III at Caijiaying displayed the true potential of the orebody with a 32% increase in the Mineral Resource from 38.6 to 51.2 million tonnes, representing a 50 plus year mine life at an increased throughput rate. Not only was the Mineral Resource increased in Zone III, even with the mine depletion, by 8% from 29.1 to 31.5 million tonnes, but the Mineral Resource at Zone II was increased by 107% from 9.4 to 19.6 million tonnes. This is highly significant in that it will provide a second source of ore for the mill to service a planned increase in throughput in the near future. Further drilling results since the calculation of the new JORC Resource have only increased the likelihood of even further resource upgrades in the future.

Of course, the major achievement of 2011 was the announcement on the 10th May 2012 that the Company had entered into an agreement to increase its majority in Hebei Hua Ao Mining Industry Company Limited ("Hebei Hua Ao") to 88.8% and extend the term of the Hebei Hua Ao joint venture through to 2037 ("the Transaction"). The enormity of this Transaction should not be lost. Firstly it allows for full management control to now rest with Griffin staff with the "government" layers of management abolished. Secondly, it allows planning with confidence to now proceed to apply for, and obtain, a mining licence at Zone II and to plan for an upgrade to the processing facilities and the necessary below ground development to increase throughput at Caijiaying up to 1.5 million tonnes per annum. All this with the security of knowing the Company will be at Caijiaying at least until 2037 and reaping the vast majority of the profits emanating from the Caijiaying mine.

Corporately, the Company continues to examine a vast array of possible corporate and asset acquisitions to see if they can meet the stringent financial, operating and political criteria demanded by the Company. In addition, the Company continues to evaluate and discuss the listing of Griffin on the Hong Kong Stock Exchange with a significant number of investment banks in Hong Kong.

As I have mentioned far too many times, all mining companies are subject to the vagaries of commodity prices. In normal circumstances, these prices are substantially governed by supply and demand equations and, to a lesser extent, commodity traders. Unfortunately, since the Global Financial Crisis in 2008 and the fiscal irresponsibility of investment banks, commercial banks and all levels of government, economic growth, so often driven by debt, has faltered. Whilst China and the emerging markets continue to grow and demand raw materials, the outlook looks rosy, particularly for the supply deficit predicted in the zinc market in the next 2 years. However, uncertainty remains with the mountain of debt in the public sector, the undercapitalized banking sector and the contracting economies of the European Union and the inevitable consequences for world trade, growth and commodities demand. We can only sit and wait to see what will be the outcome of this fiasco.

Dividend

The directors do not recommend payment of a dividend at this time in view of the use of the Company's financial resources to acquire a further 28.8% interest in Hebei Hua Ao Mining Industry Company Limited and an extension of the term of this Joint Venture.
